That a wet bolt kit, and better tires than the factory Trail King are a necessary upgrade. A need vs a want.

That's a tough one- I went three years before my DW agreed that the money would be well spent- I argued the tread was almost gone but we only had about 7K miles on the tires. I also pointed out the noise the trailer made as we crept around the various parks. But I argued for the Morryde CRE 3000 in addition to the wet bolt ket since the labor cost was negligible. I was able to take advantage of a Trip from El Paso to Disney World to argue that the CRE 3000 would help in the suspension and make the ride better for everybody. And I argued that getting the best tire we could afford would be a huge upgrade over the China bombs that were previously on there. She agreed and we did it, I looked at the Lippert Shock system as well but that was a bridge too far at the time. I also agree that reading this and other forums are a huge help to educating you on the issues, upgrades and potential dangers that these things can become. If your DW is like mine, she won't read these forums, she leaves that up to me so the challenge isn't just getting her to agree but also to read forums like this and that maybe too much! Baby steps... I would also suggest framing the the tire conversation how it's a benefit to her and the family, make it about her and them and less about how it's something that you just want to do (despite that it's really a safety factor). I suggest prioritizing with the tires being #1 and wet bolt kit ...not #1. Another thing I would recommend when upgrading tires- don't forget to opt for the metal stems rather than the standard ones. If you do that, you could set yourself up for a future tire pressure monitor, but again... baby steps. I would also frame the tire discussion in terms of the damage (not to mention safety) that a blow out could do to the coach and what that would do to your insurance rates (they will go up). So tires are an investment and insurance against potential future problems. But in fairness to her, if you just pulled your coach off the lot she probably sees buying tires now as buying them twice and nobody wants to do that. Like I said, I did pull my 316RL 7K miles (mostly highway) around Southern GA to Central FL up to VA (in the early Summer) and then from VA (Williamsburg area) to El Paso TX in late summer. Point is, those miles were on the China bombs and I certainly exceeded the 65mph speed rating. Was I lucky, absolutely and I don't know that I would do all that again. And that is the other aspect, those China bombs are typically rated for 65mph max and if you exceed that an cause an accident when they blow, you will probably be help negligent if they prove you were speeding. Sorta like being overweight and causing an accident as a result of being overweight... "you're screwed and you know it!" (he says with the best Scottish accent). The low speed rating on those China bombs would also be part of the safety argument if I were presenting it.
You may also consider a slow build up of data and evidence in order to chip away at her rather than putting it all out there.
Good Luck!

What I neglected to mention is that she controls the finances, I just bring in the money. Its been 3 years and she still hasn't let me forget I almost died when I ordered our TV without her knowledge. There are a lot of other wants too, most of them will increase the value of our trailer. Since the trailer is encapsulated in snow now about all I can do is plan for the spring.

Not sure about the wet bolt kit, but convincing her about better tires is a no brainer. I sold my DW just by telling her how much damage a blown tire can do to the trailer vs how much a new set of boots cost ... $thousands vs about $400-500. It's a no brainer for us! Also, had to convince her that a TPMS was good insurance too. Now she monitors the tire pressures while she knits and I drive, and we both travel with relative peace of mind about what's happening waaaay back there on the trailer.

busterbrown
02-05-2019, 11:32 PM
It's a pretty convincing argument when you have photos and real world shared experiences that prove the destructive power of a shredded tire carcass at highway speeds. A quality set of $100 tires is relatively cheap insurance to help mitigate a vacation ending failure. As others have stated, let the DW read a few posts on this or any other RV forum. She'll be a true believer.

FWIW, a wet bolt kit is much easier on the pocket book than a set of tires if you're able to do the work yourself. But if your like me, the wet bolt kit can be the catalyst for new heavier axles and springs.

"There are a lot of other wants too, most of them will increase the value of our trailer" - This comment worries me as I'm extremely confident that any given trailer is losing value after delivery no matter the money, effort, or upgrades "invested". A $5,000 solar and LiFePO4 battery bank may be a wonderful convenience for the coach's owner. But for all intents and purposes, it's a convenience (upgrade) that will depreciate just as quick as the RV itself. It may help sell the coach quicker when that time comes. But I don't think people invest in a better mattress or nicer sofa in their fifth wheel in the hopes of "value-added" profits. YMMV

Mike, Here's what you own:
2016 Ford F350 CC 6.7 4x4 SRW (Ghost Rider)
2017 Cougar 29 RKSWE (The Tumble Weed)
Connected by a Curt 15K WDH W/Sway Control
A late model F350, a really nice RV, the best (arguably) WDH on the market and you get grief for an expenditure of $350 to $400? I think Grandma's old saying that is quite apropos would be that DW is being penny-wise and pound-foolish. Carlisle's can be had for about $75 apiece at your favorite Wally World. I don't care if your wet bolt kit ever gets installed, but tires affect us all. Your insurance company will thank you.

Ask for forgiveness afterwards instead of asking for permission. :D

In the grand scheme of things you are talking a couple hundred dollars for new tires versus a couple thousand and/or the headache of dealing with insurance and sitting on the side of the road for a while if a tire goes.

I’m replacing the Maxxis tires on ours this summer before taking off out west. The ones on the 5er are “only” going to be 5 years old this spring and have good tread depth. But I’m not driving a few thousand miles with them. But I am guessing that is going to be a discussion also on this end....

How often do you use your RV? Full time or weekend trips? Tires are a matter of safety, a wet bolt kit is not a necessity even though it does extend the life of the suspension. Wet bolts are a nice upgrade but not life threatening like tires could be. Are finances that tight or is she just a miser? lol. If you can get one go with the tires. Trailer Kings are crap. I went with the Goodyear Endurance and the TK's only had 3K miles on them.

As for the wet bolts, are you mechanically adept that you can do it yourself? The bolt kit is cheap, labor not so much. If you don't want to do it yourself then take it to a local mechanic or frame shop and have them do it instead of an RV dealer. It is a worthy upgrade and will certainly quiet down the suspension.

The tires have me paranoid, living in Alaska with long distances between places and services. We travel "heavy", loaded fresh water tanks etc. to go a week to 10 days at a time
Jim, Wally World does not sell tires up here and Sams Club closed last year not sure if Costco even has a trailer tire selection, they are finicky about putting tires on regular vehicles any ways. Tires are expensive up here even in the metropolis of Los Anchorage $700 to replace the TK bombs with the GY Endurance. I might be able to get a little better price shopping around but I went straight to the distributor for the Goodyears.
As for the wet bolt kit, I cringe at the noises the trailer makes when I pull in to the cul-de-sac and have to turn around at the end. In addition to the wet bolt kit I have the crossmembers on the list too. Wet bolt kit and three crossmembers are a little over $400 from Amazon. and I will be able to install.
The roads are not the greatest up here with the frost heaves and constant summer construction. just thinking this will help preserve the trailer.
Other things included on the list are the Furion rear observation system $550, and replacing the factory steps with the Mor- Ryde step above system. Basically all safety and security up grades. If these ad monetary value to the trailer when it comes time to trade/ upgrade fine., but more importantly they will give me piece of mind.
So in closing about $1700 in upgrades not including the steps, I have not priced those out yet

My DW keeps track of everything we spend (I spend) on Quick Books. She has a simple process for making sure I don't spend too much by simply allocating additional money for airline tickets so she can visit the grand kids on a dollar for dollar basis based on my expenditures. So, a new set of skins for the Cougar is budgeted for $1000 not $500:D
If I try to use the "Needed and Necessary" argument I simply get the "Time with the Grandkids is Priceless" response. :facepalm:
The system keeps me from buying to many gee-gaws for the Cougar and the grandkids get plenty of visits from grandma.

This is one example, there are different ones depending on which axles and springs are on your trailer.

Mike Thanks going to upgrade the old Cougar to something just a bit bigger.

A note on upgrades. Current one was going to stay so we upgraded the very uncomfortable hide-a-bed couch to 2 Lazy Boys ($2K CDN). Sold the couch. When dealing on a new TT the salesman said the upgrade actually decreased the value on a trade. Did too many upgrades on this rig to count but they use book value.
Point being do upgrades for your enjoyment. There is no value at the other end.

JRTJH

Almost any mod you do to your RV is "for your enjoyment" and in all probability won't even be considered when you decide to trade it in. Usually, the dealer won't even ask if you did anything "special" to your RV.

There are numerous "posted, personal accounts" on this and every other RV forum where you can read, "They gave me a trade in value of my current trailer and never looked at it". Typically, most RV dealerships work with enough "front room and trade value" that they can offer the "book wholesale value" simply by asking, "Does your current trailer have any problems?" If you answer, no, it's in good condition, most dealerships can absorb any cleaning/rehab costs out of the profits they will get from the resale of your tradein and/or even if they have to sell it for what they gave you, there's enough profit figured into the sale of the new RV to absorb the little cost they'll have to clean/condition your trade.

If there's more cost than they can absorb, they park your trade on the back lot and either wholesale it or sell it for what they have invested (even if it's a loss) rather than invest more in a "losing investment". The frequency of losses is so low that it almost never happens, so most dealerships don't do the "bring your trade in down so we can check it and give you a dollar amount". Once they have you in the showroom, wanting to buy, they "facilitate your urges" and get your signature on the bottom line. Through years of negotiations, they already know what their profit margin will be, even before you walk into the dealership and tell them you have a trade....

So, I am planning/thinking about upgrading tires this spring before camping/hauling season. The 26RBPR is a 2018 with brand new tires on it. But from what I have read here you guys have made me nervous about the tires. Is this paranoid foolishness on my part? Could I go a season first? I will probably haul about 3,000 to 5,000 miles this next season. I have thought about the GY Endurance. Also this thing about the wet bolt kit. How do you know which kit fits your trailer? Is it standard? Spring width? Eye circumference?
Thanks in advance.

What tires on your trailer (brand/size)? Keystone says it has st205/75r14 lrd tires. If so, it appears the tire is rated at 2040 from what I can see. Your trailer has a gvw of 7500 so that gives you a "little" bit of a cushion; the way I figure things. Many, as well as the manufacturers, believe the tires should only have to carry the weight of the trailer less the tongue weight. I disagree completely. I think they should be able to carry the gvw of the trailer with a nice cushion - but that's just me....after a blowout with tires barely rated to carry the trailer.

With what you have there is about a 160lb. cushion, per tire, over gvw - and remember that the weight on each tire is more than likely different due to loading. I don't even know if the make an LRE in that size but doubt it so it may be the best loading scenario you can come up with. The brand of the tire....some think that the only reason a tire "blows" is because of poor maintenance by the owner. I can personally tell you that is erroneous. There are some that run "china bombs" for a long period without a failure. But, the are also the ones that fail far more than any others. Yes, they are what is primarily on most new trailers, but, it is odd that when they are replaced with another, highly regarded, Chinese tire - those things cease to happen.

It isn't "paranoid foolishness" to worry about those tires as much as has been written about them (china bombs). Again, it would help to know the brand. All Chinese tires, from all plants, are not equal. Your talking about 3-5000 miles this season. As a reference point, my Trailer King blew at just over 3000 (as I recall) miles with 7k in damages.

JRTJH
02-06-2019, 01:48 PM
To add to Danny's information (all of which I agree with). All ST tires "degrade" in strength at about 10% per year. So your tires, rated when new to carry 2050 pounds at 65 PSI at 1 year old will carry about 1845 pounds, at 2 years old will carry about 1645 pounds and at 3 years old will carry about 1435 pounds. Your trailer has 4 tires, so at 3 years old, the tires will have degraded by about 30%, meaning they can "safely" carry about 1435 each (1435x4=5740) or about 2460 pounds LESS than the 8200 pounds that's "stamped on the sidewall"....

While there is (to my knowledge) no "hard and fast science" that can tell you specifically whether your tires degraded at the 10% per year or whether they degraded at 7% the first year and 9% the next two years or ?????

So, while there is no "concrete data" that I know of, the 10%/year is a "best guess guide" to how tires weaken in use. What makes them weaken? Lots of things, sitting for months in storage, moisture causing "rot" in the polyester cords, UV rays degrading the rubber, heat generated by sidewall flexing, loading/use placed on the tire structure, ruts, sidewall bruising from curbs, and a long list of other "damaging conditions"....

So, thinking that you have 8200 pounds of capacity on 3 year old ST tires is, in most people's opinion, optimistic at best and likely foolish in reality.

I keep tires on my trailer for 3 years and then take them off. I'll use them on my flatbed trailer for general cargo (7200 pound GVW) for the next three years, then toss them. At 30% less strength, they're OK for that traielr but not on my Cougar (10,000 GVW).

ADDED: I think I used 2050 to calculate the degredation and your tires are rated at 2040 ??? If so, then use the above figures as a generality rather than as "calculations for your specific tires"....

German Shepherd Guy
02-06-2019, 02:14 PM
You guys are awesome!! So I will put new tires on this spring. GY endurance st217/75-14 are what will fit. 204s are what came with the trailer (from China) but the 215s increase from 2040 to 2200. It also appears my rims that came with the trailer are OK for this. Does this sound OK to you two? John, Danny I have really come to trust your judgment, so what do you think, is it a plan?

Canonman
02-06-2019, 03:34 PM
I'll chime in here and suggest 2 things. 1, see if you can bump up a load range again to allow for added load carrying cushion. 2, think seriously about a Tire Pressure Monitoring System (TPMS). We did both and the TPMS saved our vacation to Grand Canyon by alerting us to a temperature issue with a brake that could have been catastrophic.

sourdough
02-06-2019, 04:34 PM
If the wheel will support the additional weight and your tire spacing will accommodate the increased width of the tires it would appear to me that it would be a go. I don't know what kind of spacing you have between your tires but it looks like the 215 will increase the diameter of the tire about .6", so maybe a little over 1/2" decrease in the gap between the existing tires - if my mind isn't failing me or the fumes from this chili I'm making isn't getting to me:eek: That additional carrying capacity would look good to me.

As far as a TPMS - if you don't have one you should get one. It is a REAL relief and can actually, hopefully avert a potential disaster. I never thought ours would give me the kind of "peace" I have now vs before when I had no idea what the pressures/temps were doing. Not too expensive and easy to install. JMO

So to update the quote I got for tires is $700 and some change out the door. 4 GY Endurance ST 225/75 R15 load range E. GVW of my trailer is 8800#. It breaks down to the tires being $136 each and the rest valve stems, labor and disposal fees I am gonna shop around to the limited selection of tire stores we have here localy and see if I can get a better price. Are there other alternatives to the GY Endurance?

JRTJH
02-06-2019, 06:13 PM
Many of us currently have Carlisle Radial Trail HD or Radial Trail RH (the predecessor). Maxxis 8808 is the third in the "quality tire category"...

GY Endurance has only been on the market about 18 months now. It's reputation so far appears great. But, there's no "long term consumer experience". Lab testing, for what that's worth is good (from what GY tells us) but that's not the same as "real people with real trailers being dragged through the outback".... Endurance has the promise of being a great tire, some believe it's already there. Others of us are taking the "wait and see" approach.

Meantime, I've got Carlisle's and my next set will also be Carlisle's.... YMMV.

02-06-2019, 08:58 PM
Just to add to the good advice already provided... If you do add external tpms sensors, be advised to invest in quality HP metal valve stems. These Ford n-1600 stems (http://yourtireshopsupply.com/product/512/n1600-ford-series-truck-valve-han1600) are high quality that a few of us on here are using. About $20 for 4 shipped to your front door. They include small extenders that can be removed.

All she will need to experience is a blow out on one and she will be convinced! We thought ours was good--the tread was good, but we were talking of getting tires before we headed south. On the way to Wyoming for a two week vacation, we had a blow-out! Not fun. We were lucky enough to not tear the side of the RV out, but it was scary. We got it changed, turned around and went back home to our favorite tire dealer. I (the DW) told the guy we wanted 4 new ones and not the Trailer King. My hubby just stood back and told him to give me what I wanted! LOL . BTW, I had been following these posts on tires so I pretty much knew what we needed. My DH doesn't do much on the computer so he takes me at my word!

You need to do a little research to see what you have near you. If you are full timing, can you close it up for a day to take it in and have it done? If so, scout out the local tire shops to see who has enough room for you to get it in/out. Don't call and ask, you could easily get an answer that might get you in a bind.

If that isn't available/possible, is there a tire shop that will send a truck out to put them on for you? My tire shop back in TX does it all the time, but, they are equipped with truck to go into the fields and work on tractors so they have no problem going to a location (close) with all the tools needed to do whatever is required. This option would involve more expense but you have to pay them for the services they provide.

Easy, I had two Trail King tires blow apart within 2 days of each other. Both tires had good tread on them. TPMS saved our lives by signaling immediately that a tire blew. One one each side of the same axle. $13,000+ damage to both sides, camper has been in shop for 4 months, insurance a PITA to deal with. Have no clue from shop when it will be finished. Missed 3 scheduled trips due to damage.

I replaces all 5 tires as I didn't want to take another chance. I have pictures of the damage to the TT and pictures of the shredded tires if you want to see.

Luckily, the DW has a lot of respect for the experience on this site. Already got approval for the new set of tires and rims, just need to get it out of storage to double check some measurements. (DW: "And you're sure those are the right ones?" DH: "Yes. Well. Okay, I can wait to place the order.") Currently preparing the case for wet bolts and better springs than the "strips of sardine cans" that came with the trailer. :-)

I doubt you need to be concerned with new rims as well. From what I can find your trailer came with 16" wheels and the tires available should carry you. It shows ST235/80r16LRE tires as OEM. They are rated for 3520lbs each. I don't know how you load your trailer but if you run pretty high in your weight range you could upgrade to the LRF tires when you replace them and give yourself about 340lbs more safety margin per tire - if your wheels are rated for that weight (3860) or the pressure (95psi). One or both of those numbers are probably stamped on the back of the wheel.

How "heavy" are you? A 15% Reserve Load, based on actual individual tire scale readings, can go a long way toward getting reasonable tire life.

My weight is 11000 (max is 13000), the tires call for 80 psi.
That is the size tire tho, trailer king.

How does that work? 3520 x 2 does not equal the weight...

My weight is 11000 (max is 13000), the tires call for 80 psi.
That is the size tire tho, trailer king.

How does that work? 3520 x 2 does not equal the weight...

Don't you have two axles with two tires on each axle?

3520 X 4 = 14,080.

1. Cheap tires supplied with trailers. Here's a picture of my blowout. The tire had about 1800 miles on it and was 1.5 years old. The tire has a 75 mph speed rating. The tire was loaded to 55% of its load rating. It never saw a speed over 65 mph. It had tpms on it since day one and was never run under pressure. It had never hit a curb or pothole. It was inspected prior to the trip.

The tpms immediately signaled low pressure. I eased on the brakes to pull over and since this tire was no longer supporting any weight it immediately locked up. Because we didn't hear what sounded like a blowout and there was no change in handling I wouldn't have pulled over, I would have checked the mirrors and kept going. The tpms warning and the tire locking up prevented damage to the trailer.

I had America's tire check the rest of the tires and 2 of 3 had bulges. Heaviest loaded tire was at 70% of capacity (LRD). They were replaced with Carlisle Radial Trail HD LRE.

2. When inspecting the running gear one shackle bolt looked out of place compared to the others. Found the shackle bolt had worn through about 40% of the shackle when it was disassembled. I think the bolt was allowed to spin during assembly at the factory stripping out the shackle hole and the serrations on the bolt acted like a file and were wearing away the shackle. The nylon bushings had not worn all the way through but were very thin.

I replaced the factory shackles with heavy duty shackles and installed Never Fail bushings.

BikerRN1 (http://www.keystoneforums.com/forums/member.php?u=26200) have you confirmed that no one tire has more than 3200# actual load? (90% of 3,520 tire capacity)


Where are the roads that have no pot holes?


TPMS do not warn of blet separation which is what appears to have happened to you. How old are the tires?
Do you do an anual"Free Spin" inspection? That would have probably shown an indication of the separation.



If you have confirmed you only have 1,936# on the heaviest tire you have one of the lightest trailers on the road. Your 11,000# scale weight doesn't work out with the other load numbers.

Just do it because you know you need to!
