Another China Bomb Story
More China Bomb issues. Was camped next to a couple with a year old Jayco TH this week. He has been on two trips and lost a tire on each one. The first trip was mainly cosmetic damage that he repaired himself with some signs left to remind him. The second trip is costing him his $500 deductible with some pretty serious damage to a slide out. We talked for a bit, he tows a little fast, about 70, runs proper air pressures. He thought about getting a TPMS before this last trip, but decided not to. Now he wishes he had. The system likely would have saved his $500 deductible and a good bit of headache. He has all new tires now so I'm not sure what he had on for OE tires. Still only went with LREs which I think was a mistake, but at least they're not the OE tires. Another lesson learned, don't wait to change the OE tires, don't tow too fast, and a TPMS is likely one of the best investments you can make that will pay for itself.

X2 on adding a TPMS and upgrading the OE tires. We upgraded to Carlisle tires LRE and added the TPMS prior to our trip to Grand Canyon. The TPMS saved our vacation by warning us of a wheel overheating problem. One of our trailer brakes was locking up causing the overheating. We were able to clear the problem and completed the trip with no further issues. Like Brent said watch your speed, keep the pressures up and use the monitor system to give peace of mind.

Couldn't agree more with the above posts. Especially the comments regarding speed. I know - everyone is in a HURRY! When I drove OTR in a semi, I used to get impatient with "the old guy in the MH with nowhere to be and all day to get there". Now that the DW and I are retired WE are the rolling road block holding up traffic. Putting aside the fact that the west coast states require you to travel 55 mph when towing, I try to keep our speed at 60 mph. The truck seems to like it there. Besides - at 55 mph, our average daily mileage of +/- 375 miles takes 6.8 hrs compared to 5.36 hrs @70 mph. I've lost count of how many times we are passed (like we are up on jacks) only to pass them by at a rest area further up the road. To each their own - but - why not slow down and enjoy the trip? Plus the added benefit of saving a little of your truck and your tires for tomorrow. Just sayin"

Depending on the trailer,,E rated LTs are usually plenty tire up to about 12K (my opinion with some experience, of course). Once you get 'up there' in weight, then you need to start thinking of 'G' rated tires with wheels that will work with 110psig which Keystone's common Sandel aluminum wheels wont.
I wont even mention various tire brands as it's like comparing the Big Three TVs
It amazes me that most folks don't do any basic research on their trailers - just go into a dealer, plunk down some hard earned bucks and drive off into the sunset towing their new RV with nary a care in the world until BANG, clatter, crunch and a roadside stop while others pass by at near warp speed!!

I pulled the new Montana home from the dealer this week. Getting it loaded and a few mods completed. Verified with the manufacturer they are rated 110 psi. Before the 1st trip G rated Sailun tires will replace the E rated Rainier tires. At 4080# per tire there will be much more than enough cushion.

Any idea if the 2 blow outs were on the same side. If so, I would say maybe the overloaded remaining tire finally gave out causing the 2nd.

Opposite sides. The first was the front tire on the passenger side, the second was the rear tire on the drivers side.

Ok, good to know, thanks for posting that information. That points a lot more to just plain out junk tires.

This just happened to me on our Road Ridder's yesterday coming home from our trip. Was doing 60mph when it blew but had no issue with sway or losing control. Time to pay the deductible and find some new shoes for the camper.

That was my first thought as well. If I remember, sopranos27 just recently bought his 2012 trailer as a "new to me" purchase. I'd be interested if these were the original tires on the trailer and if so, they could be 6 or 7 years old. If they are not the OEM tires, the date of manufacture is on the DOT stamp which is molded into the tire sidewall. It will be a 4 digit number. The first two numbers are the "week of the year" and the second two are the "year". I'd suspect these tires are OEM and were "long overdue for replacement"....

That's my thought. Hate to change my Maxxis out next spring before the season, as they are still looking good. Going to be four yrs old next year, though. Ah well, some local rancher will buy them.

They were on the trailer when I bought them and am kicking myself for not getting new tires in the deal. I'll take a look at the DOT stamp but this trailer is not moving until new shoes are put on. They were D range tires but I think I'll. E looking at some LRE tires.

I went to Carlisle Radial Trail HDs and went from LRD to LRE. GREAT improvement over the Ds and they have performed flawlessly (now, hope I didn't jinx myself since we are leaving for FL in about 6 weeks....if IRMA will leave my place alone.....)

Just a note: Maxxis trailer tires have a 6 year warranty from the date of manufacturer.
Maxxis does not list an age-out clause in any of their trailer tire publications.

If you consider the aging of the polyester cording I think you'll answer your question. "Larger size polyester" is used in ST tires to give them the extra load capacity over LT tires. The polyester weakens as it ages. Estimates are 10% per year. So, tires size 235 80R16 LRE are rated at 3520 pounds at 80PSI. The 326SRX and 326SRXWE don't weigh the same, so taking the heavier of the two, the 326SRX at 9745 with a payload of 2915 and a pin weight (empty) of 2260 (23% of 9745), if we calculate the GVW pin weight the same 23%, that would be 12560x.23=2889. So 12560-2889=9671 (on the axles) divided by 4 tires would mean 2418 on each tire at GVW.
With 3520 rated capacity and 2418 actual weight, that's 1102 reserve per tire. That's roughly 31% reserve capacity on "new" tires. Given the 10% aging degredation of the polyester cording, at the end of 3 years the tires would be carrying roughly their "maximum aged rating". So, just for grins, at 6 years (60% reduction) the tires would have a capacity of 3520x.40=1408 pounds each. That's 5632 max tire capacity with 9671 on the axles.
Maxxis may have a limited warranty against some loss, but from the 10% age reduction, I'd be concerned at the end of the 3rd year from the date of manufacture.
Plus, to "add insult to injury", this is included in the Maxxis warranty CW posted: "(C) Loss of time, inconvenience, loss of use of the trailer, costs of towing or transportation, and/or incidental or consequential damages of any type or nature. Vehicle or trailer damage is not covered."
The two paragraphs above this one are filled with "outs" for the tire company to use to avoid payment for damages. While Maxxis is an "outstanding company" with a superb reputation, who knows what their financial status and policy toward paying for trailer damage will be "if the worst happens in 6 years"...
Just doing the math and knowing the weights we carry, I'd start worrying about tire safety and reliability about the 3 year mark when the tires are "age rated" at the trailer's GVW. I don't think I'd trust 6 years with any brand ST tire in the LRE category.

John, I think that one of the big differences that sets the Maxxis tires apart from some of the other tires out there is the tire construction for the tread. The Maxxis 8008 employs 3 polyester cords, two steel cords, and two nylon cords. I'm not sure how this construction for the tread affects the "guesstimate" of 10% of tire derating per year, but it may just throw that guesstimate off by some amount. Just some food for thought.
And it probably goes without saying (but I'll say it anyway) maintaining the proper inflation in the tires as well as limiting the UV exposure time, goes a long way to preserving the tire longevity.

Just purchased my first new RV and can't wait to get my TPMS system put on it from my previous RV. Thought when I decided to purchase I would end up taking RV to tire shop and having good rubber put on but found one with good rubber already installed. Have Sailuns on my new one, don't anticipate having issues but better safe than sorry. No one knows how fast or hard RVs are driven or towed when being delivered!
