Sad but true. Keystone will provide Original Equipment tires that meet the very minimum required. For instance, the 2016 wide body 298FWRL models’ specs indicate the trailer is equipped with 5200# axles and de-rated by Keystone to 5080# - legally - which allowed them to fit it with ST225/75R15D tires rated at 2540# @ 65 PSI. Why they would not spend a few $$$ more for the LRE tires is beyond me.

With a trailer fitted like that it is very unlikely the OE tires would have lasted more than a year with a normal load, correct tire inflation pressures and speeds under 65 MPH.

Notes: All RV trailer tires are fitted to GAWR. With RV trailers there is no requirement/regulation for the trailer manufacturer to provide tires with load capacity reserves. The RMA recommends load capacity reserves to be at least +12%.

On average, a 1 PSI loss of recommended tire inflation pressure equates to a 1.7% loss of load capacity for that tire. It’s not a big deal with automotive vehicles because they have some reserves to fall back on. For people hauling fully loaded RV trailers it is a big deal. Do you know what kind of load capacity reserves your trailer tires are providing?

The LRE is rated for 2830# at 80 PSI. Check your rims to make sure they will handle the extra PSI. Without using PSI above 65 PSI you gain nothing with the LRE. Also, shop around. A lot of the new tires have higher speed ratings. Look for a service description like this 117/112L, The "L" is a speed letter for 75 MPH. They might also have "M" or "N" for higher speed ratings.

Note: Service descriptions are allowed on ST & LT tires but they are not the official load indicator, that distinction for those tires is the Load Range letter.

Id stick with the rims you've got. Dump the "China Bombs" and put on some new tires. You got very lucky to have a blowout that didn't tear anything up. Slow down and enjoy the ride.

Heres the problem......everything is made in china. Goodyear are "mostly" made in america. What does that mean? Goodyear doesnt make or maybe I didn't see ST 225/75R15 E load range tire, only a D. Most tires are made over seas in american companies, is that what u mean?

I think most (all?) trailer tires are made overseas. I believe Maxxis are made in Thailand and Goodyear (RV) tires are back in China as far as I remember. They sent them to China, brought them back and sent them back again....if memory serves me correctly. The "china bombs" come primarily from the plants in the Shandong province. Those are the plants used to produce Trailer Kings and all of the other brands made by the parent company. From my personal experience, and many others posted on this forum and others, they make an inferior product. Most folks have had good luck with the Carlisle HD and Maxxis tires from what I've read.

I have three questions:

1) When you say Carlisle HD and Maxxis, do I assume you mean Carlisle Radial Trail HD and Maxxis M8008 ST?

Background for #2:
I somehow scuffed up the lead trailer tire on the driver side and took a small chunk out of the sidewall (a Trailer King ST205/75R14C, original to the trailer, purchased new 2 years ago). The tire on the rear axle shows no scuffing or damage. I discovered this damage while doing a tire check prior to a camping trip.

I typically travel 55 mph on the highway. Tread and condition of the other three tires looks quite good.

2) Due to the present budget, I'd like to only replace the one tire rather than all four at this time, if the consensus is that is OK to do.

3) If the answer to #2 is it is OK to replace the one tire, when it is mounted should it be the lead tire or the trailing tire (i.e., do I put it back from where it came or should I swap it with the one behind it)?

Thank you for sharing your expertise.

Sister Schack,
Replace at least that damaged tire. If you have a good spare consider putting it on as the other tire on that side. Last season I hit a curb and did the same thing on the right side. I saw no damage to the other tire on that side but I ended up having a blowout of the tire that didn't look damaged. Like you I am a conservative driver too. Travel safely.

Do at least what Tbos recommends above. You need to get that damaged tire off before you go anywhere and replace the other one on the same side with the spare....if it's any good. Look them over very carefully. They tend to destruct from the inside out. Unfortunately, replacing an RV tire one at a time in different years will probably lead to a failure at some point simply because you can't tell a "good" tire by looking at it. My recommendation, and I think most, would be to replace them all if at all possible. If not, be sure and put a note somewhere so you know what tire was replaced when so you can keep track of what's on what wheel.

I installed the Carlisle HD. Maxxis is another good tire but I don't know if they make them in your size. My problem with the Maxxis was getting them in in a timely manner before we left and they have far fewer warranty locations than Carlisle per the tire dealer (DT).

Yes, Carlisle Radial Trail HD and Maxxis M8008 ST tires are what most are referring to.

I'd figure out how to replace all 4 at the same time. DT usually always has 6 months no interest financing...

Get rid of those Trailer Kings...

If you were close, I'd give you my 3 "good" TK's.

As soon as I spotted the chunk out of the sidewall I swapped out the tire with the spare.

Wally World has the Carlisle Radial Trail HD 8 ply (the 65 psi tire) for $50 a piece, only $3 more than the 6 ply (go figure). I've spoken with the household budget director (the DW) and we'll do all four.

Thank you all for your comments and concern.

As of today I have four new, balanced, 8 ply Carlisle Radial Trail HD tires. Thank you all for your advice and comments. The old China bomb spare went back on the rear carrier - hopefully to never be used again.

Remember that part of the "preservation/aging process" for tires is being rolled under weight of the trailer, to release the oils in the rubber. Without that, tires "age faster". When you add sitting on the rear bumper under a black, gray or even a white cover, your spare will "get old before its time"... So, realize that the tires "on the trailer" will lose about 10% of capacity per year and "time out" at about 5 years, the spare, sitting on the bumper will probably lose capacity faster and age faster, approaching 15% or even more per year. So, if that spare has been on the bumper for 2 years already, that's close to the same as 3 (or more) years on the ground. Don't ignore your spare by thinking it's going to "just be there, stagnant" until you need it. Watch it closely, when you get to 3 years from the manufacturing date, start considering whether you want to risk using it, even as an emergency measure to get you to the next tire dealership.

Thinking of buying these tires. Are they made in the USA.

Until just recently there are NO ST tires that are produced in the USA. Last month Goodyear announced their new ST tire, the Endurance and said that it will be produced in the US. https://corporate.goodyear.com/en-US...iler_tire.html

To my knowledge, this is the only ST tire manufactured in the US. I haven't heard of any reports on durability, reliability or performance. It's available at Tire Rack, Wal Mart and other tire sales centers.

John. Did some reading and it seems like this is a good tire. Will look into buying as long as they ship to Canada. Thanks

What's even scarier than your China bombs are mine that size the same. The difference is my trailer is roughly 2,000 lbs heavier. I'm upgrading not only tires but wheels size to to give me much appreciated insurance when rolling at highway speeds. Wheels are on order; tires will be mounted and balanced courtesy of Discount Tire. And I didnt forget the spare. Spare tire gets a steel wheel though.

Further to the new Goodyear Endurance ST tires. Sound real good.
ST225/75R15 = 2800 load, 10 ply rating, n speed rating (87 mph).
Made in the USA. Doing research this is the ONLY ST tire not made in China or other overseas countries. Price on Tire Rack $120US. Was only introduced Jan/17 so too soon for owner feedback but Tire Rack has high praise for it.Worth checking out if looking for made in USA ST tires.
