....I would not put an LT tire on a trailer. Had a friend loss a trailer due to an LT. Race car, tools the whole works.
Get a puncture on any tire (ST or LT), don’t realize it while runnin’ down the highway and let it run low/flat, it gets hot and separates and off you go down the Failed path. It happens.
If you have to stay with the 15" wheels , make sure your wheels are rated fro 80 pounds, and go with the maxxis E rated M8008 tires.
I agree. They have the best record of longevity in an ST.
Hey hook em they survive yes, but that is not what they are designed for. That is why they make different types of tires, I wouldn't even consider an over the road tire on an rv, same size wrong design.
Different in design, yes.
Different in sidewall flex to aid RV's cushion, true.
Different also is in how they derive their load ratings for the tire compared to LTs. Virtually no reserve capacity compared to LTs.
Created as a stronger alternative to a ‘P’ for trailer use, most radial STs (primarily made in China) are antiquated in mfr and design when compared to modern LT tires made here and in other parts of the world. Until they change their mfr process and upgrade their equipment over there, you’ll continually see substandard quality and common failures with most ST tires on the market.
If this new Carlisle can measure up to the Maxxis, that’s a good thing. I’m all for it. Only time will tell. I've got a 15" Carlisle now with new tread on it that's on a trailer that hasn't moved in 8 months. The tread just blew apart in the center of the tread, the size of a golf ball, just parked and not being used.
It's on my list to return it to Discount for another new one under CERTS warranty. In that trailer's life, I've only had to actually buy maybe 1 tire in 20 that the tread actually wore down. All the others were replaced under warranty when they failed.
My (non-RV) experience running heavy with STs on a daily basis:
Tire Lifespan was 3-6 months with one that made it 9 months once.
If it has a ‘Power, BCT, Master, Tow, Max, Guard-, Sport, or Trail’ in it’s name, I’ve tried it.
Tire deaths came from fast tread wear, punctures too large to repair, or tread separation/sidewall failure. Note: 2/3 of their miles in use were spent running unloaded.
Visits for replacement or tire repair/punctures were 1-3 times a week. After years of use, I came to know the different Discount location’s Managers all on a 1st name basis.
New wheels (some weren’t true, all were scratched) and the switch to Duravis R250 LTs…..4 months later, I had my 1st puncture repair.
30 months later, and none have failed and plenty of tread remains.
At this moment, my RV experience running STs is too traumatic to discuss.
