Another Tire Blowout
I bought Jayco Jay Feather hybrid new in 2014. It had 4 Towmax ST185/80R13 tires from the factory. Since owning the camper I've blown out 3 tires. Took the camper out for the first time this year last...

So, you are stating that trailer tires are the same quality as a P or LT tire?
There is NO WAY quality is the same between the tires.
I agree wholeheartedly. An ST tire is not rated to go on ANY drive wheel or steering wheel. It might last a couple hundred miles on a car or truck, but I doubt it. The sidewalls are thin and super soft. The only reason I can think of why an inferior tire is made for trailers is it costs less. Less to make and less to the consumer.
I had a 5vr that GVWRd at 11500 with 15 inch ST on it. Blowouts constantly. 4 failed on one trip and were new. Couldn't find a 15 LT in the size/load rating. Had the shop check on 2 occasions for alignment, brake, bearing issues and it checked ok. I crawled under myself and checked alignment and for bent axles and all was fine. No one could tell me why my tires failed. The only suggestion beyond IDK was an old experience RVr said "springs" after telling my tale. He said they were under rated for my trailer weight and the tires had to absorb all the stress. But I digress.
After getting rid of that POS, I got a 14,500 GVWR 5vr with 16" LTs. I towed that thing 5000+ miles across AZ at 70-75 MPH and never a failure. Will not buy ST tires unless I end up with a trailer that has 17.5" G rated.
