3-axle tire wear.

Thanks for all the info. The tires say to run a max 80psi cold. I run 75psi cold. The TH is a 2013 Attitude 39TSG 3-axle. We made it down to Johnson Valley but, we were 15 miles from home when the rt rr tire blew. Come to find out when they replaced the rear axle and Trail America tires. They installed 235/85 r16, E-load. The other 4 tires are 235/80 R16 E-load. The tires they installed only had 860 miles on them before it blew. Trail America is made by a Co. called Treadit. They were very helpful. They are sending 3 new tires out. Once i get the tires installed the TH is heading down to Eclipse in Riverside. Not to happy with Eclipse. And maybe its just MY TH but, we've had it for a year. Used it 8 times and every time we use it it ends up in the shop. Not once have we been able to come home from a trip and just put it away issue free!! I hope by taking it to Eclipse i wont have any more issues!! LOL. We've towed it approx 5400 miles, 1444 mi of that was to take it in for repairs!! Sorry for the rambling. Had to vent.
