I am going to have to replace my Toyo M608z 245/70R19.5 tires soon, It looks like I will get about 60,000 miles out of them at 11,000gvw. I am looking for input on how long your 19.5 tires lasted, and...
Passenger car tires have very thin sides, with single fabric layer. 19.5 commercial tires have like 1/2" sides with multi fabric in it. They suppose to last 10 years, but depends on UV damage you should check them after 7 years. Trailer tires have extra wax in them, to protect them for long periods from UV, but that's theory.
