Well I think Rick L as others have hit this right on the head. We stated the same things as being the major USER installed cause of failure. The things you can do to help tire life are keep speed down to reduce tire heat, keep pressure at max listed to also keep heat down, keep from curbing or hurting sidewalls, check and fix mis-aligned axles in reference to center and each other also to reduce tire heat, do not overload the tire again for heat reasons and the last but a biggy do not stretch or flat spot tires from parking for long periods of time. I have a 45 foot trailer so can not put on jack stands but the smaller trailers can or move it every so often. I do not have room for a larger diameter wheel but would love to run a true truck tire. A 45 foot goose neck, 3 axle car hauler is what I pull.

I agree this is very cynical view and just me wondering..devils advocate?
In the end do what you can but I believe the industry plays the odds here. Most have limited mileage per year, most accept or expect failures and it does bring you back to store, most sell trailer or loose paperwork before failure, I wonder if the co pay or extra charges to warranty the tire about cover real costs in the end anyway.
