The frost heaves in the Northeast this year are awful. I had to replace two drive tires so far because the belts busted. Has anyone done anything like decreasing pressure to help soften the blows?
are you running down gravel roads a lot? Are they a closed shoulder highway tire? I have had rock drilling kill highway tired cause they allow the moisture to eat through the belts
Best thing is to slow down so the truck doesn't bounce. Also check your shocks, that could be half the problem. We had frost heaves so bad up here one year they destroyed the highway and you could only go about 20 mph.
