Firestone Destination M/T. Mounted,balanced,valve stems= $545 OTD for 31-10.5-15.
3yrs.,60000+mi. and I've still got over 1/4" tread. But driving habits play a big role in tire life,obviously. I drive like a sane person and don't burn the lugs off my mud tires at every stop sign like I see so many around here do.
Besides the fact that my truck probably wouldn't do it!
