Blackdog speaks the truth. The LTBs are nice tires offroad but think about it. Do you really want to get half the life of a BFG to save maybe 25-50 bucks per tire??
Consider this: I bought my 32 bfgs from a guy in Sac. He had driven them for over a year, on the road only. i ran them for another year then sold them to my friend Adam who ran them on his truck for another year and a half. Then, I bought them back (they were on 15x10 black rims), gave the rims to my GF and gave the tires to my friend Wade's dad, who is still using them on his nissan. so that is....about 5 years on one set of tires, who are now onto their fourth owner. they still have 10-15% tread left on em.
So think about it....why have to reinvest in tires every year?
