Nitto tires...
Well, when i first mounted the rims/tires.. i had a hard time finding a place that did the correct job.... i went to pepboys and they mounted/balanced them for me, put them on the truck and away i went... i drove from pensacola florida to louisiana and there was a terrible shake in the car.... and i thought, oh my god, did i just make a mistake.... well, i brought it to sears in lafayette louisiana, my home, and they popped the tires off, rebalanced them and still, shook, but not as bad.... so i just didn't know what to do.... sears showed me how the rim wabbled on the machine even without a tire.... so i thougth that maybe it was a bad rim.... only until i went to desert rat, on a trip from pensacola to los angeles to ship my truck to hawaii where i am now, did i get the problem fixed... the guys there , rebalanced them and they ran perfect....
guess i just chaulk it up to experience with the machine helps....
as far as the tires grip... i think they hug to road alot more than stock tires, they are 31.4" tall, and 11" wide... they grip perfect in sand, and mud... ice i dont' know, but i lived in icey weather before, i swear bye blizzak ice tires, from my days in japan ... those things grip like no other...
overall, i like the tires alot... the tread wear is better than bfg's... so... i was sold...plus they look great...
