I'm not here to complain, since I love my OB. (It's a black LL Bean version with 6 cyl and brown leather, 17" wheels) Looks and drives great. It is on it's third set of tires and only has ~ 64,000 miles. And one of these tires is now gone. First set of B-stone REA whatever OEM's didn't last 20K miles, but no real surprise there. Next set was Yokohama Avid's chosen for good performance and high treadwear rating. Front lower control arm bushings died at 40K and ruined a pair of these before I caught and fixed it. Bought four new at that time. (possibly should have only bought two but I thought should do all 4 since it's all wheel drive) Then, right rear strut broke and caused that tire to scallop on the outside. Now I have a ruined tire and three others with about 15,000 on them. Should I buy 1, 2, or 4 new tires? Thanks for your thoughts.
