I found out the belts in the tire were damaged and the tire is done/wrecked and has no warranty. All 4 tires are Bridgestone Dueler A/T Revo 265/65R17 (which is the original size) and have 9/32 of an inch tread depth, new ones should have about 13/32 of an inch tread depth. I was wondering if it would be adviseable for the 4x4 drivetrain to buy 2 new tires (Bridgestone Dueler A/T Revo 265/65R17) and put them on the front axle, at the same time leaving the tires alone on the rear axle and keeping the one good tire now on the front axle as a spare tire, is a smart idea? I was wondering if the resulting 9/32 tread depth on the rear and ~13/32 tread depth on the on the front would hurt the drivetrain when driving the 4Runner in 2wd, 4wd, transfer case ingaged or center differential engaged? Thanks in advance!
