After owning a tundra on 35s my ranger on 295 65 18 procomp mt 2 get 18 mpg . Also have a set of 275 65 18 bfg avg 20 mpg . My truck was stock for 4 days.
Yes on locker and tow package. Yes it does go off roading . It really comes down to the alignment. The shop that aligned it first it did rub. Took it to my shop i use they got it right. They dont believe in spec they believe in perfection. They also work on my big rig.
