lol just bragging rights among my gladiator buddys....You started a thread to discuss a .6 inch difference in tire height...lol?? Nobody cares about that part...40" consideration is more aimed at weight, type, ply, etc...
Running a 40x13.50R17 vs. a 40x15.50R20 offers more substance and debate...imo.
Everyone with 40s is in the same group.lol just bragging rights among my gladiator buddys....
