a lot of people mess up their axles by rock crawling. Getting a 35" tires spinning free and then all of a sudden something may happen to get it to catch traction. Then have fun getting home
I seen it a lot on wranglers with dana 35s running bigger than 35s.
I myself am on 36.77x14 nitto terras with 3.55s and am seeing better mileage and performance than I did on my mud terrain 35x12.50s
