I have a Texas Trail JT 2021 regeared to 4.88 and arb lockers front and rear with stock knuckles and axle shafts. Metal Cloak FUll Armor underneath and Clayton Overland Plus 3.5 lift. I am currently running 35 in tires with no issue. It's time for a new set and I was thinking of moving up to 37's. Clearance won't be an issue with the clayton lift and I do plan to do some wheeling as I am getting ready to head out to Washington State for a wedding and on the way back I am going to hit Rim Rocker from Moab to Colorado and maybe some other trails in Colorado. Imogene Pass maybe? Would the change to 37's be something to be worried about? I'm a cautious driver but this is my daily vehicle and I'll be pulling a small trailer as well so there is some concern about breaking down on trail particularly in Colorado after doing Rim Rocker which looks to be fairly tame. The 37's would be the Patagonia Milestar MT02's and are about 12lbs heavier than the Pro Comp Gladiators I have installed now. Rims are 12.50 x 17.
