35 x 12.5's on my Sport Max Tow w/ no lift (yet). No rubbing, and rides and handles almost better than stock, feeling more stable than before.
The diesels are come with 3.73 gearing. According to my official youtube watching research 37" tires work great without regearing and still use 8th gear plenty on the Diesel JLUR so far. I had 37" on my JLUR with 4.10 gearing and lost most use of the 8th gear with any type of wind. It still ran around great though and pulled my boat. This engine change is moving from 260 lb ft of torque to 440 lb ft of torque. My 37" STT pro tires on my rubicon would still just touch the fenders with swaybar disconnected with a 2.5" dynatrac lift and bump stop extensions. On some tougher trails at Moab the tread did catch a front fender liner and pop the plastic push rivet out. Easy fix and the combination was perfect for a low center of gravity but plenty of tire for way more than I had planned to do on the trails. A heat gun can help reshape some of the inner fender to a more desireable shape with less contact if needed.The diesels were announced with taller gearing, which already changes things to fit the diesel. So a major change in tire size still might need a gearing change, depending on your usage and terrain.
My stock Rubi tires measured out to just under 33 actual, on the truck at normal pressure.
Should have shot the photo straight on. This angle makes the grey one look bigger than actually is. Not really a fair comparisonSo maybe people will stop asking about it . lol
Mine(37s) with a Mopar 2” lift and 1” spacer. The BFG K02s are small 37s, they measure about 35.6”.
The black one has Nitto G2s 35s with a 1” spacer.
Both on 17” Fuel Rebel wheels.
Gears cost anywhere from $1600-2400, depending on the shop. Reinforce axle? Best lift? Depends on what you’re gonna do.Week#2 of my 2021 Gladiator Rubicon being built. Any rough estimate 4.88 regearing, tires and best lift. Do I need to reinforce the axle, brakes heavy duty enough? What about u joint angle?
