TurboedMJ Posted January 29, 2023 Share Posted January 29, 2023 What is the max tire size I can run on my MJ? I believe it has a 1.5" levelling kit but that's all. For the time being, I don't intend to lift it any higher. Link to comment Share on other sites More sharing options...
TurboedMJ Posted January 29, 2023 Author Share Posted January 29, 2023 Also I'm fairly sure it has 3:07 gearing... Link to comment Share on other sites More sharing options...
majastee508 Posted January 29, 2023 Share Posted January 29, 2023 may be able to clear a 31x10.5 with the right offset wheels. however a 30x9.50 should clear without trouble Link to comment Share on other sites More sharing options...
89 MJ Posted January 29, 2023 Share Posted January 29, 2023 If the axles are original and it is a stick (based on your sig, it is), you will have 3.07 gears. You will probably want to change those. I would recommend regearing your D44 to 4.10 and finding a front axle out of a 4 cyl XJ. That will have 4.10s stock. Link to comment Share on other sites More sharing options...

That is happening sometime this summer or next winter due to finances (or it would already be done lol). Link to comment Share on other sites More sharing options...
TheDirtyJeep401 Posted January 29, 2023 Share Posted January 29, 2023 31x10.50s will fit, but with minor rubbing on the lower control arms at full lock. Most people swap lower control arms from a WJ Grand Cherokee to help with the rubbing. But other than that, they fit with no problems. Link to comment Share on other sites More sharing options...

I Ran 31x10.5 mt’s on 7inch wheels with 4 inch backspacing on 2” of lift with no rubbing of factory control arms, but once I went with tj 8” wheels they rubbed the control arms until I put some aftermarket adjustable ones in. But with 7’s and 4” backspacing 31’s shouldn’t rub Link to comment Share on other sites More sharing options...

But with 7’s and 4” backspacing 31’s shouldn’t rub Backspacing on factory Jeep wheels is 5.25", and on factory rims 31x10.50s fit and stuff inside the stock fender flares -- but rub on the lower control arms at full steering lock. On wheels with 4 inches of backspacing, you won't rub on the lower control arms but you WILL rub on the flares at full steering lock, and the tires won't fit up inside the flares and fenders when the suspension is fully compressed.

This is correct, I always ran a sway bar and my fender liners but no rubbing there, but back when my dad had the truck he trimmed my front flares to try and fit snow tires Link to comment Share on other sites More sharing options...
Eagle_SX4 Posted March 2, 2023 Share Posted March 2, 2023 I am thinking about regearing my truck to 4.10's with a 4.0, AX-15 and 31's. Any one have experience with that combo? How's it do on the highway at 75-80? Link to comment Share on other sites More sharing options...

Don’t worry about the RPMs. It’ll be happy. Link to comment Share on other sites More sharing options...

Eagle_SX4 Posted March 2, 2023 Share Posted March 2, 2023 Factory Dana 44 but my truck doesn't have the tow package or metric ton package so a rare option it seems. Link to comment Share on other sites More sharing options...
Pete M Posted March 2, 2023 Share Posted March 2, 2023 The 44 was an option unto itself too. Link to comment Share on other sites More sharing options...

My truck is the same, it's actually an Eliminator where someone ordered the D44 and LSD! Link to comment Share on other sites More sharing options...
