what size tires should i get??

I have a 1994 jeep YJ 4.0. With a 4 inch lift. I do a lot of trail riding and I like to disconnect my front sway bar so I need articulation.

I would go with 33 or 35 x 12.5s and trimming depending on how much you want to spend on axles, steering, ect.

I had 33x10.5x15s on my YJ w/4" lift, unlike 12.5" tires you won't need to turn the steering stops out to avoid rubbing at full lock or switch to wheels with less offset.

I ran 33x10.5x15 BFG ATs on stock 8" Gambler rims and had to adjust the steering stops. At full turn I had rubbing on the leaf springs. Now running 33x12.5x15 on ION Alloy wheels with proper backspacing and rubbing is a non-issue.

Seeing you don't have your Jeep profile filled in I'll assume you're running stock gears. 35s will be tough to run on 3.07 gears.

Glenn what is the proper backspacing for the 33x12.5x15s as I am putting in a 4.5 lift and want to run the same tires. Looking to get new rims and want to make sure that the steering is not a rub issue.

Thanks.

Did you have to adjust your gears to run with this setup? Any issues at all? I want to do the same thing as what you described. Transfer case drop? Any other info you can give would be greatly appreciated!

I didn't do a gear swap or a transfer case drop. The vibrations are there so I'm hope when I do the drop it gets rid of it. But its not that bad. Is your Jeep a 6cyl or 4cyl

For 33x12.5's you want an 8" wide rim with 3.75" backspacing.

I'm installing a 4.5" lift now and in the instructions it actually says that the lift was designed around this tire combo.

33x10.50 15 BF MTs with 4in lift on stock rims with a transfercase drop. 4.0 5speed with stock gears. I would not go over 33s without a regear. Off road I use 4low because it seems to bogdown in 4hi and on road 5th gear is worthless and never used. I had to add 3 washers to my steering stops on each side to stop rubbing
