I am have a 2010 Jk 2 door sport. I have about 3.25 inches of lift with upgraded 18/59 coils and a 2 inch spacer. I also have chopped stock fenders. Im wondering if 33x12.50s will fill up the wheel well enough or if I should just go with 35s. The reason for my hesitation with 35s is i have the 3.21 gearing. Any input and pics are appreciated!

 

Now thats a good question, I was about to ask the same thing and then I saw this!! So here is a bump..

 

Go with the 35's. When we boughts our jeep it came with a TF 3" short arm. We just put on flat fenders from Poison Spyder and we can now clear 37's. I will try and get a picture up with the flats and 37's. I think you will regret going with 33's.

 

I would prefer the 35s but Im concerned about running them with the stock 3.21 gearing; and I wont be able to change the gearing till the warranty expires in a few years. Any thoughts?

 

are you in a 6sp or an auto? 33's will look tiny under there. I have 35s on mine 3.21s and while its not great, I seriously dont have any complaints except towing a light trailer in the mtns.

As for the warranty, are you sure it voids it? I think the lift and everything else may have already voided it so maybe that's not an issue.

 

Here are some pics of ours on 35's with a 3" Teraflex short arm and flat fenders.

 

And here are some pics with the Jeep on 37's, same 3" TF short arm and flat fenders.



I say go 35's, the 33's will look way to small for the lift and the flat fenders. IMO

 

If you regear, the only part of the warranty that should be voided would be the axle assemblies. I had 3.21's in my Jeep. I hated them with 32" tires so I regeared. Your lift, flat fenders, and 33's will not look good. Here's a pic of mine with 315/75-16's (34.7" spec, 34" on the ground) and less lift than you have.

 

I have the six speed...you? No problems on the highway?
