Rim size?

I'm up-sizing my wheels and wondered what to get. I'm going to 33x12.5x15 but should I spend the extra for the 10" rims or would the 8" be ok? How fat of a tire can an 8" hold?

15x8 is fine. Most jeepers run them with 33x12.5's

either is fine. 15x10 gives a wider stance, 8" wide wheel will hold the bead better for aired down wheeling, but i've had both and never had a problem with either. choose what looks best to you. i like the stance of the 10 wheel in most cases

I found some M/T Classic II that only come in 15X8. The backspacing is 3 5/16 with an offset of 30mm. Will that be enough for my 08 "X" with a Skyjacker 2" lift?

2" lift w/ 33's is gonna be pretty tight, but then again i don't know much about the sizes on jk though. sounds a little tight to me, but never seen one first hand..

The stock JK rubi comes stock with 32's.

JK with 4'' lift can run 37'' tires.

I got the 23S pckg on my "X" which came with the 17" tires (255 75 17) which are a little over a 32" tire. The part I'm concerned with is the shock/frame rubbing. All the parts websites say the a JK only requires a 2" lift to run 33x12.5, but since I'm new at this I figured I would poll some experts out there. Thanks for all your inputs. I'm slowly figuring out this 4WD thing as I go.

jeeze, i kinda thought about that as i was writing that. back in the old days a 2" lift wouldn't clear a whole lot. then i thought about the rubi. but does an x have smaller suspension? i didn't catch what jk he's got.

No height differance in the coils between the X and rubi model, same senerio as a TJ // x or rubi... Just a different coil rate.

Yes you can run 33's with a 2'' lift on the JK.

BUT>>>>>>>>> will a 15'' wheel clear your brake rotors/calipers???

There are reasons that the newer cars/trucks/jeeps run larger wheels from the factory.

Some 15" wheels don't.
You might want to get 16's instead. Or just run 255/85-16 mudders on your stock wheels... ...it's about the most popular overlander tire right now...


And you don't need any lift at all to run 33's unless you're going to disconnect the swaybar. You just need the correct backspacing.

A lot of 15" wheels will not clear the JK calipers or will reqire some grinding of the caliper to fit. If you are not sure of the fit and order them, it would be a good idea to test fit the wheel before you mount a tire to it. Most places won't let you return wheels once they have had a tire mounted.
