Hey guys stupid question.....

[Darwin]

I just picked up a 2010 bright silver metallic JKU on wednesday (traded in the KJ for it) bone stock for now....nothing fancy just auto transmission and a hard top only had 30 miles on her when I pulled it off the lot. My question is the 225/75/R16's are going to be the first thing to go before the fall/winter.....Does anyone know for sure or can anyone hazard a guess would 265/75/R16's fit without having to do an assload of trimming and what not? I was running that size in the Hankook dynapro mt's on the old liberty and I was kindda hoping they would fit on the JK without a lift seeing as how I have to hold off on MAJOR mods for a while

I wanna say with 265 you do have to do some trimming! I think the rock rails and somthing else (if you have rock rails)! Ill see if i can find the thread!

Up to 33 inch tires fit stock. You can't flex for crap, but doesn't require trimming.

Maybe AZKJ will chime in, he was running 33's on the stock suspension for awhile.

There is a JK forum through Pirate 4x4, JKOwners. I bet you can find everything you ever wanted to know over there.

That size is roughly a 32 x 10 which will fit fine with no rubbing, even flexed.
255/75s are an optional factory size and measure in at 32 x 10.

You can fit 33's on a stock JK without a lift. Extreemly minor rubbing at full turn. Now with a 2 1/2" lift you won't rub. (33" duratracks on a stock 07 JK before the lift went on)

The 265/75-16 measure 31.64" x 10.43" x 7.82" sidewall. They will fit with no issues at all on the stock JKs.

33's will fit a stock JK X IF you trim the plastic air dam behind the bumper and don't mind a little rubbing on the back fenders whenever you hit a bump on or off the trail. The exception being is if you have the longer shocks that come with the towing package OR a Rubicon. There are three different shock sizes that Jeep puts on the JK. Mine came with the crappy short ones. For a few $$$ more I got the RE 2.0" lift and longer monotube shocks.

I have a '08 JK X. I'm running 285/75-16 BFG M/T KM2 (wanna be 33's... 32.83" x 11.22" x 8.41" sidewalls. As mentioned above, they fit, but they rubbed, especially when loaded down with trail and camping gear.

I went with a Rubicon Express 2.0" coil spacer lift with their longer monotube shocks. The front and rear bumpers are now 24" off the ground, the rock rails are 20" and the diff clears by a little over 13".

Why Mopar lift etc? They are expensive. FYI... mods in them self do not void a warranty even tho some dealers may try to intimidate you into believing that crap. The only way mods void the warranty is if the specific mod has a "direct effect" on the issue you are having.

Another reason why I went with a 2" lift... anything over 3" and you start getting into drive shaft issues as well as beefing up other parts, extending brake lines etc etc. With the way my JK is set up, it is more than capable for the medium to slightly difficult trails I run.

Before the 2.0" lift and 285/75-16 tires...

Flex with the stock Rubi BFG M/T KM 32" x 17" tires/wheels not disconnected and no lift (no rubbing issues)...

One thing to seriously consider if you go with larger tires and go off road... re gear. I stalled on every rock that even looked at my Jeep with the stock 3.21 gears (a KJ comes stock with 3.73... go figure). I just had Yukon 4.56 gears installed. The difference is as different as day and night on the highway and the trail.

The old 3.21 gears on the left and 4.56 on the right...

You'll find a lot of anwers to your JK guestions HERE. A lot of people don't like the owner and how he runs his forum, but you'll find a lot of stuff.
