i want to put 285 70 17 on my stock 08 rubicon. i test fitted them and they rubbed. if i was to put a teratrek leveling kit in would those tires now fit??

 

What did they rub? Fenders? Just trim or get leveling kit. Sway bars? You need more backspacing on the tire.

 

Here's my 2 cents worth...

Stock wheels -- they probably rub at full turn; Adjust the steering stops and possibly trim/remove the front air dam. See link in signature below for a picture of the steering stops. A leveling kit won't fix it.

Aftermarket wheels with more back-spacing-- they probably rub at full articulation on the fenders; Add bump stops, modify fenders, and similar. A typical leveling kit won't fix it, but it the rub will happen less often (because of more up-travel before hitting the bump stops).

 

Typically on stock wheels you need to run wheel spacers for those tires, and a leveling kit would help also. Even then, you'd probably rub your fenders if you disconnect the sway bar and flex.

 

are wheel spacers risky? i heard the led to potential problems

 

Good spacers are the same as wheels with a similar resulting backspacing. Either will put some greater leverage/load on ball joints, etc.

 

I just cut the "wings" off the front air dam and put two small washers on my steering stops. My 275/70R18's are the same as a 33X11. I have zero issues at full flex and full lock. I have a very mild 2" coil spring lift.
