HELP,  I have a 2000 Wrangler with no lift, will 31" tires fit on 15 x 7 rims without any modifications or lift and stay inside the fender flares?  Help!  

I've run 3 set's of 31's on my '97 TJ(though I have 8" wide rims).  They fit fine.  They will rub a little on full turn, but it is a small adjustment of the steering stops to fix this.

The next question ... will you be offroading it?  If so, and you plan to disconnect your front swaybar ... they'll hit the fenders.  I beleive a small 1-2" spacer lift will fix this.

As for the flares, 31x10.5's will tuck under Sahara flares just fine, and just barely poke out under Sport flares.

Hope it helps.

No off roading!  Just ant to fill the wheel wells without sticking out too far.  As for the off set on the rims, what will keep it under the sport flares?

Your stock rims should be fine!  As I said above, even with the sport flares, they just barely stick out.

I'm sure you could find a tire shop that would do a test fit for you.

Here's a description of adjusting the wheel stops I grabbed off the web:

The steering stops are located on the brake backing plates (in front of the

axle tubes).  The easiest way to adjust them is to raise the front of your

Jeep off the ground and (ignition off and steering wheel unlocked) turn the

tire (using the tire, not the steering wheel) all the way to the left or

right and see how much space there is between the head of the stop bolt and

the flat spot where it is supposed to hit.  Remove the stop bolt/nut combo

(they're tack welded together) and put enough washers under the nut to

bring the bolt up enough to eliminate the rubbing.  Some trial and error is

usually required, but 1 or 2 washers will usually work for 31x10.50s on a

TJ, or 30x9.50s on a YJ OR for whatever size tires I had on my CJ7. :-)

Repeat for the other side.
