Maximum tire size on 2010 JK 2DR
 
Hey everyone, When I bought my 2010 JK Wrangler this past April it came stock, no Sahara or Rubicon package. Currently I have 225/75/16 tires with factory rims. I'm looking into getting different tires and rims. I've read a lot of postings about what tires and wheels people bought. However, I hear many people talking about 31x10.50 tires. Seeing that this is a different layout than mine above, I am guessing 31x10.50 is metric and my numbers are non-metric?

So my question is, without doing any body or suspension lifts or any other modifications to my Jeep, what tire and rim size could I go up to? I looked at tirerack.com and they are showing all measurements in the format my tires are in. I checked a conversion chart and show 31x10.50/16 = 267/71/16. Is this the biggest I can go w/o any mods? Can I go wider on the tires and rims, fatter look?

I should add that my Jeep is used mainly on the roads for work, however I would like the ability to hit the trails every once in a while so don't want to lose too much MPGs out of it.

Find a rim style that you like and make sure it has 4.5 or less of backspacing if you plan to lift in the future. I've seen people on here or the jeep forum say they fit a 33 inch tire with no rubbing. If you go any bigger you will rub. Mine came with 32 inch tires from the factory and wheeled it a couple time without rubbing and no mods. I'm sure a few more people will chime in that have more experience than I do. Everyone on here has good knowledge of jeeps so this place is pretty nice.

32's as beakaroo mentioned is about as big as you can go on stock wheels with no suspension mods. Other wise you'll rub at full lock or offroad. Also as he mentioned, there are ways around the rubbing problems, with different wheels and adjustments to the steering stops...

It's actually just the opposite. Here is a website that will help with the tire sizes. Car / SUV / Van / Light Truck Tire Calculations

When I look at tirerack.com and other tire websites, all of their tires are listed in the format of 225/75/16 styles, what size would 31x10.50 tires be listed as?

See the link above.... Most tire sites have a converter for English to metric....

225/75/16 are 29" tires on 16" wheels. 245/75/16 are 30" tires on the same. 255/75/17 are 32" tires on 17" wheels (stock S sport package and rubicon size). 285/70/17 are almost 33" tires on 17" wheels with a width of 70.

These are the most popular sizes for a stock JK with no mods. There are others but these are pretty common.

Okay cool, I thought I was on the right track, just wanted clarification. So in looking for tires and wheels, I've gone to a few sites and there doesn't seem to be a lot of choices for rims for 15" which I was surprised since I read a few other posts that stated this was the most popular size for people without performing any mods. When I place in the bolt pattern 5 on 4.5 and diameter of 15", I only get about 10-12 choices of rims for black alloy. Should I consider going up a size on the rim and tire? What websites do you all use for looking at or buying your rims and tires? I've gone to the following sites for rims, which I am looking for alloy wheels:

Wheel Finder-RH3
Wheel Finder - Truck & Jeep Wheels, Off Road Wheels, Cast & Steel Wheels-RH3
Jeep Alloy Wheels - Quadratec (limited on filtering)

Whoa!!!!! You have a JK, bolt pattern is 5 on 5, and most 15" wheels don't have the offset to accommodate your brakes..... You can do it, but you must get the right wheels. Spend some time reading the JK forum and you'll learn what works and what doesn't without grinding the calipers. The majority of JK owners go to a 16" wheel/tire combo.... Most 15" tires come in truck (English) sizes, that's probably why you're having problems finding them...

Thx for the clarification InfernoGirl, I thought I had read that JKs have 5 on 4.5, guess I misread something somewhere. I'll go back to the links I checked out and see what they come up with for 5 on 5 with 16" diameter.

ESP 12-15-2010 12:04 PM

Yes, your JK is definitely a 5 on 5 bolt pattern. They make adapters for 4.5 to work on 5 but I wouldn't recommend them. Just stick to a safe match that works.

Another question along the same line. I want to replace the 255 70 18 Bridgestones with Michelin LTX MS tires. The only size that's close is 265 70s. Anybody know if they'll work without scrubbing anything?

Depends on backspacing. I think on stock wheels those would rub.

Dogzilla 12-15-2010 06:19 PM

The Michelins are apparently 1/2 inch wider, and 1/2 inch taller. Should that make a difference in scrubbing?

obrienmd2 12-15-2010 07:18 PM

Okay so I found what I am interested in. Let me know if these are compatible together please. Do you think they will look good together? Trying to keep the costs down somewhat and want to stay stock on the Jeep, no lift

1/4" inside and up shouldn't make much diff.....

That's what I'm thinking/hoping. Thanks.
