I have a 2007 rubi... situation is I have a 2.5 teraflex econo lift with the standard rubicon rims and tires. I have the money now for tires only...so what is the biggest and best size tire I can fit on the standard rubicon rims?

 

On stock wheels without spacers, your going to be limited on width.

I have 33x12.5-17's on my stockers with a 2" BB. Height wise they would have been fine & I may even have gotten away with 35's as far as height, but the width would have caused rubbage without the spacers.

Lots of people with that combo you have, i am sure someone else can be more precise for you.

 

You'll need wheel spacers if you want to go bigger using the stock Rubicon wheels. A set of 4 Spidertrax 1.5" aluminum wheel spacers will run you about $200. A set of 5 steelies with less backspacing than stock wheels will run you about $300. Either way, you need to push out those wheels so you don't rub on your suspension components. If you do that, you can run 35s with a 2.5" lift and maybe get some rubbing on your fenders at full turn while fully stuffed - no big deal.

Hope this helps.

 

Thanks for the great advice....

 

If you off-road, don't buy the wheel spacers; buy the steelies, and you will save your wheel bearings

 

I agree!

(I think black steelies look better, too! )

 

What would be the correct size on the black steelies? Getting really fired up to do this now and learning a lot in the process!. Thanks again to everyone who has responded so far... it's been a great help

 

The difference in the stock vs. aftermarket backspacing is what causes additional stress on wheel bearings. If your stock wheels with good spacers (hub-centric on both sides) have the exact same backspacing as an aftermarket wheel, then the additional stress on the wheel bearing will be the same.

 

Yeah.... What joe said! I've got spidertrax 1.5" on my rig and I play pretty hard 3 or 4 weekends outta the month. They're all fine. Just had them checked about a week ago.

Either way, you'll need to decrease the amount of backspacing. Either via aftermarket wheel or a QUALITY spacer like the ones offered by TF or Spidertrax. Happy Wheelin'!

 

You can get new aluminum alloy wheels for a little more than steelies I think, and they come with center caps and lug nuts usually. By the time you are done it is not that much more for a lighter/nicer wheel. It has been a little while since I priced this stuff though.
