Spacers Really Needed
Gents,
I'm getting my 35's Saturday and will be putting them on my JK (Mods below). They are going on the stock rubi wheels. I dont get crazy offroad as this is my daily ride. Do I really need spacers? Will I have all kinds of tire rub if I dont get spacers? or just minor rub when turning full wheel?

WHEELS & TIRES
Q: What is the biggest size tire I can fit on my stock Jeep JK Wrangler?
A: The largest tire size that the factory recommends is a 255/75R17 (which comes standard on Rubicon models) or a 32x10.50. However, there are many Jeep JK Wrangler owners who are currently running as big as 285/70R17 or 33x10.50's with little to no rubbing issues.
Q: What is the biggest size tire that I can I fit with a 2.5" Budget Boost?
A: 33" without any problems and 35" tires with only minor rubbing at a full flex. Depending on how wide your tires are, you may experience some rubbing at a full turn especially if you did not install an adjustable front track bar and/or are still running factory wheels which have 6.25" of back spacing.
Q: What is the biggest size tire that I can fit with a 3" lift?
A: 35" tires and depending on what lift kit you have, you may still experience some minor rubbing up front at a full flex and when turning.
Q: What is the biggest size tire that I can fit with a 4" Lift?
A: 37" tires but you will need to trim the rear corner of the rocker pinch seam and you may still experience some minor rubbing at a full flex.
Q: Will 15" Wheels Fit on my JK?
A: Most steel ones will fit without any problems and depending on the thickness of the wheel most aluminum ones will as well. The only thing you really need to make sure is that the wheel clears the brake calipers.

Q: What back spacing will I need on my wheels in order to clear 12.50 wide tires?
A: I would recommend that you do not exceed 4.75" of back spacing and even at that, you may still have some minor rubbing up front at a full turn. Also, I would recommend that you do not go any less than 3.75" as anything less would cause your tires to stick out very far past the fender flares. Any back spacing within this range should work out great.
