35's on "stock" rims

I have a 2014 JKU Willy's and love the black rims & I'd like to keep them when I go bigger! Does anyone know the biggest tire that will fit on a stock 17 x 7.5 rim? I guess I am looking for something like a 35x10.5x17 or so. Please help.

The most common 35" dia tire size has a section width of 12.5" which is too wide of a tire for a 7.5" rim if you are going by the tire manufacturer's recommendations. With that being said, many Jeep owners have installed these tires on factory rims and never reported having any problems. Going with a tire that wide with the factory wheels requires adding wheel spacers.

The size you stated would be considered a pizza cutter tire, and if you can find a tire manufactured in that size, you may have no issues at all. Sourcing the tire may be a little more difficult, tirerack.com does not carry anything in that size.

I've got 315/75/17s (34") on my stock rims with 1.5" spacers and a 2.5" lift. I removed my air dam. If you want to keep it you will have to do some trimming. I chalked my tires and the tread will wear nice and even at 30 psi. Here is a pic of the setup.

I'm glad you posted this as I'm looking to buy a WW. I like the black Rubi rims and want to keep them, but I'd like to increase the tire size. I'm planning on installing a teraflex leveling kit. Does anyone know how limited I'll be with tire size. I wasthinking I can run a 33/34 with wheel spacers. Do I have to go 1.5" spacers or can I go 1.25" or 1"? The backspacing phenomenon baffles me lol.

The quadratec website has simple "lift kit advisor" built into it. There appears to be kits ranging from $300 to $2000 that will allow for the fitment of 35's. The backspacing issue is due to the increased treadwidth associated with typical 35's. Assuming most 35's are roughly 2 inches wider that stock, we need to move the center of our rims at least 1" out to make sure there is no rubbing. To me, the simple answer is lift allows for taller tires, and backspacing allows for wider ones.
