    Default Tire Width on New Wrangler

    Anyone fit a 35 12.5 17 tire under a JK on the factory wheels? I am curious as to how much they will rub. Plenty of height just not sure if the width is to much.

    Any lift on the Jeep? Oh, and yes they will rub without spacers behind the stock wheels. You need wheels with about 4.5" of backspace.

    I think he is more worried about hitting on a horizontal plane than on a vertical plane.
    Stock tires are 10" wide. Anything 10.5" wide or wider will start hitting.
    A friend of mine went from the original 255's to 285's(11.2"w) making them almost an inch and a quarter wider(5/8ths on both sides) and had to go with more negative offset to prevent rubbing on the inside of the tire. But it all depends on how much rubbing you are comfortable with and if you adjust your steering stops ;)
    Traction, articulation, and gearing make a good off-road rig. Just a big lift, wide mud tires, and a winch simply do not.

    Good to know, I didn't think I could pull it off. I was told not to do spacers by the tech here at work. Said it will cause more problems than anything. New wheels it is :)

    The tech is full of crap. Spidertrax spacers work great and don't cause any problems. I wouldn't use a cheap set but Spidertrax are great (when installed properly).

    I myself would never use spacers but I don't like running offset wheels either, so I don't count ;) However that being said, they do make good quality spacers for those that want and need, and Dave is correct in saying "when properly installed"

    Both ZR2's have rear wheel spacers and been trouble-free for years.YMMV

    I run these with Spidertrax and they still rub on the control arms. I have my steering stops set so they just touch. If I had it to do over I would buy better wheels. I got a complete set of new (take offs) 17" JK Mopar wheels in August, currently I have 2 that have sections of the rim torn off already.

    I am starting to look for 17" wheels again, and no I don't want to buy yours.

    What size spacers are you running?

    I know this is an old thread but I have a similar question for a 2018 JLUR. I'm putting on a 2" lift and want to put 35" tires on my stock JL 17" wheels. Is it safe/adviseable to put 315/70/17 tires on a stock wheel that is 7.5" wide? (please note I didn't ask about tire selection since I don't want to start a squabble.)

    Thanks!

    Way too much tire for that size rim.

    8.5 is the recommended min size rim according to Summit.
