That's with a 2.5" lift. You will have to trim bumper. I did. Also, if you have stock wheels, you need to get wheel spacers, new wheels with 4" backspacing or never make sharp turns! I love those tires though, especially for the price.

31' tires will not fit....

31" tires however will fit with a little lift, trimming, and either spacers or rims with different backspacing

now these being a wal-mart exclusive you will likely not be able to get them mounted at walmart... the policy is to only mount the size listed on your tire placard, some stores will be flexible in this by mounting a size already on the vehicle

the workaround is to bring in the wheels off the vehicle the catch is doing it this way technically voids the road hazard warranty... or you can pay for the tires then take them elsewhere for mounting

You have a 2.5' lift? I'm trying not to get a lift, or if anything just a very small cheap one. I'm On a budget they don't make those tires in size 30' unfortunately. So id need to turn the bumper and add what size spacers?

What if I put new coil springs? Lifted ones, I saw a set of rustys 2.5 coil springs on craigslist for $100 wouldn't I need to get tranny drop? To angle it? Or Is it safe to just lift it up and replace the old with those? This is my first jeep and I'm 17. I'm trying to do things the right way but I don't a lot of money obviously. I just want it a little higher for trail riding and small mud holes

You can add washers to the steering stops. It will kill your turning radius, but cheap.

Yes, I'm at 2.5. Still had to trim bumper, for spacers, 1.25 should be just fine. The only spacers I found, it was actually cheaper just to buy a set of pro comp steel wheels. Maybe you can find them cheaper! It does suck they didn't make 30's.

If you don't disco or flex you should be fine.

What did you need to do for your lift? Costs? Those rims act as spacers when you have bigger tires?

you can buy what is called a 'budget boost' for under 200$ that includes new shocks.

or don't get bigger tires.

I just put some JK wheels on my ZJ, they are 31s and they rub a little bit at full steer. And turning in reverse. You can get around town alright but I would not suggest doing any kind of real off roading.have no lift, yet but I do have my front bumper off. Im sure that does make a difference.

Edit: putting on the jk wheels required adapters tgat are 1.25" thick.
