Is it wise to put 32x10.5x15 tires on a stock jeep TJ? If not, how about 31x10.5x15? I like the look, and I am not looking to get a lift anytime soon, but my tires will need replacing in a couple of months and id like to start shopping asap. I heard 33x10.5x15 were bad, but I would like to go as tall and as wide as possible with a stock 2000 Jeep Wrangler Sahara. would adding wheel spacers possible help?
You can go as large as 33x10.5. My friend had a 99 4cyl with them on stock suspension and drove like this for several years until he got a small budget boost (2" coil spacers). If you go offroad it'll smack into pretty much everything and you can adjust your steering stops to compensate for the extra width by adding a few washers. I'm unsure if anyone makes a 32x10.5r15, though so it might be 31's or 33's. Anyways, here's a pic of my buddy's Jeep with 33x10.5s on stock wheels.
That's not death wobble, the roads in PA are just *that* bad.
Before I decided to lift mine I ran 31's on the stock rims without a problem. As far as I know, the Sahara's came stock with 30x9.50's. You can check the V.I.N. tag in the drivers door jamb to verify your stock tire size.
Mine came to me with 32" BFGs, stock Rubicon rims and stock suspension. The tires rub on sharp turns and do occasionally hit the wheel wells on the trails. For what I do, I can't really say its a problem that needs immediate attention. 33's would likely be annoying without a lift.
It all depends on what you do with the Jeep. biffgnar is correct, assuming that you often make full use of your articulation. If you don't, like most people, then you will have fewer issues with larger tires.
Functionality aside, I will also admit that I do like the look of big tires stuffed into the wheel wells at stock height. However, I also like things that work properly.
