4" lift w/stock rims & bigger tires?
 
I want to keep my factory rims, which are 15x8, and put bigger tires to go with a 4" lift. I want 33s but would be happy with 32s. The problem is how narrow the tires would be if I kept all specs the same except the tire height. Can I put 33x12.5x15 on my existing rims? I am getting sooooo many different opinions from people, but none of them owns a Jeep! Some say I have to get different rims to have fat tires, others say I don't...please help. BTW: the change is purely cosmetic, not for offroad function at all.

You have to use spacers on stock wheels for 12.5" tires. If you stay with a 10.5" tire you'll be fine. The stockers have a large backspace which is what causes the most issue, not the height of the tire. Stock wheels have 5 or 5.5" bs, depending on the wheel, you need 4" or less to use a 12.5" tire.

Because the factory rims have such a large back spacing, you are limited to 33x10.5x15's


Infernogirl beat me to it.

Hmm. You mention staying with a 10.5, but stock is 9.5; I am trying to avoid the tires looking like "pizza cutters" as one person put it. :confused:

Skinnier tires are better in the snow also.

33x10.5 ain't no pizza cutter.

I am so pleasantly surprised by the quick, polite responses. Thank you everyone. Now, who wants to PM me RE: lift kits? I know I want 4", but what brand? Don't forget, not for function, just for looks....for now....until we FINALLY move to Utah!

In response to your PM, I have to agree that 33x12.50 tires would be too wide for your factory wheels. That size tire would be fine on aftermarket wheels that have less backspacing which means the wheel is spaced further out of the wheel well.

So far as what 4" lift is concerned, that is more about your budget than anything else. Going to 4" and big tires isn't cheap because then you have to start factoring added costs for a beefed up steering system to handle the bigger tires and the SYE kit and CV driveshaft strongly recommended for 4" and taller lifts to stop (cure) the major shaft vibrations 4" and taller lifts cause. :)
