what size rims to get

[dustin g]

I am bumping up my tire size to 33" but my current factory rims wont cut it anymore. I'm looking at 33 x 10.5 x 15 or 33 x 12.5 x 15. I just don't know rim ratios to tire width. I've been told 15 x 8 rims will hold the 10.5 but what about 12.5?

You can get the 12.5 on to the 8 inch rim.The tire changer may be mad at you for a few days but it will work.Really helps if you air down.Kind of acts like a bead lock.

I have 33X12.5X15 and I run a 15X8 rim. I run them at about 26 pounds of air.

Same, but I run mine at 30. I've had no problems at all.

Why would they be mad? I mounted my tires with no troubles at all.

Thanks for all the info. Next question is backspacing. I currently use factory Jeep rims with 1.5" spacers. I want to eliminate the spacers and add a little more spacing if possible. Any ideas? What is the factory backspacing?
