Im getting a 2"1/2 lift with wheels 15"x10" and 32"x11.5" tires. Will this all work out good?

15x10.... Do you want to make any turns or just go straight?

Forget about the wheels.......... (if you can)

Whether or not it works will depend on the offset of the wheels used with the tires.

Probably not without rubbing.

how about if i go with 15x8 wheels

15X8 is a more reasonable choice, especially if you are just going with a 32X11.50 tire. With a 10" rim your rims will be more subject to trail hazards because you will have less of a "bubble effect" with the tire sidewall. Even if your getting the steel rockcrawler rims damage to the rim that effect your bead seat could occur. The 10" rims are really more for the 13"-15" wide tires.

15x7 x8 x?? it doesn't matter, its which rims and the numbers that go with it (offset/backspacing) You can have a bad fit with all the sizes.
You'll have to post the brand of rims and numbers for anyone to say if it will work or not.

True but you'll have an easier time fitting an 8" rim than a 10" rim. Myself and another person in our club both run the Calmini 3" suspension lift and a body lift with 33X12.50 tires. I have a 2" BL and he has a 3" BL. I rund 8" rims and only have rubbing issues at full compression. He has the 10" rims and rubs contantly.
