What tire size for 15x10's with 3.5 in backspace for Cherokee Sport

I just picked up some wheels for cheap. They are 15x10 with approx 3-4 in of backspace. My Cherokee is a 1995 stock 2wd with no lift. The wheels have 31x10.5x50r15's on them. I know those are too big but I would like to use the wheels.

Any ideas?

Thanks

Since you have a 2wd, just mount them and the back and see how they work.

31x10.5x50r15's are really not that big. Originals are 28 inches in diameter.

For the front, you could use a LT235/75-15 or a 30 incher on the stock rim or an 8 inch wide.
