Default 3.75 or 4" backspacing

97TJ 4.0L, AX15 5speed , 231 t-case, Hp Dana30 front (out of 89 XJ), Dana44 rear w/ 4.56 gears, 4" Rough Country lift, Advanced Adapters Slip yoke eliminator and driveshaft, 6" bushwacker pocket style fender flares.

The 31" tires we were running up until now were on 15X8 with 3.75 BS.

I will be running either 33X12.5X15 Kumho KL71 (just released this year haven't even found them for sale anywhere) or Cooper discoverer STT (also just recently released).

we would like to get 15X10 wheels.

i don't know if i should get 3.75 or 4" backspacing. the wheels my wife wants only come in 15X10 w/4" BS. I think she should stay with the 3.75 BS since i'm afraid she'll rub with the 4".

i tried to provided as much info as possible above so you know what i'm dealing with.

If the 4 inch BS doesn't work, you can always adjust the steering stops to prevent rubbing turning lock to lock. I honestly don't think 1/4" is going to make a huge difference.

4" will be fine.

Remember with 10" wheels that extra 2" is added on the outside of the rim.
