NickAir, this post is regarding your earlier questions about 33 x 10.5 R15 tires fitting your TJ.
The wheel dimensions specify 15 inch, but they don't tell you what the inside dimension is on the back side of the rim to fit around the caliper. That is why buying from a place that specs the vehicle on which you are putting he rim will keep you out of trouble. Of course, any OEM wheel from a disc brake Wrangler will work. Not all 15" rims 5x4.5 with a 5" backspace will fit around the caliper.
Wilson is correct on this topic. It's possible caliper clearance is not assured just by backspacing. I should have though to mention that.
However, I do know that my American Racing Ansen Sprint 15 x 8 with 4.5 BS had plenty of clearance for stock calipers. They even cleared the Vanco Big Brakes I later put on it.
So those 15 x 8 with 4.5 BS Ansen Sprint wheels work for sure. It's likely that a 15 x 8 wheel with 5" BS would also clear everything, including calipers, but no guarantees. I guess if in doubt do a test fitting of one wheel before buying.
Probably any 15 x 8 with 4.5 BS would clear calipers. Probably any 15 x 8 with 5" BS would clear. Stock Wrangler wheels are 15 x 8 with 5.5" BS and they clear calipers. So probably not a problem. However, there is a chance Wilson's concern might apply to some wheels.
Another thing I should have mentioned is when tire clearance is tight during turns, the stock swaybar usually rubs during turns before the LCAs will rub.
I didn't have to worry about rubbing stock swaybar because I had a Currie Antirock sway bar, which has more tire clearance.
Also, I had JKS round LCAs, which offer slightly more clearance than stock rectangular LCAs.
So NickAir, please keep those things in mind.
