Correct Wheel Back Spacing!!!!!!

[ERICSRANGER]

CAN ANYONE HELP ME WITH THE CORRECT WHEEL BACK SPACING, I HAVE A 94 EXT CAB RANGER WITH A SIX INCH SYSTEM W/STOCK RAD. ARMS. WOULD LIKE TO PUT 12.50 WIDE TIRES ON MAYBE 10 INCH RIMS OR SHOULD I GO WITH EIGHTS... BACK SPACING IS THE QUESTION????

The Ranger comes stock with 4" backspacing. My Cragar's have 3.75" back spacing. You may want to stay with a 0 offset or about 5" backspacing with 10" rims.

Please turn off the caps.

For 12.50 wide tires, either 8" or 10" wheels is fine.
8" wheels are preferred if you air down on the trail much (holds the bead better).

3.75" BS on 8" wheels, 4.5" on the 10s are the standard sizes available that work well.
