Can someone tell me what wheels are on my truck, the backspacing, and offset? Also, is the offset and backspacing correct for this truck? The truck is a 2000 F-350 CCLB with 6" Rough Country lift. The PO installed the lift new and bought the current tires {37x13.50x18 Nitto Mud Grappler's} and wheels used on Craigslist. I'm wondering if the rims are correct b/c the tires rub the leaf spring at full lock. I thought a 6" lift should clear the 37's, but maybe the wheels are backspaced or offset incorrectly, or it's just the big side cleats on the Grapplers causing it.
The tires will need to be replaced soon and I've always liked the black RockStar's, so if the rims aren't right I might just go with them and either 35x12.50's or the metric equivalent of 36x13 {315-70R18} Toyo Open Country MT's.
