Will the MB Rocker wheel from Discount in 16x8 work on our trucks? I got Discount to meet Costco's price on BFG A/T 10 ply LRE but I need 8" wheels and these are pretty cheap.

I have MB's from Discount in that size. They are Overdrives, IIRC, not Rockers, though. They fit fine. Little trimming done up front, mostly on drivers side, for rubbing.

I do wish they were tucked in just a little more, though. They do throw stuff up the sides of the truck. I had to put on some mud flaps to help combat that.

Yeah I don't quite understand the backspacing on wheels but I guess on an 8" wheel it is best to be around 4.5"???? And I certainly don't mind trimming and cranking.

The 4.5" is ideal for a lift though.......
