Ok. I have been looking into it a lot lately. Im going to buy the wheels and tires I want and put them on the truck. Take out the stupid front spring spacers the PO put on the truck and then lower it 2/4.
I want to put 20's on without having to cut, bend, or weld anything. So I have read that 20's can do that on a spring 2/4 drop.

Im looking at 245/45r20 on the front and 275/40r20 on the rear. This should keep the tire heights close to the stock 235/75r15 by like 0.7% or something. (.76 front and .69 rear). So I should be looking at I think 8 inch wide front wheels and 10 inch wide rear wheels.

What offset/back spacing should I be looking at? I want the wheels as flush to the outer wheel well as possible but I want the centers to look like they are even. (Have you ever seen a german car with a wide back wheel but the centers are sunk in on the rears but the front centers are flush with the wheel well... thats gross.)

And if I am reading this correctly, the factory wheel was either a 7 or 7.5 with 0 offset, or backspacing of 4 or 4.25 inches depending if it is a 7 or 7.5 inch wheel.... is this correct?


A quick search, of eBay, it looks like a staged set of 20's comes in 8 and 10 in and ET of 0 and 6. Does this sound like it would looks right and fit correctly.

Or... I have found JD Wheels makes replica rallys. In a 20 they come by 8 and 9.5 with 4.5 and 5.25 backspacing.... is that too much backspacing ?
