Hi
I found a couple of rims that I like. The specs are 20x10 5x5.5 +0
and 17x8.5 5x5.5 -6mm. My ram has a 2.5 leveling kit on it. Will these rims fit and what is the largest tire. Any answers would be great. Does anyone know the stock backspacing/offset.

 

I think the stockers are 20x9, but not sure on the backspacing.

 

Thanks for your response. I misslead you I have the stocks on the truck of 17x8. I am just too lazy to pull them off and measure the backspacing myself. I just thought someone would know the answer off the top of their head. Thanks for your time though!!!

 

If you go to tirerack.com or discounttire.com, it will show you what wheels are for your vehicle. It will also give you +1 sizing to put larger ones on.
I believe the 17s are 5x5.5. Check out those sites....I forget the exact vernacular...
