I am going to replace my stock 20 inch chrome rims that came with my 2009 Ram Sport 1500. I want to purchase the 20 inch KMC XD Rockstar and put them on my stock 20 inch tires....I don't know the specific size.. I have been told two different things. I would like an exact fit. I believe its 20x8.5 with 5x5.5???with 5x139.7??? ---don't know if this is right or what it means. I don't know the off sets and spacing.. Could someone please let me know the exact specifications so i can order them.

Also I emailed Mr wheel deal--he had the best price...has anyone ever used him..weird web site..no phone #'s all emails...

 

check on the net.... good luck..

 

Both bolt patterns are the same and both will work. It just depends on the website. As for the rest, I'll let someone smarter than I chime in.

 

ok there are 2 different off sets you could get for those rims

1. +10 (20 x 8.5)
2. -24 (20 x 10)

To my knowledge the rockstars only come in 20 x 8.5 and a 20 x 10.
If i was you i would get the 20 x 10 BUT im not so sure they will fit on the stock tires (i might be wrong)

Now if you get the 20 x 10 they will stick out of the fenders about 3 or so inches

Your going to need a bolt pattern of 5 x 5.5
