i have an 2004 quad cab 4wd.. im getting rid of the factory 20 inch rims for some others..
ive buying some 33. 12.50s and i need to know what size rim is needed to clear the calipers and such.
any help would be great...

 

What is the complete tire size you are using? 33x12.5-?? I do not have any wheels with smaller than 17" diameter that fit your Ram, although some may exist somewhere.
