If the old guy called them suicide rims, that's probably what you've got. Tubeless wheel designs are much different than tube type wheel designs. Tubeless designs are always in half sizes (17.5, 19.5, 22.5) and will in truck applications always have what's called a 15° rim lip profile and a drop center. The tube type rims have what's called a 5° rim lip and will have either a flat center or a semi-drop center profile. I'm gonna try to link in my Photobucket page that shows a side by side diagram of the two. If it doesn't work, you can probably find it in the Accuride catalog. The reason the 20" tube type and 22.5" tubeless have the same outside tire diameter is the different lip profile and drop center. Stu Wheel Profile Comparison [Reply]  [No Email]
