RPM Wheels - Chrome 20 inch rims from RPM @ Wheelstudio.com - The all chrome RMP M-512 is a five spoke design with several styling ques. The spokes have a raised center that remains the same width as the spoke flares to meet the deep lip. Each spoke has a pair of simulated rivets for a multi-piece look and has a foot that stays raised over the lip to the edge of the rim. The chrome center cap keeps the face of the wheel from becoming too busy, and matches the mirror-like finish of the rest of the wheel.
