14x5.5 SBP “Performance wheels”
They are factory 14 x 5.5“ steel wheels. It is stamped on the inside of the wheel. They measure 5 1/2 inches inside the bead seat. Google it and you will see what I am talking about. Typical a body steel wheels were 14“ x 4.5”. Performance cars such as GTS and formula S and Cudas got the 5.5” wide steel wheel. Do you have a set?
