I have a BRAND NEW set of four Mercedes Benz Factory Original 2003 SL500 18" AMG Wheels & Pirelli PZero Ultra High-Performance Z Rated Tires. These came off my SL55 as I upgraded to Brabus Monoblock VI rims. If you are in the Boston area, I would sell them to you for $2,000. Will fit any 2003 SL. This is how they looked when I picked up the car last week.
Size: Wheels measure 18" x 8.5" in front and 18"x9.5 in back front offset is 30 mm, back offset is 33 mm , Tires are Pirelli Pzero 255/40/ZR18 Front, and Back 285/35/18. Bolt Pattern: 5-112
