Just taking delivery of our new AY M4, we wanted to share 18" 513M wheel weights to use as a reference:
Wheels: 18x9.0 Front (ET29) 18x10.0 Rear (ET40), Style 513M
Tires: 18": Michelin Super Sport: 255/40-18, 275/40-18
Front: 44.00lb w/ tire
Rear: 48.25lb w/ tire
According to TireRack data, tires weigh in at 25lbs for 255s and 27lbs on 275s.
Front: Style 513M, (no tire): 19.0lbs
Rear: Style 513M, (no tire): 21.25lbs
