These are Firestone Winterforce tires on 17" ford fusion rims. They have been used on my Genesis Grand Touring (non brembo) the fronts are 225/50r17 and the backs are 225/55r17. traction control works perfectly with this staggered setup. Tread life is at least 90% left. They have not been abused and have not been used in temps over 40 deg F. Local pickup only around berkley, mi 48072.
