Bruce from Florida writes: “I have a 2004 Ford Mustang Cobra convertible and I can’t find tires that are the same size as what came on it in 2004. They are not worn out but I have been told that I should replace them because they are 16 years old. The size is 245/45X 17 and I am not able to locate these tires or at least some at a reasonable cost. Is there another size I could use? Any suggestions would be appreciated.”
Halderman: Thanks for writing. You are wise to be shopping for replacement tires. Vehicle manufacturers Ford, Nissan, Mazda and Mercedes-Benz recommend replacing tires after six years regardless of tread depth. Tire manufacturers Michelin and Continental recommends that tires that are 10 years old be replaced. Therefore, according to the industry standards, your Mustang is definitely in need of new shoes.
