Once a tire begins to break down, it becomes more likely to fail in the form of a tread separation–often at highway speeds, when the failure is most likely to cause catastrophic injuries or death.For most tires, this expiration date should be six years from the date of manufacture. If you drive a vehicle every day, you'll probably wear out the tread in less than five. So your tires will probably need to be replaced before the tread wears out.Maybe it's cracks from the sun or maybe it's sitting too long with too little air in them.Date codes Every tire has this code on the sidewall.It gives the date that the tire was manufactured but it doesn't just spell it out right.This code is sometimes referred to as a serial number. The code starts with the DOT designation, followed by a series of letters and numbers.Have you ever asked yourself, “how old are my tires?

A tire's plant of origin and date of manufacture are located on each tire.

When your tires hit fives year in age, it's time to think about replacing them.
