When to Replace Your Tires

Replace now if you see

• Tread at 2/32" or flush with the wear bars (penny test)
• Bulges, blisters or cuts in the sidewall
• Exposed cords or steel belts
• A puncture in the sidewall or shoulder, or a tread puncture bigger than a repairable size (USTMA guidance is up to 1/4")

Plan to replace soon if

• Tread is at 4/32" or less, especially if you drive in rain or snow
• The tire is 6+ years old, or has visible cracking (DOT date code)
• There's uneven wear, which can also mean alignment or pressure issues
• There's new vibration or noise that a balance doesn't fix

Replace in pairs or sets

Many makers recommend replacing all four tires on AWD vehicles, or keeping tread depths closely matched. Check your owner's manual. If you're only replacing two, tire makers generally advise putting the newer tires on the rear axle.
