Tires: lifespan, maintenance and replacement

Typical lifespan: 25,000–50,000 miles.

Maintenance schedule

• Check tire pressure — Monthly
• Rotate tires — Every 5,000–7,500 miles
• Measure tread depth with a gauge across the tire — Monthly
• Wheel alignment check — Annually

Signs it needs replacing

• Tread depth at or below 2/32 inch
• Visible cords or steel belts
• Uneven wear patterns
• Cracks in sidewall
• Vibration at highway speeds
• Tires reaching the vehicle or tire manufacturer’s age limit, even if tread remains

Tips

Check the DOT date code and the manufacturer’s inspection/replacement age guidance; no universal six-year limit fits every tire. Use the door-placard pressure measured cold, not the sidewall maximum. Wet traction decreases before the 2/32-inch wear limit; damage or exposed cords means stop using the tire.
