Tires are one of the most critical components on your truck or trailer — they affect safety, fuel efficiency, and your bottom line. But knowing when to replace tires and how to get the most mileage out of them isn’t always obvious. Here’s everything you need to know to keep your rigs rolling safely and economically.

How Many Miles Can Truck and Trailer Tires Last?

Heavy-duty truck tires typically last 50,000 to 70,000 miles, but this varies based on factors like load, driving conditions, and maintenance. Trailer tires often wear differently depending on the weight they carry and road conditions, sometimes lasting less than truck tires.

Signs It’s Time to Replace Your Tires

• Tread Depth is Low
  The legal minimum tread depth for truck tires is usually around 4/32 of an inch on the front axle and 2/32 on other axles. Use a tread gauge or the penny test to check.
• Visible Damage or Cracks
  Cuts, cracks, bulges, or sidewall damage mean your tire is compromised and should be replaced immediately.
• Uneven Wear Patterns
  This could indicate alignment problems, suspension issues, or improper inflation. Uneven wear can lead to premature tire failure.
• Frequent Air Pressure Loss
  If your tires lose air pressure quickly, it may be a sign of leaks or damage.

Tips to Extend the Life of Your Truck and Trailer Tires

1. Regular Tire Inspections
   Check tires for tread depth, damage, and pressure at least weekly. Catching problems early can save you money.
2. Maintain Proper Inflation
   Under- or over-inflated tires wear unevenly and can fail prematurely. Use a reliable gauge and follow manufacturer specs.
3. Rotate Tires Periodically
   Rotating tires ensures even wear. Work with your mechanic to set a schedule based on your mileage and load.
4. Wheel Alignment and Suspension Checks
   Misalignment causes uneven wear and affects handling. Have your alignment checked during routine maintenance.
5. Drive Smoothly
   Aggressive braking, fast turns, and rapid acceleration can all shorten tire life.
