Your trailer tires may not get the same attention as the ones on your tow vehicle, but they play a starring role in every adventure. Keeping them in good shape isn’t just about safety—it’s about avoiding the heart-stopping sound of a blowout on the highway. Trust us, there’s no fun in wrestling a trailer with a shredded tire.

At Redman’s RV & Trailer Sales & Service, we’re here to make sure your tires are always road-ready. Let’s talk about the key steps to trailer tire maintenance and how to keep those wheels rolling smoothly.

Trailer Tires Have an Expiration Date

Here’s something many trailer owners overlook: tires aren’t just about tread—they have a shelf life.

• The 5-Year Rule: Trailer tires are designed to last about five years, even if the tread still looks good. Over time, the rubber breaks down due to age, UV exposure, and weather conditions.
• How to check the age: Look for the DOT number on the tire’s sidewall. The last four digits indicate the week and year the tire was manufactured. For example, “2318” means the tire was made in the 23rd week of 2018. If your tires are approaching their fifth birthday, it’s time for new ones.

Check for Sidewall Cracks

Cracks in the sidewall are like wrinkles on your tire—they tell a story, but this isn’t one you want to ignore.

• Inspect regularly: Look for cracks, splits, or bulges. These are signs the rubber is deteriorating and the tire may fail soon.
• Don’t take chances: If you see significant cracking, replace the tire. A blowout on the road isn’t worth the risk.

Inspect the Tread

While trailer tires don’t wear down as quickly as car tires (because they don’t steer or brake), they still need regular checks.

• What to look for: Uneven wear, bald spots, or tread depth less than 2/32 of an inch. Uneven wear might also indicate alignment or suspension issues.
• Use the penny test: Stick a penny into the tread with Lincoln’s head facing down. If you can see all of Abe’s head, it’s time for new tires.

Proper Inflation Is Key

Underinflated or overinflated tires are a recipe for disaster. Maintaining the correct pressure ensures your trailer handles properly and your tires wear evenly.

• Check tire pressure regularly, especially before long trips. Use a quality tire gauge to measure the PSI (pounds per square inch).
• Follow the manufacturer’s recommendations: The correct PSI is usually listed on the sidewall of the tire or in your trailer’s manual.
• Cold tires only: Always check tire pressure when the tires are cold, as heat can cause readings to vary.

Pro Tips for Trailer Tire Maintenance

• Invest in tire covers: Protect your tires from UV damage when your trailer is parked.
• Rotate your tires: If your trailer has tandem axles, rotating the tires regularly can promote even wear.
• Don’t overload: Exceeding your tire’s load capacity can lead to premature wear or failure. Check the load rating on the sidewall and stay within limits.
