Summer road trip season is one of the best times of year, but it's also one of the most demanding periods for your tires. Long hours at highway speeds, heavy loads from luggage and passengers, and scorching pavement temperatures all push your tires harder than typical daily driving. A few minutes of preparation before departure can prevent a breakdown that ruins your vacation.
Start with a thorough visual inspection. Look for uneven wear patterns that indicate alignment or suspension issues. Check for cracks in the sidewall, bulges, or embedded objects like nails or screws. Any of these warrant a visit to a tire shop before your trip. Next, verify your tread depth using a tread depth gauge or the penny test. Insert a penny into the tread with Lincoln's head facing down. If you can see the top of his head, your tread is below 2/32 of an inch and the tire is legally worn out. For summer road trip safety, we recommend replacing tires once they reach 4/32 of an inch, as shallow tread significantly reduces wet-weather grip.
Tire pressure is your most critical check. Use a reliable gauge to measure each tire's pressure when the tires are cold, meaning the car hasn't been driven for at least three hours. Compare the readings to the recommended pressure on your driver's door placard, not the maximum pressure stamped on the tire sidewall. Inflate or deflate as needed to match the specification. If your vehicle will be carrying a heavier load than usual, your owner's manual may recommend slightly higher pressures for full-load conditions. Properly inflated tires run cooler, wear more evenly, and deliver better fuel economy, all of which matter on a long road trip.
Don't forget to check the spare tire. Nothing is worse than having a flat and discovering your spare is also flat. Many newer vehicles have switched to tire repair kits instead of spares, so verify what your car includes and make sure the kit is complete and the sealant hasn't expired. Consider packing a portable tire inflator, which can be a lifesaver on remote stretches of highway.
