Refer to the sticker on the driver's side doorjamb or your owner's manual to determine the recommended tire pressure for your 2018 Honda Civic Coupe. It's important to check your tire pressure when the tires are cold, as the pressure increases as the tires heat up from driving. In addition to checking your tire pressure, it's also important to rotate your tires regularly. Tire rotation involves moving the tires from one position on the vehicle to another to ensure even wear. The recommended tire rotation interval is typically every 6,000 to 8,000 miles, but you should consult your owner's manual for specific recommendations. Tire rotation helps to distribute wear more evenly across all four tires, extending their lifespan and improving your vehicle's handling and stability. Finally, it's essential to get your wheels aligned if you notice any pulling or uneven wear patterns. Wheel alignment ensures that all four wheels are pointing in the correct direction relative to each other and to the vehicle's frame. Misaligned wheels can cause your tires to wear out unevenly and prematurely, and they can also affect your vehicle's handling and stability. If you notice that your car is pulling to one side or that your tires are wearing out unevenly, take your car to a qualified mechanic for a wheel alignment. By following these tire maintenance tips, you can extend the life of your tires, improve your vehicle's performance, and ensure your safety on the road.
