How often should you rotate your tires? While the answer may vary for different makes and models, a good general rule is every 5,000 to 8,000 miles.

Tires need rotation to make sure they wear evenly. Quirks in the suspension and alignment, as well as the different roles played by front and back tires, mean that they can wear unevenly over time.

To counteract uneven wear, tires are periodically rotated—usually by a professional—front to back and/or side to side. You can read your car’s owner manual or speak to a mechanic at the dealership to get precise instructions that apply to your make and model.

Other important aspects of tire maintenance include:

• Proper Inflation. Tires need to be inflated properly for your car to run properly and to avoid wear. Newer cars may have a pressure monitoring system, while older cars may require you to measure it with a gauge. Tire inflation is measured in pounds per square inch, or PSI. Correct inflation will be different on every car. To find out what your car needs, consult the owner’s manual. Some cars also have the numbers listed on the car itself, often inside the driver’s door.
• Adequate Tread Depth. Tires need enough tread to grip the road. Some tires have “wear bars” that, when flush with the tire’s treads, indicate that it’s time to replace the tire, according to the U.S. Tire Manufacturers Association. Hey also offer a simple test: “Place a penny upside down into a tread groove. If part of Lincoln’s head is covered by the tread, you’re good to go. If you can see all of his head, it’s new tire time.”
• Correct Steering Alignment. If your steering is out of alignment, causing your car to “pull” right or left, it can cause uneven wear on tires. This can happen after hitting a large pothole or other obstacle. Having your car aligned by a mechanic can fix the problem.

Most experts recommend that you inspect your tires periodically and look for problems. That includes the spare tire, which should also be maintained.

While maintaining your tires is routine, cars that require excessive maintenance can be a drain on your finances and your time. If it is time to replace your vehicle, you can get a start by pre-qualifying for auto financing, which will help you set a budget and prepare you to visit dealerships.
