Signs You May Need to Rotate your Tires
Uneven tire wear
Uneven tire wear is the most common sign that you may need your tires rotated. You can check this by measuring the tread depth in multiple spots on each tire. If the measurements are drastically differently, your tires are wearing unevenly. Tread feathering is one of the most common wear pattern when tires are not properly rotated. You can feel feathering by running your hand along the tire tread. The tread blocks will have rounded edges on one side and sharp edges on the other. It is important to keep in mind that rotating your tires will not correct wear problems due to worn mechanical parts, incorrect inflation pressures or alignment problems.
Uneven front to rear tread wear
While each tire can wear unevenly, tires on the front axle can also wear differently than tires on the rear axle. Regularly rotating them allows the tires to serve in both front and rear positions which help to even out the wear. Although regular rotation can help with uneven wear, different tread wear patterns can help diagnosis other problems you may be having.
Tire noise and vibration
When tires wear unevenly, it causes increased road noise and vibrations. While vibrations can be felt in other parts of the car, it is most commonly noticed in the steering wheel.
