Ford Police Interceptor Sedan Uneven tire wear Inspection at your home or office.

How it's done:

A mechanic will first inspect the tires to determine the wear and get a better idea of what might have been going wrong. If the mechanic suspects that the tire is under or over inflated, he or she will use a tire pressure gauge to determine the exact pressure inside the tire. The mechanic will then compare that reading to the one on the outside of the tire. Depending on the measurement, the mechanic may have to inflate or let some air out of the tires. Wear in the center of the tire will most likely mean the mechanic will be letting out air, while wear on the edges mean the mechanic will most likely be adding air.

If the mechanic suspects that the vehicle is out of alignment, they will have to adjust suspension components that may have been affected by hitting a pothole or curb. Suspension components may also begin to fail over time, causing the vehicle to come out of alignment. While aligning your vehicle, the mechanic will also see if suspension components need to be replaced. The mechanic will adjust each side of the vehicle so that the tires are flat on the road and not at an angle.

If the wear on the tires is more significant at the front, the tires may need to be rotated. The mechanic will remove each tire and rotate it from front to back and side to side.

In all repairs the mechanic will also check the tread on the tires to make sure that they are still good. Tires that have low tread will not be as effective as new tires. When replacing tires, it is important to have tires of the same brand and size to ensure that they all wear evenly.
