If your car's wheels are out of alignment, your tires will wear unevenly, which can lead to early tire replacement.
Similarly, tires and wheels that are out of balance
don't just cause annoying vibration. Uneven tread wear may also result, further reducing your ride's comfort and leading to early tire replacement.
Even if your car is properly aligned, tires still need to be rotated
for optimal wear performance. Rotation counteracts the uneven wear characteristics of each wheel position on the vehicle.
