Tire rotation, wheel alignment, and wheel balance are different services that address different wear and driving concerns. Your owner’s manual is the best source for the recommended tire-rotation interval and pattern.
Tire rotation
Rotation moves tires to different positions to help promote even wear. Some vehicles with different front and rear tire sizes may have special limitations.
Wheel alignment
Alignment adjusts wheel angles. A vehicle that pulls on a level road or shows uneven tread wear may need professional inspection.
Wheel balance
Balance corrects weight differences in the wheel-and-tire assembly. A speed-related steering-wheel or seat vibration can be a reason to have the tires inspected and balanced.
Inspect tires regularly and ask a qualified technician to identify the cause of irregular wear before replacing tires.
