The front and rear tires wear at different rates. Rotating them swaps their positions so they wear evenly and last longer.
A common interval is every 5,000 to 8,000 miles (8,000 to 13,000 km), which is often the same visit as an oil change. Check your manual: some cars with different-sized front and rear tires, or directional tires, rotate differently or not at all.
Evenly worn tires grip better, and a rotation costs far less than replacing tires early. Some tire warranties require you to prove you rotated them.
Ask for the tire pressures to be set, and have the tread and sidewalls checked for damage.
Yes, and often more carefully. Uneven tire wear can strain an all-wheel-drive system, so follow the manual.
No. Rotation swaps the tires between positions. Alignment adjusts the angles of the wheels. Both help tires wear well.
General guidance, not professional advice. Intervals are typical ranges and vary by car, so check your owner’s manual and ask a qualified mechanic if you’re unsure.
