Done every 5,000 miles or so, a tire rotation is the act of moving tires around your car, truck or SUV so the tires wear evenly. Some vehicles have “staggered” tire sizes, meaning that the fronts are smaller than the rears. In this case, they can only be rotated from left to right (or vice versa). Some high-performance tires shouldn’t be rotated at all, since they’re made to turn in one direction only (usually indicated by an arrow on the tire’s sidewall). As always, consult your owner’s manual for more information.
