TyRE INFO-TIRE ROTATION INSTRUCTIONS
Tires should be serviced periodically following the rotation patterns provided in the vehicle's owner's manual or as established by the industry. Using tire rotation as a preventative maintenance will equalize front-to-rear and side-to-side wear rates while enhancing wear quality and pattern noise. Any minor 1/32" to 2/32" differences in front-to-rear tread depth between tires that might be encountered immediately after periodic tire rotations at 3,000-5,000 mile intervals won't upset the vehicle's hydroplaning balance and should not preclude rotating tires. For that matter, any differences in wear rates actually indicate that tire rotations should be done more frequently.
"When done at the recommended times, [tire rotation] can preserve balanced handling and traction and even out tire wear. Tire rotation can even provide performance advantages."
