To equalize tread wear, it is recommended that the tires be rotated every 10,000 Km or sooner if irregular wear develops. During rotation, check the tires for correct balance.
When rotating tires, check for uneven wear and damage. Abnormal wear is usually caused by incorrect tire pressure, improper wheel alignment, out-of –balance wheels, severe braking or severe cornering. Look for bumps or bulges in the tread or side of tire.
Replace the tire if you find either of these conditions. Replace the tire if fabric or cord is visible. After rotation, be sure to bring the front and rear tire pressures to specification and check lug nut tightness.
