Kia Optima: Tire Rotation
To equalize tread wear, it is recommended that the tires be rotated every 7,500 miles (12000 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 tires showing fabric or cord. After rotation, be sure to bring the front and rear tire pressures to specification and check lug nut tightness.
Disc brake pads should be inspected for wear whenever tires are rotated.
✽ NOTICE
Radical tires having asymmetric tread patterns should only be rotated with the tire on the side of the vehicle.
Inflation Pressures

are cold. “Cold Tires” means the vehicle has not been driven for at least three
hours or driven less than one mile ...
