Tire Lead

"Lead" is the deviation of the vehicle from a straight path on a level road without pressure on the steering wheel.

Lead is usually caused by:
^ Incorrect wheel alignment
^ Uneven brake adjustment
^ Uneven or incorrect tire inflation pressures
^ Faulty tire construction





A defective tire built with the radial belts closer to one side of the tire than the other may cause the tire to be slightly cone shaped. This will cause the tire to pull the vehicle in one direction or the other.

If the vehicle pulls and there is no abnormal tread wear, use the following steps to determine the defective tire.

1. Rotate the front two wheel and tire assemblies.
2. Road test the vehicle. If the vehicle pulls in the opposite direction, one of the front tires is at fault.
3. For models with unidirectional tires, rotate the front wheel and tire assemblies back to their original position.
4. Rotate one of the front wheel and tire assemblies with its corresponding rear wheel and tire assembly on the same side of the vehicle.
5. If the condition is corrected, replace the tire that was rotated to the rear. If the condition does not change, replace the front tire on the opposite side of the vehicle.
