Radial Tire Lead/Pull Correction. Chevrolet Metro 2000

For 1990-2009 cars

Lead/pull is the deviation of the vehicle from a straight path on a level road with no pressure on the steering wheel. Lead is usually caused by the following conditions:

• | Off center belt

• | Uneven brake assemblies

• | Improper tire and wheel alignment in the front tires (rear tires will not cause lead)

Tire construction can be a cause of lead in a vehicle. An example of this is placement of the belt. Off center belts on radial tires can cause the tire to develop a side force while rolling straight down the road, and the tire will tend to roll like a cone.

Use the lead/pull correction table in order to verify that improper tire and wheel alignment is not mistaken for tire lead.
