For 1990-2009 cars only
Lead is the deviation of the vehicle from a straight path, on a level road, without hand pressure on the steering wheel.
Lead is usually caused by the following:
| • | Tire construction. Refer to Tire and Wheel Specifications in Tires and Wheels. |
| • | Uneven brake adjustment. Refer to Brake System Diagnosis in Hydraulic Brakes. |
| • | Wheel alignment. |
The way in which a tire is built may produce lead. Rear tires will not cause lead.
