SUBJECT: ROAD FORCE BALANCER WITH STRAIGHTTRACK REQUIREMENT
As sales and service volumes increase, it is important that KMA keep pace with the expectations of our customers. This includes having the proper equipment and the trained personnel to diagnose and correct vehicle drift or pull. Understanding the causes of vehicle drift and pull is imperative when servicing these vehicles.
A vehicle's tires can have significant effect on its drift or pull for the
following reasons:
^ Ply steer- Ply steer is an inherent characteristic in a tire which results in a lateral force as the tire rolls. Rotating the tires from side to side may aid in cancelling out the effects of ply steer and can aid in diagnosing a ply steer concern.
^ Conicity- Tire conicity refers to the shape of the tire and how cone shaped it is. This can influence vehicle drift or pull. Conicity can be present in a new tire due to manufacturing, or in a used tire due to camber wear. Rotating tires may reduce a vehicle pull concern due to tire conicity.
Analysis has shown that many vehicle tracking concerns could have been corrected by using a Hunter Road Force Balancer with StraightTrak. The StraightTrak feature measures the lateral force of a tire due to ply steer, conicity, and other issues which may contribute to vehicle tracking. Using the Road Force Balancer is a real benefit to correct tracking concerns.
For these reasons, the Hunter Road Force Wheel Balancer with StraightTrak is now ESSENTIAL equipment for all Kia Dealerships.
Requirements
To ensure quality vehicle repair, all Kia Dealers are required to have a Hunter Road Force Wheel Balancer with StraightTrak on the dealership premises. Dealers must have this equipment in use and in proper operating order by February 28, 2013.
