Tire Alignment Balance Rotation
SUSPENSION, WHEEL ALIGNMENT AND BALANCE AND ROTATE YOUR TIRES.
Tire/wheel balance is important for vehicle ride & stability. Tires are manufactured to close tolerances for roundness & shape, but as a tire wears, the tire's mass may become unevenly distributed, & the original rim/tire balance may be affected.
There are two approaches to wheel balancing on-car balancing & off-car balancing. Various types of balancing equipment are used & include static & dynamic balancers for off-car work & mechanical & electronic balancers for on-car work. Wheel weights added to the inside or outside of the rim correct imbalance as indicated by balancing equipment. While balancing may seem a relatively simple operation, care must be taken to eliminate imbalance, because even a minor imbalance contributes to wheel wobble & poor ride & handling characteristics.
Tires should be checked monthly for signs of irregular wear in both tread & shoulder areas. Irregular wear may indicate underinflation or tire damage, or the need for a wheel alignment or suspension repairs. Also, when a replacement set of tires is fitted to a car, a wheel alignment is mandatory.
There are three elements involved in wheel alignment, each affecting the vehicle's performance. These angles are referred to as caster, camber & toe.
CASTER is the angle between a vertical line & a line drawn through the center of the ball joints (steering axis) when the vehicle is viewed from the side.
Improper caster can cause hard steering, increased road shock, reduced straight line stability & cause the vehicle to pull to one side or the other. Positive caster helps in maintaining directional control of the vehicle, tends to return the vehicle to straight-ahead position when cornering, & helps compensate for the crown on a road. Most cars are engineered with positive caster.
NOTE: Irregular wear or excessive wear in any area of the tread may indicate tire damage & the need for expert inspection.
When the remaining tread depth measures - 2/32", these tires are considered to be legally worn out & must be replaced.
Tires should be rotated at frequent & regular intervals. Tires can be rotated conveniently during a regular oil change, which for most vehicles occurs every 5,000 to 7,500 miles. Dunlop recommends rotation every 6,000 miles or less for optimum benefit.
There are many tire rotation patterns. Your Dunlop dealer will rotate tires in accordance with the pattern required for your vehicle.
