| Definition:
Forward or backward tilt of king pin or Measured in degrees positive or negative. |
Influence
on Vehicle Handling:
Too little causes high-speed instability
and Too much causes hard steering, excessive road shock, and shimmy through the steering wheel. |
Influence
on Tire Wear:
Usually not a factor in tire wear. |
||||
|
||||||
| Definition:
Inward or outward tilt of
wheel at the top. Measured in degrees positive or negative. |
Influence
on Vehicle Handling:
Excessive camber (negative or positive) will cause vehicle to pull to the side with greatest variance.
|
Influence
on Tire Wear:
|

|
||||||
| Definition:
Amount that front of wheels is closer together than rear of wheels. For radial tires, toe should be as close to "0" as possible when vehicle is running. Measured in inches. |
Influence
on Vehicle Handling:
May cause vehicle to
track improperly and
|

|
||||||
| Definition:
Inward tile of spindle
support arm Directional control angle
measured in degrees that spindle support center line |
Influence
on Vehicle Handling:
Non-adjustable angle
that, with camber, controls "scrub radius" to minimize |
Influence
on Tire Wear:
Rapid tire wear can result from mounting new wheels with different offset that may increase scrub radius by moving tire footprint outside projected pivot point. |
||||
|
||||||
| Definition:
Amount that front wheels tow out during turns. Ideal angle reduces tire scrubbing. Measured in degrees.
|
Influence
on Vehicle Handling:
Does not influence vehicle handling qualities.
