SERVICE INFORMATION

Because of differences in various alignment machines, different types of measurement readings exist in the field.

As a rule, Toe-in and Camber are given in angular degrees. Some alignment machines display figures for the Toe-in in fractions of an inch or decimal inches or in millimeters. The equivalent angular degrees can easily be obtained from the tables shown below.

Toe-inDegree	13 Inch Rims mm	13 Inch Rims inch	13 Inch Rims fract	14 Inch Rims mm	14 Inch Rims inch	14 Inch Rims fract	15 Inch Rims mm	15 Inch Rims inch	15 Inch Rims fract
