Tread Widths—Triples

Tread is measured between center of tires.

Approximate tread range for each tire size is shown in the following chart. Additional spacings can be obtained by slight adjustment of inner and dual wheels. Steering stops required on all triple tread.

NOTE: See Observing Tread Width Limitations in this section.
