Notes: 1. Nominal gross axle weight rating is based on minimum axle mounting centers
of 38 inch and a maximum
track width
of 73 in.
2. Track widths
are nominal and may vary with wheel equipment.
3. All ratings are for standard track width
housings. Track increase over standard is produced by wheel
outset
.
4. Site Travel
: 5 miles per hour maximum speed with liftable axles raised. This condition should not exceed
5% of the total operating miles of the vehicle.

manufacturer may also limit the rating of the tire based on the load per tire and the pressure, which could
be less than the approved axle rating.
