Maximum gradability:
The term "maximum gradability" denotes the steepest
grade a fully equipped vehicle can negotiate in low gear while
carrying its rated payload.
In line with standard practice, the surmountable grade is denoted by percent of slope or grade percentage. This grade percentage is the ration of the vertical rise to the horizontal distance traveled. Thus if there is a rise of 53 ft and a horizontal distance of 100 feet, the ration is 53/100, which is expressed as 53 per cent.
Tire Information:
CMPs were originally built using "Run-Flat" tires which
due to their thick sidewalls could run for 50 miles without air.
Thus most trucks with this type of tires had no provision for
spare tires. This type of tire used a great deal of rubber and
weighed substantially more than standard pneumatic cross country
tires. The 10.50x20 run-flat tires weighed nearly 100 lbs per
tire assembly more than current 11.00x20 tires.
