MIL-T-62735 Trucks And Truck Tractors: Modified Commercial, General Specification ForThis specification covers general requirements for the classes, models and types of modified commercial trucks indicated in the specification title above and in 1.2 below. This specification is intended only as a document to be referenced in detail specification sheets that must, as a minimum, cover detailed truck body requirements and specify the model and class required from table I.

Table 7                                          -  Chassis Friction Horsepower.   Use applicable power unit GVW (to nearest higher, 454 kg (1,000 pounds)) and the engine speed (to nearest 100 rpm) which is required for 69 km/h (43 mph) geared speed.  For GVW and engine speed beyond the range of this table, factors shall be extrapolated.

Table 8                                          -  Grade Factor.   0.75

Table 8A                                       -  Correction Factor.   Not required. Table 9                                          -  Road Factor.   0.0

6.4  Weight distribution, GAWRs and specified GVW vs GVWR.  All users of this specification are cautioned that the provisions of 3.1.7 make it highly likely that a vehicle with a gross vehicle weight rating (GVWR as opposed to the GVW specified herein) equal to the GVW specified herein will NOT meet this specification unless front and rear GVWRs are specified under 3.1.7.1 and, thus, 3.1.7 does not apply.  The Government intends to load vehicles to specified GVW with a uniformly distributed payload.  Thus, unless an ideal (and highly unlikely) relationship between the center of gravity of the load and the front and rear curb weights and GVWR exists, such a vehicle inevitably will be overloaded on the front or rear and will not conform to contract requirements.

6.5  Spare tire carriers.  Requisitioners, users and procuring activities should note that a spare tire carrier on truck tractors and dump trucks of necessity increases the wheelbase of the vehicle to what many consider an unacceptable length.  It is recommended that truck tractors be procured without a spare tire carrier, with the spare carried on or in the semitrailer the truck tractor will be pulling.  On dump trucks (and dump stakes), it is recommended that the spare be stowed on the dump truck for shipment and when needed after the dump truck is placed in use, that a wrecker be dispatched to the disabled dump truck, carrying the proper spare.
