Otr Tire Truck Specification Example for Courier Fleets: Heavy Duty
Otr Tire Truck Specification Example for Courier Fleets: Heavy Duty
This is a worked specification for otr tire truck in a heavy duty programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The heavy duty version exists because the duty cycle on courier fleets is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a fitment that looked right on paper and failed on the bench.
