OTR Tires Help Make the Grade 

What do you call a county engineer with a motor grader? A highway department. There is a lot of truth to this old joke. Motor graders are used for everything from the construction of roads to the maintenance of them in both municipal and civil applications, as well as in industries like mining. Consequently, motor graders are also commonly called road graders. Ensuring this valuable piece of equipment makes the grade are its tires.
