TIRES BY TYPE OF VEHICLE
(TRA Codes E-1, E-2, E-3 and E-4)
Since dump trucks must travel under heavy load at high speeds, over relatively long distances, tires for dump trucks must have high heat and wear resistance. Sometimes high resistance to cuts is also necessary.
(TRA Codes E-2, E-3 and E-4)
Scraper tires, of which the wide base type is the most common, should have the same properties as those for dump trucks. Superior flotation and traction are also occasionally required.
(TRA Codes L-2, L-3, L-4, L-5, L-4S and L-5S)
Since front-end loaders operate on rough ground, cut and wear resistance are vital and the tires must provide stability for the loader body. Flotation and traction properties may also be necessary, depending on the working conditions. In certain cases, such as the wet and rough conditions of underground mines, the L-4S and L-5S with smooth treads are used because of their high wear and cut resistant properties.
(TRA Codes L-2, L-3, L-4 and L-5)
Since a tire dozer is used not only for dozing and leveling, but sometimes for pushing a motorscraper, tires with better traction than loader tires are necessary. Other requirements vary widely depending on job conditions.
(TRA Codes G-2 and G-3)
The motor grader, which is used for road leveling, clearing and snow removal, needs tires that provide high traction and directional stability. Other characteristics depend on job requirements.
(TRA Code C1)
Tire rollers use wide tread tires that uniformly distribute weight because of their primary use in compacting road surfaces.
Straddle carriers are special vehicles that are mainly used at seaport areas to carry ocean-going freight containers. These tires require extra heavy-duty performance, and wear and heat resistance, because straddle carriers operate continuously and turn frequently.
Towing tractors are used to move large aircraft. Thus, these tires mainly require extra traction.
