YOKOHAMA off-the-road tires are also classified by type of vehicle and application suitable for usage.

 

TIRES BY TYPE OF VEHICLE

Dump Trucks

(TRA Codes E-1, E-2, E-3, E-4 and E-7)

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. High resistance to cuts is sometimes also necessary.

 

Scrapers

(TRA Code E-2, E-3, E-4 and E-7)

Scraper tires, of which the wide base type is most common, should have the same properties as those for dump trucks. Superior flotation and traction are

also occasionally required.

Front-End Loaders

(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.

Tire Dozers

(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 motor scraper, tires with better traction than loader tires are

necessary. Other requirements vary widely depending on job conditions.

Tire Rollers

(TRA Codes C-1)

Tire rollers use wide tread tires that uniformly distribute weight because of their primary use in compacting road surfaces
