Off the road tire (OTR)
Tires designed primarily for use on unpaved roads or where no roads exist, built for ruggedness and traction rather than for speed. OTR tires are tires that are designed and built for use on unpaved surfaces, installed on equipment such as wheel loaders, end dumps, scrapers, cranes, graders, haul trucks, and straddle carriers. Every major tire manufacturer builds tires that fit on pick-up trucks, dump trucks, or tractor-trailers that are designed to be used off the road at some time. Farm tires are used almost entirely off the road. However, these types of tires are not considered OTR tires.
Mining Tires aka: Earth Mover Tires are incorrectly classified as an OTR tire, however they should be consider as a separate category.
Considered to be among the largest tires in the world, an average mining tire is in excess of 12 to 14 feet in diameter and can weigh as much as 8 to 12 tons each.
The equipment and tires used in mining applications are subjected to severe conditions both above ground and underground. The mining surfaces are generally not well maintained and are laden with rock, sand, gravel, damp soil conditions and often oil contaminated water.
