Komatsu 31×10-20 Solid Tire

OTR tires stand for Off-The-Road tires. These tires are specifically constructed to withstand massive amounts of weight (like that of a heavy construction vehicle) while tackling harsh and uneven ground conditions. OTR tires are installed on skid steers and other wheeled heavy equipment.

There are plenty of OTR tire applications for operators of heavy construction equipment. Generally, OTR tires are used on construction equipment that will perform work on pavement, dirt, gravel, snow, or grass, and other harsh ground. OTR tires are great for construction work, excavation, mining sites, oil and gas projects, landscaping, roadwork, highway projects, and demolition work.

The easiest way to make sure your tires are the right size for your heavy equipment is to consult your manufacturer’s spec book, which will have standard tire sizes listed for your heavy equipment. There are countless different sizes, weights, and measurements required for OTR tires. In addition, you will need to measure the offset of the mounting surface (inset and outset, how much the wheel mounting surface differs from the center line). By consulting the manufacturer’s spec book, you can order the correct tire size without having to do any measurements yourself.

Generally, heavy equipment operators assume that OTR tires will last between 600 and 1,200 operating hours. However, there are numerous factors that will affect how long OTR tires will last. Low-cost pneumatic tires are inflated and more prone to pops and leaks. Solid skid steer tires will never pop, but they are much more expensive and the tread will eventually wear down. In addition, harsher ground conditions like sharp rocks will decrease the lifespan of OTR tires.
