- Tread pattern enhances traction and handling performance
- Able to handle higher loads at lower inflation pressure
Off-the-road (OTR) tires are built for vehicles like skid steer loaders, cranes, construction dump trucks, graders and other heavy-duty construction and industrial vehicles. OTR tires are incredibly tough and able to carry massive loads on soft or rough surfaces without sinking in.
This product is not covered by a manufacturer’s treadlife warranty.
The maximum carrying capacity for a tire determined by the manufacturer.
Maximum speed capability to safely carry a load for an extended period of time.
The side of the tire between the tread and rim, with cosmetic branding as well as information about the tire including manufacturer, model, size, etc.
Measured in 32nds of an inch, this metric shows how much tread life is left on a tire, with the tire's traction & stopping capabilities greatly diminished at 4/32nds and less. Tire manufacturers include "tire wear bars" at 2/32nds to indicate when your tire is worn out.
The highest inflation pressure (measured in pounds of force per square inch, PSI) the tire is designed to contain, and should only be used when called for by the vehicle placard.
An identifier of a particular tire line and size combination assigned by the tire manufacturer.
