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 load carrying strength at the specified inflation pressure, also known as ply rating.
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.
Shipping weight (lbs)
