12.5-80-18 tires

Contractor II

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.

Mileage Warranty

Maximum speed capability to safely carry a load for an extended period of time.

Max Speed

The maximum load carrying strength at the specified inflation pressure, also known as ply rating.

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.

Sidewall

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.
