Designed for use on tractors, sprayers, harvesters, trailers, implement control, and other farm equipment. These tires are typically designed to reduce soil compaction, resist damage, and provide high flotation so that drivers don't sink in soft surfaces.

Load Index

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

Max Speed

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.

Inflation Pressure

An identifier of a particular tire line and size combination assigned by the tire manufacturer.
