340-80r18 tires

(550) Multipurpose

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.

This product is not covered by a manufacturer’s treadlife warranty.

Mileage Warranty

The maximum carrying capacity for a tire determined by the manufacturer.

Load Index

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

Max Speed

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

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

Part Number

Tread design (or tread pattern) can affect handling, traction & noise for different driving styles & road conditions.

Tread Design

Tire Weight

The diameter of a tire that is inflated without any load applied.

Overall Diameter

A three-peak mountain snowflake (3PMSF) symbol branded on a tire's sidewall indicates the tire meets required performance criteria in snow testing to be considered severe snow service-rated.

Three-Peak Mountain Snowflake (3PMS)

(585) IND SB R-4

Built for use on industrial applications such as skid steer loaders, forklifts, mining equipment, and so on. Industrial tires are strong enough to carry their vehicle's weight, and tough enough to withstand heavy usage and damage from off-road debris.

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.

Tread Depth

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

The measurement of width from a tires inner sidewall to the outer sidewall.

Multi Use 550

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.
