18x9.50-8 tires

Turf Saver

Like  their name suggest, all season tires are designed to give drivers performance year-round. All-season tires often provide strong performance in dry and wet conditions, and suitable traction and grip in wintery weather.

Lawn & Garden tires are built for use on riding or commercial mowers and offer drivers strong traction without the risk of compacting grass or turf.

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 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.

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

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

Section Width

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

Overall Diameter

Grassmaster

Knobby

Built for use on off-road terrains such as dirt, sand, gravel, and mud while also providing some on-road performance. ATV/UTV tires are commonly tough enough to handle any terrain and feature a high flotation design to prevent sinking.
