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.

Passenger tires are some of the most common tires you'll find on the roads today, and frequently used on coupes, sedans, hatchbacks, minivans, and other passenger vehicles. Passenger tires are available in a wide variety of types, such as all-season, winter, and ultra-high-performance.

        manufacturer extended to the purchaser. We will be happy to assist in obtaining fulfillment of a manufacturer’s 
        warranty. Other than applicable manufacturers’ warranties, there are no warranties, express or implied, 
        including any warranty of merchantability or fitness for a particular purpose. The only tires SimpleTire can 
        warranty are brand new defects (meaning that they have not been mounted or driven on). Any bead damaged will be 
        void of any warranty claim. Any other adjustments should be taken to the nearest authorized dealer for that 
        manufacturer. Sometimes the manufacturer also provides a treadlife warranty and mileage rating. Please be aware

        manufacturer, may or may not come with a 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

Standards that measure treadwear, temperature resistance and traction, example: "640 A A".  The 640 is the treadwear test and it lasted 6.4 times longer than the comparison tire tested against.  The first "A" is the traction rating using straight-line wet traction on test surfaces (see information tables tab) and the second "A" is the temperature rating by testing operation at high speeds without heat-related failure (see information tables tab).

UTQG

Wet Traction is a piece of the UTQG for example if  UTQG is: 500 AA A, the wet traction piece is the second piece, the "AA".

Wet Traction

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

Tire Weight

The range of widths the rim of the vehicle can be for this tire to be safely mounted on.

Rim Range
