Speed Rating
Load Index
Load Range


Safety Rating is a combination of two values: Load Index and Speed Rating for P-Metric and Euro Metric tire sizes; and Load Range and Speed Rating in the case of heavy duty LT (light truck) sizes.

Speed Rating is based on the speed that the tire is designed to be driven at for extended periods of time. All tires in the in the U.S. are designed to maintain legal U.S. speed limits. The speed rating of tires must match the maximum driving speed of the vehicle.

Load Index is used on P metric and Euro Metric sized tires and denotes a tire's load-carrying capacity at a specified inflation pressure. The load index is represented by a number, the higher the Load Index Value the greater the load the tire can safely carry. Vehicle manufacturers recommend a maximum load capacity based on a recommended minimum load index.

Tire Class


Tire Class reflects how the tire will be used. There are four major categories: All-Season, Max Performance, Summer-Only and Winter-Use.

All-Season tires are suitable for year-round driving in all weather conditions.

Summer-Only & Max Performance tires are specifically designed for high-performance driving. Tire compound, tread design and speed ratings all combine to hug the road and maintain grip. Summer tires by nature are not ideal for winter driving due to lack of siding to grip winter roads.

Winter-Use tires have tread compounds and patterns that are specially designed for grip on snowy or icy road surfaces. They are not suitable for year-round use. The rubber compound used will wear more quickly on dry, summer roads. It is recommended that winter tires are fitted as a complete set to avoid potential handling issues.

Tread Type


Tread Type is an important consideration when choosing a tire. There are four main types: Passenger, Highway, All-Terrain and Mud-Terrain.

Passenger denotes a tread that is suitable for normal use, a good all-round tread for normal driving.

Highway is a tread type unique to SUV and truck tires. The tread is optimized for normal everyday driving on paved surfaces. These tires can be driven off pavement, but are not ideally suited for off road traction. Highway tread patterns deliver a quiet ride.

For light trucks and specialty vehicles, All-Terrain tread types provide better off-road traction than standard highway truck tires. There more aggressive tread tends to be less quiet on paved roads. All Terrain tires are suitable for everyday use.

Mud-Terrain treads are specifically designed with wider tread blocks and higher void ratios to gain traction in off-road conditions. Mud Terrain tires can generate higher noise levels and tend to carry lower mileage warranties than other tread designs.

UTQG - Uniform Tire Quality Grade

UTQG (Uniform Tire Quality Grade) is made up of three values: treadwear, traction and temperature.

Treadwear is a relative numeric score, based on manufacturer tests, showing how well a tire can be expected to wear compared to other tires. A higher score means a tire could be expected to wear better.

Traction measures the tire's ability to stop a vehicle on wet roads. It doesn't reflect a tire's acceleration, cornering, or hydroplaning performance. Traction grades range from AA (highest) to C (lowest).

Temperature grades the tire's ability to withstand heat build-up, with A being the highest grade and C the lowest.

A - Over 115 mph
B - Between 100 to 115 mph
C - Between 85 to 100 mph
Treadwear: 700
Traction Asphalt - gForce
AA - Above 0.54
A - Above 0.47
B - Above 0.38
C - Less Than 0.38
A - Over 115 mph
B - Between 100 and 115 mph
C - Between 85 and 100 mph

Drive / Ride Performance Characteristics

All tires have the following six performance characteristics, divided into three sets of trade-offs. In most cases, a tire may perform excellently in one characteristic but only standard in the other.
Excellent Ride Comfort & Excellent Handling
Handling: Get stiff side wall for precise steering and cornering but settle for a firm ride with increased road noise.
Ride Comfort: Enjoy a quiet, smooth ride but lose some cornering ability.
Standard Treadwear & Excellent Traction
Traction: Stop faster in wet conditions but expect a shorter tread life.
Treadwear: Get long, uniform wear across your tread pattern but expect less traction in wet conditions.
Excellent LowRolling Resistance & Standard High Speed Performance
High-Speed Performance: Get increased performance at higher speeds but sacrifice some fuel economy.
Low Rolling Resistance: Enjoy improved fuel efficiency but expect less high-speed cornering ability.


Rated 4.7 out of 5 by 29 reviewers.
Rated 4 out of 5 by Good tires, bad service I put my first 1000 miles on these tires in a 2014 Toyota Venza. The Cooper Discoverer CTS are decent, competitively priced tires. Road noise and comfort are somewhat better them OEM Bridgestone. Handling is good. For the price, these are very decent tires. Now the bad part. Pep Boys on Montgomery Rd. Cincinnati. First the manager tried to convince me that these are studded winter tires and pushed more expensive tire options. Then, the tech that installed the tires forgot to put valve stem caps on two of the wheels. And they inflated two of the tires to 44 psi, one to 41 and one to 36 psi (Toyota spec is 32). Very bad and dishonest service. I give Pep Boys one star only because there is no zero star option. October 16, 2016
Rated 5 out of 5 by Good tires Quiet and comfortable ride September 6, 2016
Rated 5 out of 5 by Super quiet tires I am impress extremily impressed. My Mazda cx7 original tires were not as smooth and quiet as the Cooper Discoverer, since the first day I was smiling with the appearance and performance my vehicle run almost road-noiseless, this is something very hard to get at a unibody vehicle, happy so far, let see how they last thought the 60000 miles warranty.

Rated 4 out of 5 by SUV Buick Very good product and smooth ride for Suv May 13, 2015
Rated 5 out of 5 by Excellent Tires!! Very smooth and quiet ride on my 2011 LR2. These were my first set of Cooper Tires and I am very happy with them so far. They were very good in wet and snow conditions. I had a set of Continental Tires that came with the car and they lasted for 40,000 miles. The Cooper tires were much quieter and much smoother than the Continentals. This was my first tire purchase at Pep Boys and I am very satisfied with the service. The guys were great and I will definitely go back again! January 29, 2015
