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: 520
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.
Standard Ride Comfort & Standard 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 & Standard 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.
Standard Low Rolling 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 4.5 out of 5 by 46 reviewers.
Rated 4 out of 5 by Good Value This is the second set of these tires that I have owned. Really loved the first set.....until they passed 40K miles. Then, I had three tread separations in six weeks and had to scrap them for some used tires. I chose to purchase them again for another truck when I saw the mileage warranty had increased to 50K miles. Hopefully I won't have the tread separation problem when they get to 40K plus miles.

Rated 5 out of 5 by dekota definity a/t second set i have purchased. great all around tire. December 8, 2013
Rated 4 out of 5 by Too early to tell about product purchased Pep Boys Staff were great to work with and worked hard to have our car ready as promised. Will do business with this location atain November 25, 2013
Rated 4 out of 5 by So far, so good 4 stars for now. I want to see how they handle snow and some light off road conditions first. November 12, 2013
Rated 5 out of 5 by GREAT I have used the AT tires for years and I have to admit, you get your bank for this tire. November 9, 2013
Rated 1 out of 5 by All four tires wore out way before the warranty Kept up on tire rotation and proper inflation. Don't drive that many miles to work or traveling. All 4 tires wore down to baldness in a little over a year. Est amount of miles since purchase 15,000. Wont buy these again!!! October 29, 2013
Rated 5 out of 5 by Best value in an all-terrain tire First of all, the price was excellent. 10% off and buy 3 get 1 free. I am a tire nut and I am always researching them, even when I don't need new ones. The only tires I wanted more than these were BF Goodrich AT, but they were $320 more for a set of 4. These tires have a very similar tread (although not quite as aggressive). They are also similar to the General Grabber AT. They are made in USA by Cooper Tire. If you can find a cheaper tire, they are probably poor quality from China. They have a 50,000 mile warranty. They are smooth and quiet going down the road. They have lots of siping to grip the ice and snow. I don't have a single thing bad to say about them. The only thing that remains to be seen is how long they really last. I would recommend them to anyone. October 12, 2013
Rated 5 out of 5 by Great all around tire for my trucks. This is the third set I've bought. I have them on my Bronco, my Toyota Pickup, now my Dodge Van. Great all around tire as I spend 10% of my time on dirt roads and trails, towing dirtbikes. Tire is a fine all terrain tire. October 10, 2013
Rated 4 out of 5 by Great tire for Ford F-150 Love the profile of these tires! Surprising quiet ride and a good smooth ride for my old truck!! September 12, 2013
Rated 5 out of 5 by This tire more than meets my expectations. The tire tread design and OWL really make this tire standout among competing tires. Very pleased with the tire features and the price was right. September 9, 2013
Rated 5 out of 5 by These Tires Have Great Tread Pattern for 4X4s Purchased 4 of these about a month ago & so far all is good, gotta luv the tread pattern especially for SUVs & 4X4 vehicles.I chose blackwall out not white lettering for this SUV. August 29, 2013
Rated 5 out of 5 by New Tires I have two tires replaced but they didn't check the tire pressure so all four tires have a different pressure in them ranging from 32-48 August 27, 2013
Rated 5 out of 5 by Best Tires This is one of the best tires I have had, It has a very smooth ride. August 18, 2013
Rated 5 out of 5 by Great Tires Second time I purchased Definity tires August 9, 2013
Rated 5 out of 5 by Definity Dakota A/T My Escape drives 100% better with these tires. For as long as I own this vehicle, I will always put these tires on it. It made a world of difference!! August 5, 2013
Rated 4 out of 5 by nice tire Good tire, reasonable price, some noise when driving highway but expected, they run well in dry and wet weather. August 5, 2013
Rated 5 out of 5 by tires Handle very well in wet weather, low road noise. very happy with purchased. Extremely close to the BF Goodrich tires I have on other trucks. Installed onto 2001 Dodge Ramm 1500 July 31, 2013
Rated 5 out of 5 by Great product Very nice ride, Low noise and great handleing July 11, 2013
Rated 5 out of 5 by Good tires for my 4X4 pickup Tread caught my eye first, then the DAKOTA outlined label (I drive a Dodge Dakota), then that they are a Cooper Tires product. I expect the handling and dependability to be top-notch, and between Pep Boys and Cooper the warranty should be top-notch too. I already have Magnaflow noise, so if there is tread noise, I can't tell. I live on a hill, so when others are stuck or staying in, I should be good t' go! July 5, 2013
Rated 4 out of 5 by Seems like a very good tire The tires have done just fine so far June 19, 2013
Rated 3 out of 5 by good tire for price looks good if you want an inexpensive at tire look. traction not as good on wet surface as expected by other reviews. happy with tire for the price June 18, 2013
Rated 5 out of 5 by Treading Now These are nice tires with excellent traction, looks and performance.The price and warranty makes these tires irresistable June 6, 2013
Rated 5 out of 5 by Great tires for the price! Very happy with my purchase. The tires look amazing and I had a great experience with the Pepboys installation! May 22, 2013
Rated 5 out of 5 by Great tire for the money This set of tires is remarkably impressive for the price. So far no issues in rain or on dirt/gravel roads, and the ride is pretty smooth. As far as road noise, it sounds like a truck. The noise is not loud or obnoxious, and handling is very good. I would definitely recommend this tire to someone looking for a good All Terrain tire at a great price. April 11, 2013
Rated 5 out of 5 by Great all around tires Good traction,low road noise. Works great in the sand belt of north Caroline. March 21, 2013
Rated 4 out of 5 by Good affordable tire Looks exactly lile the BFG all terrain, but at a fraction of the cost March 16, 2013
Rated 5 out of 5 by Good value Good tires for the price. March 15, 2013
Rated 5 out of 5 by little road noise which i like the road noise so im very pleased with the tires March 15, 2013
Rated 5 out of 5 by nice and CHUNKY I really am glad to have purchased the tires. It seemed to make a big difference in the way my truck drives. Although it took about 3 hours for the tires to be put on..... I am glad I got them. Also my TPMS came back on to my dash along with flashing word LOW TIRE... So anyway. Thanks March 13, 2013
Rated 5 out of 5 by Highly recommend for quality and durability - Does lower MPG Put on my 2000 Jeep Cherokee (XJ) 2wd, 4cyl about 3 years ago. Only put about 20,000 miles on them but still have plenty of tread. No sign of dryrot. They've been great in all conditions (Dry, Rain, Snow, trail). I will say that I was getting 28-30mpg hwy with my stock street tires prior to this. Now I'm getting 21-23hwy. But they have taken some abuse that my street tires couldn't have taken. March 12, 2013
