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 & 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.
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.


Definity Dakota A/T2 is rated 4.7 out of 5 by 43.
Rated 5 out of 5 by from great tire both on and off road I am running these tires on my o3 jeep wrangler. I run the 33x12.5x15 on a 10" wide rim. I have participated in many off road events running these tires which I air down to 12psi . I have been able to do all that the guys running swampers and such could do and still have a great highway ride. Tire wear is great, as by gauging the way these are wearing i expect to get 50k or more out of them... Good tire at a good price

Rated 5 out of 5 by from Great all around tire for the money! I have bought about 5 sets of these tries for my trucks. I am now getting ready to put another set on my truck. I have an 06 GMC 2500 diesel. I have a hunting camp in Kentucky and in Mississippi. I go back and forth to Kentucky 4 times a year. I have had no problems with these tires off road in the hills of Kentucky or Mississippi. I have also used them in the snow in the mountains of North Carolina with no issues. I keep my tries well maintained and rotated, for this reason I guess I have never had a flat nor blow out with these tires. If you have a truck I would recommend that you try these out if you do any light off road or hunting. I do recommend like the other person said that you get the LT version of these tires. The stronger sidewall makes a difference. Yea they may ride a little harder but when you need them for towing or off road you will forget all about the harder ride. And getting 4 for the price of 3 isn't a bad deal either! Drive safe and have fun, May the force be with! Yada! By the way anybody seen a Star-fighter with a Durmax in it? I'm missing one!

Rated 5 out of 5 by from Good buy! I've been running a set of these on my 2001 Dodge Ram for the past 4 years, and I'm about to purchase my second set. They've been great! I've paid a lot more money for less tire before. They are surprisingly quiet, which I did not expect when I first bought them. They have excellent traction in dirt, mud, and snow, and they seem to hold up really well. My only caution is to make sure you buy the LT rated tire - not the passenger version (which I don't understand why they even bother to make a 'P' version for a truck tire...(??)). A friend of mine purchased a set on my recommendation for his Ford Explorer, and he got the 'P' rated tires without thinking about it. His only complaint is that the tires are soft in the corners when going thru curves at speed. I don't have that problem with my LT rated tires, and we both agreed the stiffer side walls probably make the difference. Other than that - he's happy with them as well.

Rated 5 out of 5 by from Love these tires!! I'm fixing to buy my third set of these tires. I have 60,000 miles on the ones I'm getting ready to replace. These tires make NO noise going down the road, yet they have a pretty agressive tread pattern. I have never had any problem getting traction on any surface that I have been driving on. I've had these in mud, snow, ice and rain.
