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: 340
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 out of 5 by Summer Tire This is a SUMMER TIRE. This is not meant to be mounted on car that sees snow. Great tire otherwise. January 7, 2015
Rated 4 out of 5 by Great Service, great product...but Overall, was very pleased with the deal I got and the service I got from the people at Pep Boys. Due to weird circumstances the day I went to get my tires changed there was a power outage in the grave and they had to load my new tires in my car and take it to a sister location nearby. Because my trunk was full, they had to put the tires in my car. I didn't notice until the next day, but the trim on my passenger side dashboard above the glove compartment got pretty severely scratched, but because I drive away in the night I didn't notice. All in all, the people were fabulous, but it was a bit of a bummer that the inside of my car got a bit scuffed up. They did their best and I appreciate how courteous they were, I iust wish that didn't happen. January 6, 2015
Rated 5 out of 5 by Amazing Grip! I've had the g-Force Sport COMP-2's on my Mini R53 for just over a month now and the grip is unreal!!! April 21, 2014
Rated 4 out of 5 by G-Force Sport Comp-2 on Challenger RT Very good grip on curve roads dry or wet roads..looks very nice on the Challengers..they say it is noisy..I can hear it but not that car is already loud..overall I really like it..great job BFGoodrich April 9, 2014
Rated 4 out of 5 by Noisy Nice grippy tires in the dry or in the wet. Rather noisy tire and on some surfaces, the hum is rather noticeable. January 16, 2014
Rated 5 out of 5 by Excellent UHP Summer Tire These Tires are fantastic. These were the first set of directional summer tires I have ever owned, and they exceeded my expectations. I would have bought them again but the price has risen about 50% and they will not last! November 22, 2013
Rated 4 out of 5 by More noise then g-Force T/A KDWS I bought these to replace my OEM original g-Force T/A KDWS on my 2007 Mustang GT Convertible, as I live in Florida and really only need a summer tire not all-weather. So far these tires are great for the price, but they definitely have a little more roise noise compared to the KDWS. I drive with the top down 90% of the time so perhaps I am more sensitive to it, but so far I can't really tell a big different between the COMP-2 and the KDWS except that the COMP-2 were less expensive and little more noisy. Grip seems about the same. I don't drive on the track, mostly surface roads and a little highway here and there. If a tiny bit extra noise will bother you, stick with the KDWS. September 17, 2013
Rated 5 out of 5 by gforce sport comp2 I got the outstanding performance on wet roads that I was hoping for. September 8, 2013
