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: 400
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 1 out of 5 by 235/50/18 g force kdws purchased a 2005 bonneville gxp from a large dealership who put these tires on for me and they have been trouble ever since, I have a harmonic imbalance in the tires starting at 67mph, and gets worse until 77mph, i've had the tires rebalanced twice and the oem rims check for trueness and rotated. there even worse when its cold. I've also have had all the suspension checked out and front end alignment. the car has only 90,000 miles on it and these tires have 4000 miles, they have been terrible since day one !!!,,, dealership dosen't offer tire warrantys on used vehicles so im stuck with these till there wore out. would'nt buy them again.

Rated 5 out of 5 by Bullitt owner These tires came as OE on my 2008 Mustang Bullitt. At 33,000 miles, they really didn't need to be replaced but I got a great deal on a new set and just switched them out. The new ones are much quieter and the grip is amazing. Very happy with them and especially with the lateral grip. November 28, 2012
Rated 2 out of 5 by tread cracks 255/50r17 owned this 1996 impala SS since Nov 1995. never had any issues with these tires except they wear out at 35,000mi. the tires are rotated every 6,ooomi. In 2007 I installed the 3rd set of tires. in 2010 the tread cracked on one tire between the inner and outer treads all along the rolling surface. tire was replaced warr adjustment. now sept 2012 2 tires have the same exact defect in the same exact tread area. for some reason the one tire purchased in 2007 has no cracking anywhere. the tires that had cracks only did so on the tread. Side walls etc look new , perfect looking , that to see tread cracks is quite a surprise . tires that now failed have 15,000mi . Vehicle has 70,000mi and is in perfet condition September 8, 2012
Rated 4 out of 5 by Marauder owner I am currently using my 7th set of these tires. They have given me excelllent service and last at least 30,000 miles each time. June 13, 2012
Rated 1 out of 5 by Garbage tires Several times a week. These tires dried out. The first one after five years and the rest including the newest at 19,000 miles. They decomposed and the left rear time got a hole right by the air filler. These were the worst tires ever purchased that came with the car. Now I'm buying replacement tires and you'll never see a sale from this family again. I'd appreciate some kind of monetary advantage in a check. April 10, 2012
Rated 5 out of 5 by Best Tires For An Everyday Driver I have a 2006 Mustang GT. These tires have great grip from new right down to the last bit of tread in dry and wet conditions. I live in Florida and I never have to worry in the rain. I've put about 60K on these and I'll need new ones in about 5k. I'm going to get another set of these. March 1, 2012
Rated 5 out of 5 by BEST TIRES IN 40 YEARS I am a super commuter driving a 2008 Ford Mustang approximately 150 miles per day round trip to work and back. As of this comment I have over 85,000 miles on this set of 235/50ZR18 97W g-Froce T/A KDWS tires that came with the car when bought new. I still have approximately 5,000 miles left in the set before they require replacement. Well done BF Goodrich! February 1, 2012
