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 5 out of 5 by from Great tires! Great, Fast Service. I absolutely love these tires! Best on the market, and these guys had the best price. I have a FWD SUV and finding a tire that has the grip and tread to ensure a smooth, safe ride was key for me. (My current tires were not due to be replaced, but they were stock cheapies from the dealer and weren't doing the job. During these last heavy rains in the area, I can say for the first time I was actually scared driving with the old ones.) These Cooper CTS tires are WELL worth the money even if no deal in place if you can swing it and put Michellin and others to bed. Pep Boys in Oceanside gave no hassle. Ordered the tires online, made an appointment through the web, rolled in at scheduled time, went to go eat dinner, and came back about an hour and a half later and they were done and drive great. No sales pitch, no up sell. I hate that, and I was appreciative they didn't try it with me. What I ordered is what I got. Totally new feel to my truck, and I would recommend them.

Rated 5 out of 5 by from Great value No need to waste money on premium brands. Yes Michelin and others are good, but I've gotten equal mileage and comfort from Cooper for years. Last pair of michelins I had showed dry rot on sidewall and after 2 years. Why would I pay $60-100 more per tire to have dry rot?

Rated 5 out of 5 by from EXCELLENT PRODUCT These Cooper Discoverer CTS tires delivered everything as expected. The results were smoother and more quiet ride, better handling and traction. I am totally 100% satisfied with these tires and plan to purchase another set when the time comes.

Rated 4 out of 5 by from So far, So Good A set of 4 of these replaced the 4 year old OEM Michelins that had about 56000 miles on them. Verhicle is a 2010 Ford Edge. The tread looks to be a bit more aggressive for better water dispersion and hopefully a better traction in slippery surfaces. Initial impressions are favorable for the tire. They appear to be a little shorter than the OEM tires, but only visual difference, does not seem to have a significant affect on speedometer. They seem to be a bit "sharper" handling than the OEM tires as well. The ride also seems a bit more tight. We have less than a thousand or so miles on the tires now, and have a trip coming up. If there are any negatives, I will post an update or second review to this. Especially when the offered promotion was calculated in to the purchase price, these seem to be a very good replacement for the stock tires.

Rated 4 out of 5 by from Very pleased I am very satisfied with the ride and wet traction with these tires. I am not an aggressive driver but do have many years and miles under my belt. After driving on many different brands of tires, these rank right up there with the best feel for the road. I am about 1500 miles into them so it's too soon to rate longevity and there hasn't been any snow to rate traction in snow although I never had trouble in snow with even tires needing replacing as how you drive is as important as what you're driving on. I would certainly recommend these tires based on my limited experience with them. I can't rate them with 5 stars until the miles and the snow have accumulated.

Rated 5 out of 5 by from So far so good I am very pleased with the ride and handling. Tires are quiet and have excellent grip characteristics. Half hoping for snow to run them through their paces.

Rated 5 out of 5 by from New shoes for my ride I did a lot of research online for tires euro to buying them. I unfortuabtley have one of those vehicles that has "special" tires, so it was going to be expensive no matter what. Pepboys had the tire I wanted in stock and a decent price. I was able to make an appointment online and saved a couple extra bucks. Arrived a little early and they got me in pretty quickly. And I got the buy 3 get 1 free. Win win all around.

Rated 5 out of 5 by from Heavy duty tread My Veracruz has never handled better. Shortly after installation we got a snow storm. Normally I would have been apprehensive about going out but decided to try it. These tires were great. They went thru the snow like a tank.

Rated 5 out of 5 by from Far better than OE These Cooper Discoverer CTS are great. Got a call from my son and daughter-in-law stating that in the recent snow storm we got the traction and control in their Kia Sorrento was better than when it was brand new on the original tires it came with. My daughter -in- law said she never felt so safe with my 5 yr old grandson in the vehicle. That's all I needed to hear.

Rated 5 out of 5 by from Very quiet ride I had to replace all 4 tires on my 2011 Kia Sorento and after reading other reviews I decided on going with the Cooper Discoverer CTS. I originally went into our local Pepboys and got a price. But then went home to do some quick research and discovered there was a 20% off coupon code on the Pepboys website which I was able to use. So it was almost like getting one tire for free. Installation was quick and no issues there. Once I took my first drive I noticed a huge difference. The bumps were dampened a lot and there was virtually no tire noise. I then had to take a trip to Nashville two days later and I was amazed how quiet they are on the highway. I've only had them for a month and didn't have to drive through any bad weather yet so we'll see what happens during a heavy rain storm or when it starts to snow. But so far I'm very happy with them.

Rated 5 out of 5 by from Big fan of Cooper Tires I have always liked Cooper Tires. I have purchased them as replacements for Michelin, Pirelli, and now Kumho tires. And it has always been for less money. I have only had these tires for a few weeks, but I am perfectly satisfied so far, and expect the same long life and great performance I have had with all my other Cooper tires.
