Cooper Zeon RS3-A

The RS3-A is the latest ultra high performance all-season tire within the Cooper performance family. This all-season performance tire provides the driver with a dynamic handling tire that inspires confidence and control in all seasons.
  • An asymmetrical all-season ultra high performance w-rated tire featuring world class traction, exceptional handling and crisp steering response.
  • Silica formulated tread compound designed to provide driving performance that inspires confidence and control in all seasons.
  • Asymmetric tread design allows for tread pattern tuning allowing cross rotation which reduces heal-toe-wear
  • The inboard tread pattern is optimized for wet and light snow conditions. Two, wide circumferential grooves channel water away from the tire for hydroplane resistance
  • The silica formulated tread compound is designed for exceptional driving performance that inspires confidence and control in all seasons and weather conditions
  • This ultra high performance tire is constructed with three dimensional micro gauge siping which improves handling and tire control while reducing the possibility of stone retention. This type of siping also provides maximum wet and light snow traction

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: 500
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 & Excellent 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 Great tire Great tires! My car was loud, and I was about to trade it in. I felt like it had so many problems, but was unsure if it was just the tires. The tires were on the deal buy 3 get one free deal, so I went for it. It was the best idea!!!!! My car is like a whole new car. It's quite, and rides so much smoother. It's amazing what a good set of tires wil do. I booked my appointment online for a Saturday morning. When I arrived, I was told they could not find my tires. I went back home and waited for them to find them. After calling back and forth throughout the day, the manager went and picked them up at another store. I was very thankful for their great customer service!!! October 14, 2016
Rated 4 out of 5 by 40,000 Miles Exactly I got exactly 40,000 miles out of these, driving about 70% highway, 30% city. There was substantially more wear on the drive tires (front-wheel drive car), but rotation took care of this. Good tire, quiet at first, but got noisier as time went by. Grip was good, cornering was good. Overall good tire, but not great. Still a decent value. September 28, 2016
Rated 5 out of 5 by See below I have since put 2K miles on set of tires GA to Mo and rtn - no slip during downpours at 50+ and handles great on secondary and interstate roads. No more noise with these than the original Michelins at +95F. 2012 Fusion August 12, 2016
Rated 5 out of 5 by Excellent tire I put these tires on a Buick Lucerne. Coming from the Yokohama Avid S tires that were on there previously, it's like night and day. These tires are head and shoulders better than the Yokohamas. They are quite and trippy. I don't know how they will work in the snow, but I'm sure they will at least equal or be better than the Yokohamas. Overall I'm impressed with this purchase. June 12, 2016
Rated 5 out of 5 by Love this tires! I love my Mazda 3 but I always have had a hard time finding the right tire...until now. Copper is inexpensive and the all season tire feels smooth and just right for my car. Also, I got the buy 4 Pay 3 offer, so It couldn't be better!! I highly recommend this product Made in the US May 2, 2016
Rated 5 out of 5 by Great Tires,Great Deal Purchased a set of 4 RS3-A during the buy 3 get 1 free sale. The salesman at the Lombard store, Kevin, was fantastic in helping me select the best tires and deal for my Impala LTZ. Replaced OEM Goodyear RSA with these Cooper's, 235/50/18. and I must say my 36000 mile car is now handling better than ever. Love the ride and the traction is awesome. Feels better than when it was new. The tire were installed in an hour and the price came in lower than quoted, with a factory rebate of $60. Only been a few weeks but I must say I love them. Never felt better about a tire purchase. Thanks Kevin & PEP Boys !! April 11, 2016
Rated 5 out of 5 by Long warranty, great performace I was pleasantly surprised to get the full warranty life out of the tire, considering it was double that of my next choice, which was also a more expensive tire. I just bought a new set in December. Of course dry and wet/slush performance is excellent. Snow performance is very good, often surprisingly so. Noise has been minimal. February 4, 2016
Rated 5 out of 5 by Love these tires! I had these tires installed on my 2013 Hyundai Sonata after much research. The very next day I had to go on a 2,700 mile round trip to Arkansas. The car handled wonderfully. The ride was smooth, cornering was unbelievable, they handled very well in 4 days of rain and no tire noise! Tire noise is always one of my deciding factors. These tires are quiet! I just don't think you can go wrong with these tires. I'm very happy with the purchase of these Cooper tires! November 4, 2015
