The Assurance WeatherReady is Goodyear's Grand Touring All-Season tire designed for the drivers of family sedans, coupes, crossovers, SUVs and minivans who want the smooth and quiet ride of a premium touring tire combined with the all-season confidence that comes from driving a vehicle equipped with tires bearing the Severe Snow Service certification symbol.

The special soy-based rubber tread compound of the Assurance WeatherReady is molded into an asymmetric tread design focused on providing the traction needed for any weather condition. Goodyear's Weather Reactive Technology delivers control in inclement weather with 3D TredLock Technology Blades in the center and outboard tread ribs to provide stable cornering in slippery conditions. Evolving Traction Grooves help retain high levels of grip as the tire wears. Added silica in the tread compound aids traction on wet roads, while the Sweeping Tread Grooves move water away from the footprint to the four deep, circumferential channels to resist hydroplaning. The intermediate ribs of the Assurance WeatherReady feature Zigzag Biting Edges to provide the traction needed for confidence in slippery conditions, including on ice and in snow. All Assurance WeatherReady tires meet industry Severe Snow Service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol.

Internal construction of the Assurance WeatherReady utilizes a single-ply polyester casing. Two wide, steel belts support the tread area, and a polyamide reinforcement aids handling response and high-speed capability.

Note: While non-winter tires featuring the three-peak mountain snowflake (3PMSF) symbol provide additional longitudinal snow traction beyond what all-season (M+S) tires not bearing the symbol can deliver, they do not match the capability of a true winter tire in all adverse weather conditions.

The Discoverer AT34S is Cooper's On-/Off-Road All-Terrain tire designed for the drivers of pickup trucks, crossovers and full-size SUVs looking for a tire that blends the off-road grip they need with the on-road comfort they demand. Engineered to deliver traction on any surface it may encounter, the Discoverer AT34S combines on-road manners with off-road capability and provides confident light snow traction that meets the tire industry's severe snow service rating requirements and earns the three-peak mountain snowflake (3PMSF) symbol.

Utilizing Adaptive-Traction Technology, the Discoverer AT34S combines a silica-based tread compound into the Secure-Grip all-terrain pattern. The open, five-rib design is engineered to provide wet and dry performance, in addition to off-road capability. The circumferential, Aqua Vac Channels and wide, lateral notches help evacuate water from the contact patch and resist hydroplaning. Micro-Gauge ZigZag sipes create biting edges for added traction in slippery conditions while retaining tread block stability for dry traction and handling. Snow Groove Technology utilizes saw-tooth block edges in the outboard grooves to retain snow in the tread pattern for snow-on-snow traction.

The internal construction of the Discoverer AT34Sconsists of a durable, two-ply polyester casing. A single-ply, nylon reinforcement above two high-strength steel belts further increases durability and handling response, along with providing high-speed stability.

Note: While non-winter tires featuring the three-peak mountain snowflake (3PMSF) symbol provide additional longitudinal snow traction beyond what all-season (M+S) tires not bearing the symbol can deliver, they do not match the capability of a true winter tire in all adverse weather conditions.

Tires Scores Compare

Would You Recommend?

N/A

Treadwear Performance

N/A
N/A

Treadwear is vital to many things, not just how often the tires need replacement. Hydroplaning and wet weather are both critical factors that wear down your tire quickly. The warranty covers any defects in what you bought but only for a limited period or when there's minimal tread left on them.

Wet Perfomance

9.3
9.2

The wet performance score is a new thing that tire manufacturers are trying to achieve. The hydroplaning resistance, wet traction, and steering response all influence this new grading system.

Hydroplaning Resistance
i

The hydroplaning resistance is measured by the hydroplane depth test and the dynamic aquaplaning test, which measures how much water can be accumulated on the tire's surface before hydroplaning occurs.

9.3
9.2
Wet Traction
i

Wet traction estimates the level of grip on wet pavement. Tread design with deep grooves dramatically improves confidence when driving in the rain as they channel the water out much better.

9.2
9.1
Steering Response
i

The vehicle's steering response largely depends on the tread depth, tire width, air pressure, and aspect ratio. Wide high-performance tires are equipped with a continuous center rib providing instant steering response.

9.2
9

Dry Perfomance

9.2
9.1

Tires with good dry performance should be able to perform smoothly and safely, even when cornering aggressively.

Cornering Stability
i

A dynamic cornering test is often used to assess cornering stability under dry conditions.

9.2
9.1
Dry Traction
i

Dry traction level depends on many factors, including tread design, profile shape, and compounds.

9.2

Steering Response

The vehicle's steering response largely depends on the tread depth, tire width, air pressure, and aspect ratio. Wide high-performance tires are equipped with a continuous center rib providing instant steering response.

Comfort Perfomance

8.9
9.2

The comfort performance score is designed to measure the balance between ride quality and noise level.

Ride Quality
i

The excellent ride quality means you do not feel the bumps or cracks on the road. Larger tires with thick and deep tread patterns decrease the number of jolts allowing you to glide over bumpy road textures.

8.9
9.2
Noise
i

If you would enjoy a quiet chat with the passengers while children are sleeping or listening to music, not the sound of tires, definitely pay attention to the noise score.

8.9
9.2

Winter Performance

8.8
8.5

Winter Performance score helps us understand if the tire is the appropriate option for winter conditions that your vehicle will face. Dedicated winter tires provide a firm grip when driving through snow and on ice. Performance winter tires boast a higher speed rating and better handling but deliver modestly lower ice and snow traction.

Light Snow Traction
i

Snow traction is the ability of a tire to push snow out of its path. When driving on packed snow, tires with good snow traction will help you accelerate and maintain control.

9.3
8.9
Deep Snow Traction
i

Deep Snow Traction test results compare how the tires deal with the deep snow. To successfully cope with the job, such tires should feature aggressive tread patterns, a tremendous amount of siping, and most elastic compounds.

8.7

Ice Traction

Ice traction tires feature ice grip and build friction when using the brakes or steering wheel to get through icy surfaces safely.

Size
i

Tire size may be indicated in two formats:
– metric (P255/45R18 103H)
– high flotation (30x9.5 R15 104 F C)
In the metric system, P - stands for the passenger vehicles (LT - for Light Trucks, ST - Special Trailer) with a width of 255 millimeters, aspect ratio (sidewall height) equal to 45% of the tire height. R means it is radially constructed with a diameter of 18 inches. 103 denotes the tire's load index and H determines the speed rating.
In the high flotation system, the first number (30) is the overall diameter of the tire, the second number (9.5) is the width in inches.

Max. load
i

The maximum weight that a tire can carry is the greatest amount of weight it's designed to bear. Because load carrying capability is dependent on a tire's size and construction, as well as how much air pressure is actually utilized, maximum loads are measured with the tire inflated to an industry standard inflation pressure.
