What's this? Overall score emphasizes snow or ice performance followed by safety-related tests, including braking, handling, and resistance to hydroplaning. Scores and ratings are held to a comparative standard within a tire category. For instance, winter tires in this report are not comparable to other charts or to previously tested tires.

Summary:The tire can be studded for enhanced grip on icy surfaces. Comes in numerous sizes to fit new and older cars on the road.
The General Altimax Arctic is part of the tire
test program at Consumer Reports. In our lab tests, winter/snow tire
models like the Altimax Arctic are rated on multiple criteria, such as those listed below.
Snow traction reflects the distance our test car needed to accelerate from 5 to 20 mph on moderately packed snow.
We tested ice braking on a skating rink from 10 to 0 mph.
Dry braking is from 60 to 0 mph.

Speed rating Speed rating. This letter denotes the maximum sustainable speed and is found directly after the load index. For S-speed-rated tires, it's 112 mph; for T, 118 mph. Speed ratings for other tires include Q, 99 mph; H, 130 mph; V, 149 mph; and Z, 150 mph plus. While such speeds may seem wildly impractical, tires with higher speed ratings tend to provide better handling at legal speed limits. Except for winter tires, choose tires that have a speed rating at least as high as the one specified on your vehicle's placard and consult the owner's manual. Speed rating may vary by size.
Tread The tread is what makes contact with the road. Patterns vary to suit specific performance criteria including tread life, handling, traction, and noise. Tread patterns incorporate ribs and tread "blocks" that contact the road and "valleys" between ribs or tread blocks called grooves for evacuating water. Slits in the ribs or tread blocks are called sipes that provide biting edges useful in wintry weather. Metal studs can be installed in studdable models for added grip on lice.
