The Blizzak WS80 is a new studless winter tire developed by Bridgestone for coupes, sedans, compacts and minivans. Rather than using metal studs as traditional snow tires do, the Blizzak WS80 utilizes modern advances in engineering to provide comparable results to studded tires. These tires have a hydrophilic coating, which reacts to water molecules to help you stop your vehicle in wet conditions. The tires are also made of Bridgestone's Multicell Compount with Nano Pro-Tech, which keeps the rubber flexible in cold weather. Regular tires become more rigid in cold weather, giving you less traction, and therefore less control, on the road.
Additionally, the Blizzak WS80's tread pattern and cavity shapes allow an even distribution across the entire tire, so the wear and tear is spread out rather than concentrated in one area that becomes a bigger problem. This design element helps the tire maintain more contact on the road, giving you more control over your car in icy and snowy conditions.
The tires include 3D zigzag sipes, or small cuts along the top of the tire that help it grip the road in wet weather. Bridgestone also increased the block edges by 20 percent from the WS80's predecessor, which gives your vehicle better handling in deep snow and slush. The tread is designed to channel water and snow out of and away from the tire, which is another design element that helps you retain control of your vehicle in rough driving conditions.
If your Blizzak WS80 snow tires become unusable for any reason, the tire manufacturer lets you replace them with an equivalent tire for a pro-rated price. Bridgestone honors this up to five years from the date of your purchase, so long as you have proof of purchase. If you don't have this information, you get six years from the manufacturer date. However, tires that are worn down to 2/32 inch or to the top of the built-in indicators are ineligible for this replacement option.
