Petlas Glacier W661. FEATURES AND BENEFITS: Enhanced controllability; Winter weather traction; Shorter braking distance; Improved durability; . OVERVIEW: The Petlas Glacier W661 is a touring, winter tire manufactured for passenger vehicles and SUVs.The model guarantees great winter performance. The special tread design and the winter compound improve wet, snow, and icy road grip. The ideal tread design keeps consistent road contact, while the winter compound boosts rubber flexibility in harsh winter conditions. The wide grooves and the siping detail resist hydroplaning, by eliminating water and slush from below the footprint. The tread design and the winter compound offer a safe driving experience in cold winter conditions.The tire guarantees great controllability. The tread design, siping detail, and wide grooves offer excellent road contact, upgrading handling and cornering. The tread design and the consistent road contact boost steering responsiveness and driving stability. The steering response is faster and more precise to the driver's commands, while the structure is secured against driving pressure. The wide shoulder blocks improve cornering and maneuvering and make the tire easy to control. This combination offers the driver full control over the vehicle, even on slippery and snow-covered road surfaces.The special tread design and the consistent road contact ensure a quick and safe braking ability. The tread pattern creates friction at the moment of braking, which shortens the braking distance significantly. The tread elements and the consistent contact guarantee that the tire is easy to control. This remarkable braking in winter weather makes it safer to perform even in harsh winter conditions.The Petlas Glacier W661 guarantees excellent durability. The stronger internal structure and the durable compound keep the ideal tire shape under driving pressure. As the tire does not deform under pressure, it is able to securely perform in cold weather conditions. This durable structure makes the tire safe to perform in winter weather conditions.Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
