Vredestein Quatrac 5
New benchmark in four-season tyres: the Vredestein Quatrac 5
Advanced tread design:
The new Vredestein Quatrac 5 is characterised by the sleek, asymmetrical design of the tread - a sophisticated symbiosis of winter and summer tyres. The profile on the summer side, with reduced air ratio, ensures excellent handling, great steering precision and plenty of lateral grip on dry and wet road surfaces. The winter side, which deploys sophisticated sipe technology, ensures exceptional grip on cold or snowy surfaces. Another striking feature is the asymmetrical outer longitudinal groove, the edges of which are placed at different angles in the tyre tread. This further optimises the stiffness of the tyre, resulting in greater stability and enhanced handling on dry road surfaces.
3D Grip Claws Several new technologies make their debut in the Vredestein Quatrac 5, such as the 3D Grip Claws. Arranged between the sipes in the middle of the tyre, they ensure perfect grip on bends and make it possible to accelerate quickly, even on snowy and icy roads.
Full Silica Compound:
Another new aspect of the Vredestein Quatrac 5 is the Full Silica tread compound mix, which is characterised by a special polymer composition. This ensures a high degree of resistance to wear – making for a long lifespan – while the even distribution of pressure results in an even wear pattern.
Innovative tread design: with an asymmetrical outer longitudinal groove for greater stability and enhanced handling on dry surfaces.
3D Grip Claws: great grip when cornering, faster acceleration on snow and ice.
Clever and attractive design: with unique summer and winter sides: optimised performance in all conditions.
Green EU tyre label: low rolling resistance, short braking distances on wet surfaces, exceptionally quiet operation.
Innovative Full Silica Compound: durability and long lifespan.
The European Union, under CE 1222/2009, has mandated that all tyres manufactured after the date of July 1 2012 for cars and commercial vehicles include standard EU Tyre Labels classifying them by three performance characteristics:fuel efficiency classified from A to G,wet grip classified from A to G, and noise emission in decibels.
Categories of tyres unaffected by this regulation include: retreaded tyres, professional off-road tyres, racing/sports car tyres, as well as certain types of tyres designed to improve traction such as studded tyres, T-type temporary spare tyres, tyres for cars built before 1990, tyres with a maximum allowed speed of 80km/h, tyres for rims with a diameter less or equal to 254 mm or greater or equal to 635 mm.
This label is intended on one hand to promote economic and ecological efficiency in traffic, as well as increase road safety, and on the other hand to help consumers select appropriate tyres by ensuring a certain degree of product transparency.
Nevertheless, the label has been criticized for only showing a very limited number of characteristics. Professionals argue that tyres have many more features that are important and relevant to road safety, including but not limited to aquaplaning properties, driving stability, service life, product properties on wet and dry roads other than wet grip, properties on snow.
Tyre manufacturers suggest that the test results from various institutions and industry magazines should remain a very important source of information for the end consumer, because they focus on and rate a wide variety of tyre properties and features.
