With one side of its tread designed for winter and the other side for summer, the Vredestein Quatrac 5 is an all season tyre designed for compact and high performance cars.
Handling. The outer part of the asymmetric tread provides lateral grip and steering precision. The outer longitudinal groove designed to increase the tyre’s stiffness provides greater stability and enhanced handling.
Winter. Sipes on the inner tread blocks ensure excellent grip on snowy surfaces. “The 3D Grip Claws” technology, claws arranged between the sipes of the centre rib, ensures good handling in bends.
Economy. The full silica compound ensures a longer tyre life. The even distribution of pressures reduces irregular wear. Fuel savings thanks to a low rolling resistance.

Methodology for performance measurements
Sources refer to a market player who carries out independent tyre comparison tests, based on a stable methodology and broad performance criteria, to provide objective results for a range of similar tyres according to the type of use.
Only the sources that respect the criteria are included in the base. These criteria are also applied for every test source.
The sources used to establish the performances for a tyre are:
- Data from published tests from specialized media.
- Data from Regulation (EC) 1222/2009 "on the labelling of tyres with respect to fuel efficiency and other essential parameters". Or the most widely observed label values (MOBS) in the absence of official values*.
- Data published by independent test institutes.
Detailed list of the sources (not including Regulation (EC) 1222/2009) used to rate each product accompanies the display.
The structure of the ratings
The final rating is divided into 9 elementary performances, and an additional 4 elementary performances for winter tyres.
The elementary performances are grouped into 5 performance categories; 3 for summer tyres, and 2 for winter tyres.
Every elementary performance is integrated into its group with a different weighting according to its importance.
The performance groups and the elementary performances are as follows:
|General performances||Winter performances|
The methodology for the calculation
Every elementary performance is rated accordingly to the following princip:
- A score of 10 is given to a tyre which achieves the best result for a given test.
- The score given to other tyres decreases in proportion to the standard deviation of the selected discriminating factor.
- All results that are 9 times higher than this standard deviation obtain the score of 1.
If the source uses his own rating (when it is not on a base of 10), a linear transcoding is performed
The final score for the basic performance is the arithmetic average of the scores obtained for each test.
Note: Tests conducted by car magazines or specialised bodies generally cover the most common tyre dimensions available on the market. Even if performances vary slightly depending on dimensions, we have chosen to apply the rating to all dimensions for a tyre model.
The star rating system
The stars gives a graphic overview of the value for a performance group. They are given according to the following scale:
