Barum Quartaris

The primary factors in the development of the tyre were a safe grip on dry and wet road surfaces, as well as in slightly wintry conditions.
Therefore, the tread has been designed to combine elements of summer and winter tyres. To do this, Barum has developed a unidirectional tread, characterized by a special, innovative sipe system. The all-season tyre is particularly suitable for drivers who do relatively little annual mileage and who mainly drive around town.

All-season tyres are particularly popular among drivers who wish to run their cars cost-efficiently and who, therefore, wish to avoid having to switch from summer to winter tyres. Seeking to satisfy these demands, the Barum Quartaris has been developed as a compromise between the requirements placed on summer and winter tyres. A new feature of the Quartaris is the BASSS sipe system (Barum All Season Sipe System).

The Quartaris comes with the new winter tread-depth indicator to give drivers a clear idea of how suitable the tyre tread is for winter use. The tread grooves, characterized by a snowflake, are raised between the tread blocks.

The Quartaris not only provides for driving safety in winter, it also comes into its own on wet roads. This is made possible by the unidirectional tread with wide circumferential and lateral grooves which can take up and disperse water quickly. Flat sipes in the center and on the shoulder of the tyre act like windshield wipers which can displace water during braking. In addition, the silica mix creates for good adhesion and short braking distances on wet surfaces.

To facilitate safe driving in summer, Barum has designed the Quartaris with two straight bands running around the middle of the tread, as well as with large, stable shoulder blocks. The bands aid steering precision and short braking distances, while the shoulder blocks allow for precise handling on bends.
The Quartaris is characterized as an all-season tyre with the M+S marking, as well as with the snowflake symbol. Like any all-season tyre, it is a compromise, albeit to the highest possible standard. Therefore, Barum recommends this tyre in particular to drivers who mainly use their cars for trips around town.

Tread	Features & Benefits
	Safety in snow and ice! "BASSS" - Barum All Season Sipe System - causes a high number of edges to be formed which results in outstanding traction on snow and short braking distances on ice.
	Safety on wet roads! The efficient water dispersion through a directionally-oriented tread pattern with wide circumferential grooves and shallow sipes results in good aquaplaning characteristics and short braking distances.
	Safety on dry roads! A straight circumferential rib, as well as sturdy shoulder blocks provide support for the blocks and high block stiffness. The result is a precise steering response and a short breaking distance.
