Developed for small and large passenger cars, the Yokohama BluEarth-4S AW21 all season tyre features the latest technologies to ensure reliability in all weather conditions.

Handling. Large blocks at the shoulders provide stability when cornering. The large area in contact with the road and sipes that increase tread stiffness ensure a high level of performance in dry conditions. In wet weather, water is quickly drained through V-shaped grooves and the centre rib to improve grip.

Winter performance. Crossing narrow grooves and sipes provide the biting edges required to keep moving along snow covered roads. The tyre is 3PMSF certified following tests on snow. The use of micro-silica in the tread compound keeps the tyre flexible at low temperatures and ensures optimum winter grip.

YOKOHAMA GOES ALL SEASON WITH THE BLUEARTH-4S AW21

Intended for urban drivers who occasionally have to deal with cold and snow, the BluEarth-4S AW21 is designed to deliver balanced performance no matter the season or weather conditions.

Winter technology for year-round performance

Although combining both summer and winter performance, the BluEarth-4S AW21 is notable for its use of Yokohama’s latest winter tyre technology. A combination of V-shaped and horizontal crossing grooves provide a good level of performance on wet, snowy and icy roads.

All this is backed up by a cold-resistant rubber compound made of silica and polymer, similar to that used in the Yokohama W.drive V905 winter tyre. In recognition of its winter capability the BluEarth 4S AW21 was awarded the 3PMSF Mark from the American Society for Testing and Materials (ASTM International) – one of the world’s largest standards organisations.

Moving on to summer performance, the BluEarth 4S AW21 boasts a new tread pattern, designed to maximize the surface contact area between the tyre and the road. This has the benefits of enhancing dry performance and extending tyre life.  Large, siped, shoulder blocks make this a wide tyre which, the manufacturer claims, delivers optimum performance on dry surfaces.

Availability

The BluEarth 4S AW21 is available in at least 30 sizes for 14-inch to 19-inch rim diameters.
