Description

Precise handling on dry roads

Lower wear for increased mileage.

Enhanced driving characteristics on wet surfaces for greater safety.

  • High pattern rigidity ensures precise steering behaviour and greater driving stability, particularly when cornering.
  • Optimised pattern geometry with wide center grooves and extra gripping edges ensures better water dispersion, more grip and thereby more control when steering and braking in wet conditions.
  • Refined pattern rib structure delivers well-balanced pressure distribution over the contact area, less rolling friction and increased mileage.

    Nice upgrade

    Steering response improved straight away after fitting. Very pleased. Fuel consumption seems slightly better since the switch. Stable and precise in summer heat.

    Strong performer

    Fine for the price. Slightly more road noise than I hoped on coarse asphalt. Balanced and predictable.

    Great value for money

    Does exactly what a summer tyre should. Happy with the purchase. Grip in corners is reassuring and the steering feels a bit sharper than before.
