Davanti DX740 – 225/60R17 (99H) Davanti’s DX740 tyre is specifically designed for SUV drivers with an optimum balance of wet, dry and muddy grip, offering a smooth, comfortable drive in any conditions, on any surface.Four longitudinal deep grooves run the circumference of the tyre to provide drainage from the road contact areas of the tread pattern. The inner block section works in conjunction with the outer-inside block section to dissipate water out of the central grooves and away from the contact zone.
