Technical information
Focus: Standard
The largest and best-selling category, and Cooper DISCOVERER WINTER belongs to it. No single property is pushed here at the expense of the others — comfort, grip, noise and tread life keep a sensible balance. For most drivers it is the safest bet: the tyre behaves predictably in the dry and in the wet and covers a decent number of kilometres.

What owners say
Compared to the all season Pirelli Scorpion and Michelin Pilot Sports I have used before I am amazed by how well these winter tyres perform. In the dry they are a
fraction less precise and grippy but only by a very small margin. Rolling comfort is a little better on the Coopers as compensation. In the wet, particularly as the
temperature drops they are vastly superior to the all season tyres with really clingy grip even on greasy surfaces with super progressive breakaway. You really can take liberties. On fresh light snow they grip well and on icy roads they retain control where normal tyres would just let go. I have not driven them on snow deeper than about 5 inches. Naturally being a low temperature tyre they wear quickly if driven at high speed in summer relative to an all-season. I fit them during the winter and use the all-seasons in summer so I get the best of both worlds. Highly recommended for winter safety and security!
