  Winter tyres - why do studless tyres not skid?

Studdless tyres ensure a firm grip by ejecting the film of water between the road surface and the tyres that causes skidding on snowy or icy roads.
Furthermore, the special compound rubber does not become hard, thereby maintaining the grip.


Characteristics of Bridgestone's studless tyres:
Made a foamed rubber with innumerable micro bubbles and channels that eliminate the water.
Air bubbles appear on the surface even when the tyre is worn to maintain the grip.

The tiny air bubbles keep the tyre fleixible, and supple for two or three winters, preventing loss of grip on ice roads.
Note: always use four studless tyres.
Mixing studless and regular tyres will cause the vehicle to spin when you turn or brake because of the different cornering power.

  Is there a tyre you can drive with even after a puncture?

With run-flat tyres, you can drive a certain distance at a specific speed.
You can drive safely even after a puncture.
You don't have to change to a spare tyre.
Not having a spare tyre saves resources, as spare tyres are often discarded without being used.
Without a spare tyre, vehicles weight is reduced, saving fuel and energy.

  Why are tyres black?
