From the moment when the thermometer drops below 7°C (44,6°F), a tire's performance is reduced. The purpose of winter tires is to give your vehicle the best possible grip in cold weather.
It is recommended to fit winter tires between November and March inclusive. This recommendation is even more important for motorist who are likely to be driving in geographical areas where winter climate conditions are harsh. It is extremely important to have winter tires in top condition, because worn winter tires are of no use on snowy or icy surfaces. PNEUS ONLINE advises you to fit four winter tires (also called snow tires), in order to maintain good road holding in winter time and recommends that you change your winter tires when they have only 3.5 mm (0.14 in) of tread depth remaining.
From the point where the temperature drops below 7°C (44,6°F), the tire no longer has the same properties and both tire and vehicle reactions are affected.
Because of its characteristically high number of grooves, the tire's adhesion is optimised and the braking distance at low temperatures is reduced.
Winter tires give better traction on snow and black ice, even to the heaviest vehicles (4x4s, commercial vehicles, etc.).
A statement from the authorities for road safety: A survey in 2005 shows that 38% of accidents in winter involve at least one vehicle with all-season tires. These vehicles are highly overrepresented in accidents, since it is estimated that before 2008, 90% of passenger vehicles ciculated with winter tires. The proportion of loss of control is higher when more vehicles involved are mounted with all-season tires.
Tires specifically designed for winter driving constitute a safe solution for winter travel. They are designed for maximum traction on snowy or icy surfaces.
The purpose of chains is to penetrate deep into the snow layer and prevent it from accumulating on the tire which would result in it no longer being able to propel the vehicle.
Equipping your car with winter tires can avoid having to fit chains in 99% of cases.
They may only be used on snowy roads, whatever the season, and on sections of road equipped with B26 "special equipment compulsory"signs.
The manufacture of snow chains has been subject to special standards since 31 March 1986. However, the use of equipment acquired before this date is permitted.
Its use is not regulated. On the other hand, on sections with B26 signs, if "snow tires permitted"is not stated, drivers must use chains.
It is essential:
There is an alternative to the classic steel chain: the textile chain, recommended as ideal for narrow wheel arches.
