Welcome to our Crackley Garage information site about winter tyres.
From October to Easter, from O to O - this is a rule of thumb for the use of winter tyres. Even though it might be the busiest time of the year in our workshop, it is worth coming to see us and get winter tyres fitted alone for security reasons. A new set of winter tyres is always cheaper than accident damage on the vehicle.
Characteristics of winter tyres
Winter tyres are specially developed for low temperatures. Compared to summer tyres, they have a softer rubber compound, which still has sufficient elasticity even at low temperatures and does not harden. This flexibility of tread ensures better grounding and more safety in winter. To further increase the traction, winter tyres have more grooves in the profile than summer tyres and also numerous slats in the individual profile blocks. These provide a variety of grip edges, which can be even better interlaced with slippery surfaces. In wet conditions - as is often the case in winter - the wider profile grooves offer a further advantage: They drain water faster and thus minimise the risk of aquaplaning.
Profile depth and air pressure
There are also strict guidelines for the profile depth of winter tyres. By law, the minimum profile depth is 1.6 mm - but we, like many automobile clubs (RAV, AA etc.) recommends even 4 mm. Besides, car clubs recommend exchanging winter tyres at the latest after five to six years, since the initially soft rubber compound hardens over time and the traction is consequently diminished.
Also, the tyre pressure should always be in view, especially in the winter. At cold temperatures, the air pressure in the tyre increases less during driving than in summer. Therefore, winter tyres should be filled with about 0.2 to 0.3 bar more than recommended by the vehicle manufacturer. This also saves fuel. But please note, the advantages of winter tyres described above quickly become a disadvantage in the warmer months. Braking distance and fuel consumption increase at warmer temperatures, the tire wear is also much higher because of the soft rubber mixture.
How to choose winter tyres
To find the right winter tyres, you should have a good look at our website, look at different criteria and match them with one of the many brands we have to offer.
As far as the criteria for the selection of winter tyres are concerned, the tyres should be selected in addition to the correct size according to the requirements of the respective vehicle. This applies to both the speed index and the load index. You can find the correct tyre size for your vehicle in the vehicle registration form (V5). The new EU tyre label is also helpful when selecting new tyres. On it, you can find information on the fuel efficiency (rolling resistance), wet adhesion and the rolling noise of a tyre. For winter tyres, other criteria will soon follow, such as braking on ice or the grip on snow.
