Selecting the right tyres for the season is critical for your safety.
Here is some information that will help you choose tyres best suited to weather conditions.
You can use summer tyres all year round if your vehicle use, the trips you make, and the climate of your region allow you to do so. Your summer tyres should always be in excellent condition, because in case of rain or snow, performance will be poor and perhaps unacceptable if the tyre is worn. Note that summer tyres perform very well on dry roads and have excellent grip.
Winter tyres are recommended for the period beginning in early November and ending in late March. Wear on winter tyres depends on your vehicle use, the trips you make, and your region's climate. Your winter tyres should always be in excellent condition, because worn winter tyres will be ineffective on snow as well as on wet roads. In order to maintain maximal grip on snow, PNEUS-ONLINE recommends that you mount 4 winter tyres to increase your vehicle's grip during the winter months and that you change these tyres when tread depth falls below 0.13 inches. Finally, you should know that using winter tyres will noticeably affect how your vehicle responds and its roadholding on dry roads.
All season tyres are a good compromise if you use your vehicle in both winter and summer. These tyres work well on all types of roads but are not specialised for any particular conditions. Compared with summer tyres, on dry ground all-season tyres do not perform as well and lack roadholding ability. They have less grip than winter tyres on snow. Your all season tyres should always be in excellent condition so that they perform well in any situation.
The anti-flat tyres are called RunFlat for Pirelli, RFT for Bridgestone or PAX for Michelin. They are compulsory for vehicles, which are not equipped of spare wheel, and just have an anti-flat bomb. If you choose the wrong tyre type instead of a run-flat tyre, its rim may be damaged if you drive the vehicle and the tyre will have to be repaired at the incident place. Please, notice that driving with an anti-flat tyre allows you to reach the nearest fitting station at a reduced speed -e.g. 50 mph on 125 miles.
