Tyres: they are what touches the road!
Pay particular attention to the condition of your tyres. With the rain and the leaves falling from the trees, the ground cools down and becomes quite slippery from autumn onwards. As a result, fitting winter tyres, which provide optimal road holding in bad weather, can prove to be a very good choice for your safety.
These tyres, with a winter compound, are developed so as not to harden below 7°C; their siped structure gives much better grip on cold ground. So-called "4-season" tyres (Vivaldi or other brands) are an interesting alternative, especially in regions not directly affected by the "Mountain Law" (in force since 2021).
In mountain municipalities designated by prefectoral order, from 1 November to 31 March you must have either winter tyres (marked 3PMSF since 1 November 2024; M+S alone is no longer enough), or chains or snow socks in the boot. In these areas, it can be more effective to fit your car with snow tyres or winter tyres, which are even more effective, and to have another set of 4 wheels fitted with ordinary tyres, better suited to fine driving conditions. It's all a question of the weather more than the date!
