The distributor of tyres Euromaster has invited us to take the wheel on the circuit of la Ferté Gaucher, to the east of the Seine-et-Marne, to judge the behaviour of the various types of tyres available on the market: “winter”, “summer” and “four seasons”. The models tested are all of the same brand, so that the test is truly representative.

today, the gum is the most common on the market is the tire “summer”, but the “four seasons”, despite being the least used and most expensive, does not cease to gain ground. The tires “winter” will be mandatory in the mountainous areas in the winter of 2019-2020, and he should know as the tire “four seasons” will also circulate in these areas.

We tested three types of tires: “winter”, “summer” and “four seasons”. Euromaster

Our test is not actually carried out in winter conditions, since our arrival, the track was dry and its temperature was 8°C. The winter tyre, really effective when the soil temperature drops below 7 degrees, is not to his advantage. For a more complete experience, the track was wet in places and included two workshops: avoidance and emergency braking.

The cars put at our disposal were of the Peugeot 308, the compact sedan the most popular of motorists in French. With the mounts “four seasons”, the car is not a model of accuracy at the time of entry in the curves. It feels like a bit of a wobble in the steering but without the effectiveness and safety not be disturbed. In addition, it is with this type of tyres that our braking distances were the shortest.

Equipped with tires “winter”, the 308 loses accuracy at the time of steer. In turns, it is hard to stay on the rope by increasing the pace because the car is going to inevitably under-steer. Let us not forget that the conditions were not conducive to the use of these tyres, which have not been able to reveal their full potential. On the other hand, loss of grip are never brutal with such gums, which provides a sense of comfort and security.

The grip without flaw, and the remarkable precision of tyre “was” in these conditions, make you want to draw trajectories in chalk. Things go wrong, however, on a stretch of road in the wet and cold, where the car is going to react brutally.

The ideal, in our view, remains to alternate between winter and summer tyres depending on the time of year. Thus the best possible performance regardless of the weather conditions. But if you want to release you from the constraints related to the change of tyres, the “four seasons” are an alternative to consider. An unknown factor which affects the choice of tyres, however, remains to be elucidated: in conditions more extreme, how are the tyres “all-season” compared to “winter”?

The tests are held on the demanding circuit of la Ferte Gaucher. Euromaster
