Goodyear demonstrates the importance of winter tyres
Winter tyres or summer tyres? Following the event held by Goodyear at the ice-driving circuit in Tignes to highlight the challenges of winter driving, Rezulteo recaps of the advantages of winter tyres for those of you who remain unconvinced.

At over 1500 metres of altitude, the Tignes ice-driving circuit is located in a hollow just after the dam in the hamlet of Brevières. It gets very little sunlight, which makes it perfect for maintaining stable conditions while the manufacturer Goodyear takes us through a series of tests.
Winter tyres vs. summer tyres
The first three test run we took part in were designed to compare winter tyres and summer tyres.
We kicked off with a hill start on a gentle slope. The driveability of the Peugeot 308 fitted with EfficientGrip Performance summer tyres (205 55 R16 91V) was non-existent compared to the UltraGrip 8 winter tyre (205 55 R16 91H): a simple, but highly effective demonstration. This was followed by an obstacle avoidance test. This was simulated using a sign which randomly displayed which direction the car should take at the very last minute. At 50 kmph, the Citroën DS5, fitted with EfficientGrip Performance (225 50 R17 98V), found it simply impossible to brake and avoid the obstacle in time. At the point at which we expected the car to stop, it continued sliding for several more metres, knocking down the cones in its path. The other DS5 was fitted with UltraGrip 8 Performance in 225 50 R17 98V. See demonstration video:
So what happens if you just fit two winter tyres at the front?
We’ve said it before but we’ll say it again: two winter tyres at the front are just not enough. Not only are they bad value for money, the behaviour of the car is just ridiculous. The oversteering you get every time you so much as touch the steering wheel or the brakes makes the car even more dangerous than with four summer tyres!
But don't just take our word for it, judge for yourselves:
3PMSF tyres VS M+S tyres
The last workshop in a Jeep Grand Cherokee compared the braking performance of a M+S tyre (Dunlop GrandTrek AT20) and a 3PMSF winter tyre: the Dunlop SP Winter Sport M3. At a cruising speed of 45-50 kmph the Grand Cherokee fitted with M+S tyres took an extra 20 metres to come to a stop, compared to the jeep fitted with winter tyres. Using the onboard brake monitoring system we simulated the braking performance at 80 kmph which resulted in an average difference of over 20 metres.
