Summer tyres versus winter tyres: Michelin's snow test

Winter tyres Published the 15/02/2013 by Peter

Did you know that a summer tyre travelling at 25 mph needs more than twice the distance to stop on snow than a winter tyre? Rezulteo has checked this out by participating in tests organised by Michelin on the Val-d-Isere track in Savoie (France).

For starters, here are a few reminders:

 

The qualities that winter tyres offer are more visible on snow-covered roads. This has been proven beyond doubt in tests conducted by Michelin on the Val d'Isere track in Savoie.

Braking test

Vehicles used: BMW 1-Series

Tyres used: Michelin Alpin and the Michelin Primacy 3

Dimensions: 205 55R16

Surface: Packed snow

Test conditions:  A low speed rolling start in first gear and gradually accelerate to drive up a slight slope.

Result: The braking distance of the car fitted with summer tyres is twice as long as the vehicle fitted with winter tyres. The Primacy 3 offers virtually no snow traction, the car is unable to maintain directional stability and active safety is greatly affected. With the Alpin 4, you enter another universe. The car is balanced, efficient and safe.

Traction test

Vehicles used: BMW 1-Series

Tyres used: Michelin Alpin and the Michelin Primacy 3

Dimensions: 205 55R16

Surface: Packed snow

Test conditions:  A low speed rolling start in first gear and gradually accelerate to drive up a slight slope.

Result: On a rear wheel drive vehicle, such as the BMW 1-Series, there is a significant lack of grip. Fitted with summer tyres, it is almost impossible to move the BMW. Each start implies just the right amount of pressure applied to the accelerator. However, this is not a problem for the Alpin 4. In this exercise, the Alpin 4 has a clear advantage over the Primacy 3.
