Can you mix winter and summer tyres on the front and rear?
Legally, this is not forbidden, but it is not what the Michelin experts recommend. Why not? Because road and weather conditions can cause tyres to behave differently.
For example, if you put summer tyres on the front and winter tyres on the rear: in winter, your rear tyres will grip well and you will not risk a spin.
On the other hand, in summer it will be the other way round: the summer tyre will grip better on dry roads and there will be a risk of "oversteering" with winter tyres on the rear. Oversteer is when the car turns more than it is told to do with the steering wheel: it is the beginning of a spin.
It is therefore not recommended to fit different season tyres at the front and rear, but if this is the case, it is preferable to fit summer tyres at the front and 4-season or winter tyres at the rear.
