There are some things you need to bear in mind when driving on brand new tyres. The tyre surface will feature a number of tiny vent holes from the moulding process. It will also be incredibly smooth.
To remove these holes and properly prepare the surface for day-to-day driving, we suggest tyres should be run in for the first 150 to 200 miles at medium speed on dry roads. All while avoiding sharp cornering and hard braking.
Then, a new tyre should be ready to offer you maximum grip and optimum performance. All new tyres (especially mud & snow tyres) should be run in for the first 150 to 200 miles at medium speed on dry roads, in order to abrade the tread surface. There are several reasons for doing this:
This also explains why new mud and snow tyres must be fitted before the first snowfall, in order to abrade the surface of the tread.
If tyres have been changed to new wide tyres, cautious running in is doubly important as this also provides the added opportunity of acclimatising to the different handling on wide tyres.
