Tread pattern and compound

The tread pattern is the outer part of the tyre and in contact with the road.
The profile and rubber compound are chosen based on the use of the tyre. The rubber compound requires a high level of experience and technical know-how. In general, with a harder rubber compound, mileage increases and grip decreases. The softer the rubber compound, the more grip a tyre has - but the mileage is reduced.
