All Season Tyres
All season tyres are tyres that, as the name suggests, have a tread pattern suitable for use all year round. They have a tread pattern that is more heavily siped than a summer pattern but not as heavily siped as an out and out winter tyre.
They will provide perfectly adequate performance in summer conditions and may have a small amount of winter driving ability. They allow for the use of the same tyres all year round, negating the need for changing from summer to winter tyres. Not so popular in the UK where a summer tyre is generally used all year round.
