Abstract
The invention relates to a tire suitable for all-year-round use comprising a tread profile in which--looking in the running direction--one half of the tire is formed from profile blocks separated from one another while the other half of the tire has a substantially continuous profile interrupted only by lamellae. The two halves of the tire are best made of different rubbers of which the properties are adapted to the particular tread profile.
