Tyres must meet many, very different requirements: grip in all driving and weather conditions, durability, and comfort when running. Modern tyres have a radial construction (radial tyres) and today all are tubeless. The belt made of steel or textile fibres forming the carcass gives the tyre stability.
The tread consists of a complex mixture of different materials whose most important constituents are rubber and carbon black. In line with American and European standards, tyres bear prescribed labelling that gives information about type, size, maximum running speed, age and manufacturer.
The different climatic conditions in different seasons require specialized types of tyres for optimum driving safety in central and northern European latitudes. This is why manufacturers offer special summer and winter tyres which differ fundamentally as regards the design of the tread and the material mixture in order to meet the requirements of the respective seasons.
Wide tyres enhance the optical appearance of a car and on dry pavement improve power transmission, cornering stability and deceleration. SEAT equips its new cars with certified brand tyres that meet the high safety standards, generate minimal road noise and guarantee a high degree of driving comfort.
