The FIA has laid down detailed specifications for the
        F1 tyres. Teams have to follow these rules while using Formula 1 tyres.
         
        Single Tyre Supplier
         All teams in Formula 1 use identical Bridgestone rubber. This reduces
        testing and development costs. 
         
        Specifications of Tyres
         Every team has access to two specifications of dry-weather tyre. The
        drivers have to use both specifications during the race. During a race
        weekend, every driver has access to 14 sets of dry weather tires, four
        sets of wet weather and three sets of extreme weather. 
         
        Extreme Weather Tyres
         During qualifying and the race, teams are free to use wet or extreme
        weather tyres. But, during the practice, they can only be used if the
        track has been declared wet. If the heavy rains force the race to start
        behind the safety car, teams have to mandatorily use extreme weather
        tyres. 
         
        Road Tyres and Race Tires
         Road tyres are made for durability. But race tyres are built for short
        races. While road tyres are made with heavy steel-belted radial piles,
        tyres of the race car are made light and strong. Race tyres are more
        tolerant that road tyres. Very soft rubber compound is used to make
        racing tyres. 
 The FIA has specified the rules governing the
        use of tyres in Formula 1. Find out how the tires are used in F1
        championships.
