Pirelli has announced the tyre nominations for the final three grands prix of the year, with the medium compound the preferred choice for each of the races in Abu Dhabi, the USA and Brazil.

At Yas Marina, the teams will use the medium and soft tyres, while the relatively unknown quantity of the all-new United States Grand Prix at the Circuit of the Americas, the medium will partner Pirelli's hard compound, a combination which will also be pressed into action for the season finale at Interlagos.

The Abu Dhabi race is run in the late afternoon and evening, with falling temperatures. Although the lap takes in a wide variety of speeds and corners, the surface is quite smooth and degradation is not excessive, making medium and soft the perfect choice.

The new Austin-based CotA will be raced on for the first time, and the simulation data established by Pirelli's engineers over the summer has indicated that the hard and medium tyres will be best-suited to the varying demands of this track. During a recent visit, the company's engineers established that significant energy loads will be put through the tyres, while high temperatures are also expected, so a relatively conservative tyre choice will make sure that all possibilities are covered.

The Interlagos circuit, by contrast, is well known for being demanding on the tyres, with big elevation changes, high-speed corners and significant energy loadings going through the structure. For these reasons, the hard and medium tyres are also seen as the best choice for the final race of the 2012 season.

The medium compound has been the prevailing choice for much of the 2012 season, with only Barcelona, Monaco, Montreal, Silverstone, Singapore, Korea and India not seeing the white-ringed rubber, often in order to provide a bigger jump between compounds in the name of competition. Next weekend's Indian Grand Prix will utilise the hard and soft tyre options.
