With such feats of mathematical and mechanical

They are, after all, a race car's biggest single performance variable.

The tyres on race cars are similar to those of road cars in name and little else. Road tyres are designed to last for thousands of miles, with strength and durability key factors. Racing tyres, on the other hand, use much softer compounds in order to offer the best possible grip against the racetrack. However, it is because of this that they break down very quickly, lasting only 125 miles at the very most.

Race tyres are meant to be light and strong, maximising the speed of the car by not weighing it down. They also need to withstand much greater downward force than the typical road tyre - often up to a tonne - and as a result, are made differently, utilising a weave of nylon and polyester as opposed to the road tyres' steel-belted radial piles.

'Slicks' were used from the 1960s, until a rule came into force in 1998 banning them. Developers found that in having 'slick' tyres (i.e. ones with no tread on whatsoever) for use in dry weather, the surface area was maximised and more of the tyre would be touching the road, therefore allowing drivers to take corners much faster.

The rule in 1998 was brought in to improve the spectacle of Formula 1, by slowing down the speed in which drivers took the corners. However, the rule was revoked in 2009 when the Federation Internationale de l'Automobile (FIA) opted to limit aerodynamics as opposed to tread.

Finally, just as imporatnt as the tyres themselves is what goes into them. To minimise variations in tyre pressure with temperature (which can affect the performance of the vehicle greatly), a nitrogen-rich air mixture is used. Not only does this minimise fluctuations in tyre pressure, it also retains the pressure much longer than normal air would.
