Tyre in Formula One

In motorsport, tyres are one of the most important component that affect the engine performance on track. The tyres are the only contect patch between a car and the ground. A little change on the tyres can greatly influence the performance of a racecar, especially Formula One car.

The official Formula One tyres supplier, Bridgestone, produces about 50.000 tyres in a seasons. Before producing, Bridgestone tyre engineers have to design the compound of the tyre in order to get the best tyre for race. A good tyre should have a strong grip with the ground. To get more grip, the engineers add more rubber into the element of the tyres. Wide tyre also could maximize the grip of tyre.

To compensate for lost footprint area in F1 tyres, the tyre engineers are designing the smaller diamater tyres with more flexible sidewall so more tyre will come in contact with the track. Judging from this knowledge, it is wise to choose a tyre with a taller carcass when running on a track with a rough or bumpy surface so the stiffer sidewall will help cope with the bumps and irregularities.

Almost all of the tyre parts are coloured in black. It comes from the carbon black. It's the best reinforcement for the rubber and makes the tyres black. Actually, there are also some different colour reinforcement, either blue or red, but it's not as strong as carbon black so that's why F1 tyres are black.

After designing the tyres, Bridgestone produces the tyres. Then, the produced tyres will be sent to the F1 teams a day before the practice day.

Before starting a race, the car engineers from each team always cover the F1 tyres with black blanket called tyre warmer. It could set the temperature of the tyres up to 100 degrees Celcius. They warm the tyres in order to get more grip from the heated tyres. The tyres will become very hot. Then there is a joke around F1 engineers, if you hungry, just fry an egg on the tyres.

In the end of the race, some of the used tyres are examined by team engineers and some of them are shipped out to Bridgestone factory, Japan, to be burnt in one of the factory facilities.
