The Italian firm – who has supplied F1 tyres since 2011 then inspects the returned rubber for any cuts or defects and other general analysis. They are then shipped back to the UK, crushed and sent off to a factory. The rubber is then burned at high temperature (not incinerated) to create energy.

How many times can F1 change tyres?

Why did old F1 tires have grooves?

Between 1999 and 2008, regulations required the tyres to feature a minimum of four 14 mm (0.55 in) grooves in them, with the intention of slowing the cars down. This is because a slick tyre, with no indentations, provides the most grip in dry conditions.

Why are F1 tires so smooth?

F1 tires have no treads because it makes them faster. The more contact the rubber has with the tarmac, the more traction it gets, which increases the speed and ability to corner properly. Therefore, using tires with no treads makes a lot of sense in a sport solely centered around making the cars as fast as possible.

Are Formula 1 tires solid?

Street car tyres are steel reinforced within the rubber, while F1 tyres have a nylon and polyester base structure that enables them to handle heavier loads and forces. Due to the huge forces, the wear is very high and the rubber gets lodged on the track surface.
