F1 official tyre manufacturer Pirelli wants a return to tyres with a “cliff” from 2023, saying that the current ones are difficult to mass-produce.
Back in the day, Pirelli’s tyres had a certain mileage set for performance over the course of a Grand Prix, or a ‘cliff’. If a car goes above it, the performance would severely deteriorate.
The current tyre profile sees the company cater to cars with different wear capacities by modifying the tyres. As a result, their job becomes that much harder, having to please contrasting demands for the same set of tyres.
As a result, Pirelli wants a return to tyres with a “cliff” from 2023, saying that they would also like to have their burden reduced over the course of a season.
Speaking to GPFans, Pirelli Head of Motorsport Mario Isola said, “The only possibility is that we design a tyre which, at a certain point, has a cliff.
“We design a tyre with a mileage and if you go above this mileage you have a cliff in the performance.
“You can understand it’s not easy. Each car is different, each car has a different wear profile, each driver has a different driving style. If you put in the same document all those targets, they are not easy to achieve.”
“We focused more on overheating reduction, wider working range, and a level of degradation and delta lap time that is in line with the target letter,” Isola continued.
“For this year, our priority will be working on the cliff and fine-tune the product according to what we experienced on track because we tested the new compounds with the mule cars.
“Also, the numbers that we got from the mule cars are not 100 per cent the numbers that we will find on the new cars.”
