F1 is the only major racing series that still uses electric blankets to warm up the tires. However, from 2024 these are abolished.
The decision had been made for some time. The F1 andthey had jointly agreed to abolish them in four stages. The first was last year, when the maximum allowable temperatures were 100°C for the front and 80°C for the rear tyres. This year, temperatures dropped to 70°C back and forth.
The side effects of this change were mainly seen during the first games of the season. You will then remember the complaints of most drivers after pit-stops about the very cold tires which gave them little grip. However, teams and drivers did not take long to adapt to this new condition.
For 2023 the maximum pre-heating temperature on the front and rear tire surfaces will drop to 50°C. Yes, next season will also be the last in which we will see her teamsto use electric tire blankets. From 2024, their abolition will be complete.
But to make this transition smoothly, there will also have to be changes in the way tires are manufactured. As Pirelli’s racing director explains,: “Just new compositions are not enough. The forces exerted on the tires by an F1 car are so great that their pressure increases by 10-12 psi over the course of a stint. The profile and contact surface of the tire with the road surface changes”.
Tests during the three days of competition
With the 2023 calendar consisting of 24 Grands Prix, the next F1 season will be the longest in the sport’s history. This fact, fatally, limits the available testing time for tire development. Isola emphasizes: “Of course, during the European season we will be able to ask some teams to stay on track for a few days after a GP to test our tires. But that won’t be easy when they have to travel to games outside of Europe.”
So, according to Isola, the resulting solution is in several three-day races to make provision for tire tests during Friday. In particular, it is proposed to extend FP2 by 30 minutes. During this time all the teams will be testing the new Pirelli tires.
“The challenge of making a tire that suits all 10 teams is great” believes Isola. “There may be complaints about PUs being more stressed, but I believe we will find the golden ratio. But I think extending FP2 in some races is a very good idea” adds the Italian. The extra half hour in FP2 will be applied this year toin Austin.
