Pirelli: F1 tyre blankets ban means a completely new tyre

Formulation 1 plans to ban the use electrical tyre blankets within the 2024 season, and Pirelli head of Motorsport Director Mario Isola claims this implies new tyres need to be designed.

F1 makes use of electrical tyre blankets to pre-heat the tyres earlier than bolting them on the automobiles, however as the game heads in direction of a extra sustainable future, this follow must be banned in an purpose to scale back power consumption, in addition to decreasing the prices on the groups which is able to consequently let go of pricy gear.

The choice to ban the tyre blankets was utilized at phases, because the laws mandated a gradual discount within the temperatures used till lastly, the follow is ceased in 2024.

In 2021, the utmost temperature of the tyre heaters was decreased to only 100°C on the entrance and 80°C on the rear. At present solely 70°C temperatures are allowed for all slicks whereas the variety of blankets was decreased from 40 to twenty.

This gradual plan to take away the follow of tyre blankets is just not haphazard, as Pirelli’s Motorsport Director Mario Isola to Auto Motor und Sport defined the the explanation why such a technique was adopted.

“If you wish to drive with out electrical blankets, it’s a must to design a totally new tyre,” he started. “It’s not sufficient merely to construct new compounds with a bigger working vary.

“The Formulation 1 automobiles are so quick and generate such nice forces that the pressures improve by ten to 12 PSI whereas driving. This adjustments your complete profile and speak to space of ​​the tyre,” Isola identified.

Formulation 2 banned tyre blankets, however can’t be in contrast with F1

Whereas tyre blankets are now not is use in Formulation 2, Isola claims their may be no comparability between each F1 and its feeder collection, as the rise of stress from when the tyres are bolted on the automobiles and as soon as they’re loaded by the driving is larger in F1.

As a word, F2 tyres are inflated to a stress of 13-15 PSI earlier than being bolted on the automobiles. That stress rises to twenty PSI in driving circumstances

“The rise in stress is twice as excessive as in Formulation 2,” Pirelli’s Motorsport boss estimates. “Due to the excessive hundreds, we will’t simply begin with 15 PSI in Formulation 1. Then the drivers must take it straightforward at the start of a stint and solely slowly improve the tyre temperature.

“In fact, that doesn’t work in a race. So that they have to begin at 20 or 21 PSI. The stress then rapidly climbs to over 30 PSI,” the Italian identified.

When Pirelli examined their new-for-2022 18″ low profile tyres, simulations had been executed with decrease tyre blanket temperatures used, as 2023 will see an additional drop in blanket temperatures to 50°C, earlier than the total ban of 2024.

These simulations are the rationale why this 12 months’s tyres haven’t brought about main issues in response to Isola.

“Subsequent 12 months, the temperatures of the electrical blankets will proceed to fall – to only 50°C back and front,” Isola mentioned. “This additionally will increase the stress variations inside the stints.

“We intentionally solely take small steps in order that nothing goes unsuitable and the present suffers. The tyres work very properly this 12 months. In fact, it ought to keep that method even when we put off the electrical blankets altogether,” he insisted.

Tyre testing essential

Pirelli to decide tyre allocations for F1 teams in 2022

Pirelli want F1 automobiles from the present crop to check the tyres with all of the anticipated adjustments, and with a 24-race season confirmed for 2023, the work load can be much more on the Italian tyre provider who solely provide tyres in F1.

Nonetheless Isola is comfortable that FP2 classes can be prolonged by half-hour to permit for tyre prototypes testing, as F1 plans to trial the brand new format in Austin this 12 months.

“We’d like automobiles of the present era. Now we have to go to totally different tracks the place the tyres are subjected to totally different hundreds. And we’ve got to drive in numerous circumstances,” he mentioned.

“The concept of ​​utilizing the FP2 for testing is definitely excellent,” the Italian admitted. “The groups don’t need to journey to a observe or keep longer after a race weekend. However as quickly as you have got a brand new good thought, the groups discover issues.

“They complain that they’ve to make use of the identical automobiles and the identical engines as the remainder of the weekend. Mileage rapidly turns into a problem,” he warned.

With totally different automobiles in F1 having totally different efficiency, Isola advises that every one groups take part in tyre assessments in order that Pirelli can perceive how the tyres behave with totally different ranges of downforce.

“The quick automobiles put the tyres below extra stress,” he mentioned. “Now we have to make sure that the warm-up course of additionally works with the slower automobiles. And that the tyres don’t overheat within the quick groups.

“That’s the place we’ve got to discover a good compromise in order that the tyres work with all ten automobiles, all 20 drivers and on all tracks. It’s not going to be that straightforward,” Isola maintained.
