Istanbul’s Turn 8 Won’t Challenge Tyres More Than Silverstone, Pirelli Confirms

The highly anticipated return of Formula 1 to Istanbul Park for the Turkish Grand Prix has ignited significant discussions, particularly concerning tyre performance and safety. Following a challenging weekend at Silverstone earlier this year, which saw multiple tyre failures, Pirelli, F1’s sole tyre supplier, is expressing confidence that the unique demands of Istanbul Park, including its iconic high-speed Turn 8, will not pose the same severe risks. This cautious optimism stems primarily from the circuit’s recent resurfacing and extensive simulations conducted by the Italian tyre manufacturer.

Pirelli’s Optimism: Navigating Istanbul Park’s Challenges

Tyre integrity was a major concern following several failures at Silverstone

The Turkish circuit, renowned for its challenging layout and specifically the quadruple-apex Turn 8, has been meticulously resurfaced ahead of this weekend’s much-anticipated race. This crucial development is expected to fundamentally alter the demands placed on the Pirelli tyres, offering a different dynamic compared to previous visits. Mario Isola, Pirelli’s head of motorsport and F1, highlighted the meticulous preparation and analysis undertaken by the company.

“Talking about the severity of the circuit, we made some simulations and we have an idea. Obviously, the severity of Turn 8 is something that we know, but we now have a good metric for us to compare circuits,” Isola explained. “So we made a comparison between Istanbul and some other high severity circuits; to give you an idea, in general Istanbul is less severe than Spa and Silverstone. So we are not talking about a circuit that has a higher severity compared to circuits that we know better.”

The implications of the new tarmac are profound. Isola elaborated on the surface characteristics: “The tarmac is new and actually we went there. Thanks to our people in Turkey, we had the chance to use a laser and measure the asphalt. It is quite smooth, it is very new. If I have to give you an idea of the behaviour that I am expecting, it is probably quite in line with what we have seen in Portimao.”

The comparison to Portimao is particularly telling. The Portuguese Grand Prix, also held on a newly resurfaced track, presented its own set of challenges, with drivers reporting a lack of grip and difficulties in generating tyre temperature. While Istanbul’s surface might share the smoothness, its inherent layout, especially the legendary Turn 8, ensures a unique test for tyre construction and compound resilience.

Understanding Turn 8 and Tyre Demands

Turn 8 at Istanbul Park is a legendary corner in Formula 1 history, often compared to the challenges of Eau Rouge or the demands of Suzuka’s Esses. It’s a long, sweeping left-hander with multiple apexes, subjecting tyres to immense and sustained lateral forces. Drivers spend several seconds navigating this turn at very high speeds, which builds up significant heat within the tyre structure and places considerable stress on the sidewalls. In previous years, this corner was a prime location for tyre degradation and wear. However, with the new, smoother tarmac, the abrasive forces might be reduced, but the challenge of finding optimal grip and managing heat build-up will shift.

The resurfacing means a smoother surface, which often translates to less mechanical grip initially. This can make it harder for drivers to get heat into the tyres, particularly if ambient temperatures are low. Yet, a smoother surface can also reduce graining and blistering in the long run, offering a different challenge to tyre engineers and strategists. Pirelli’s confidence, therefore, suggests their simulations account for this altered surface, predicting a less aggressive interaction with the rubber compared to the more abrasive Silverstone circuit.

Lessons from Silverstone and Portimao

The British Grand Prix at Silverstone earlier in the season was marred by late-race tyre failures, prompting an immediate investigation by Pirelli and significant concern within the paddock. The failures were attributed to a combination of extreme loads on the tyres, high speeds, and the specific characteristics of the circuit. Pirelli subsequently revised tyre pressures for subsequent races and implemented stricter guidelines.

The experience at Portimao with its new tarmac also provided valuable data. Drivers struggled with low grip, leading to a spectacle of sliding cars and a strong emphasis on managing tyre temperature and wear. If Istanbul Park’s new surface behaves similarly, teams will need to quickly adapt their setups to generate optimal tyre performance, balance grip with degradation, and potentially manage a cooler track surface than previously experienced at the circuit.

Pirelli’s assessment that Istanbul is “less severe than Spa and Silverstone” for tyres offers a level of reassurance. Spa, with its high-speed compressions and long straights, and Silverstone, with its sustained high-speed corners, are known as two of the most demanding circuits for tyres on the F1 calendar. By classifying Istanbul below these in terms of severity, Pirelli indicates that while demanding, the new surface characteristics combined with their latest tyre constructions should provide a robust and safe racing environment. Teams will still face complex decisions regarding tyre compounds and race strategy, but the overarching concern of structural integrity seen at Silverstone appears to be mitigated by Pirelli’s comprehensive analysis and the circuit’s updated surface.

The 2021 F2 calendar is a good example of why alternative series are a positive. If there were market forces at play (eg FR3.5) there is no way that schedule would be proposed let alone a reality

Comment of the Day: Navigating the 2021 F1 Calendar’s Demands

GT Racer raises a pertinent problem for the 2021 F1 calendar, highlighting potential burnout for many involved in the sport, especially after a late-running and exceptionally intense 2020 season:

“When they tried that triple-header in 2018 everyone in the paddock universally agreed it was too much and they shouldn’t do it again. This year they were forced to due to the pandemic and again concerns were raised regarding it been too much.”

“Yet next year they have two triple-headers. I can see that going down exceptionally badly with the crews as well as FIA and FOM staff who have to attend races as well as broadcasters who universally felt triple headers shouldn’t be done again.”

“I can see a lot of very burnt-out people around F1 at the end of next year.”
