The Latest Breaking News from Mario Isola

As F1 teams have fully understood the new ground-effect regulations, they have found ways to increase the downforce and better manipulate outwash to improve their performance.

The smaller rim size was under consideration largely as part of ongoing efforts by the FIA to reduce the overall weight of the 2026 cars.

The year also saw an ultimately aborted effort to create no-blanket slicks for 2024, the successful introduction of a full wet that did work without blankets, a new construction introduced at the British GP to deal with ever-increasing downforce, and an end-of-season request from the F1 Commission to tackle the…

Drivers have increasingly complained about needing to manage overheating from the Pirelli tyres, with the rubber prone to thermal degradation, which forces them to back off in search of cooler air.

To boost the relationship between F1 technology and road cars, tyre size grew from 26.4 inches (13-inch wheel rims) to 28.3 inches (18-inch rims) for the arrival of ground effect in 2022.

Thanks to a mid-November calendar slot, and the decision to hold the charge along the famous Strip at night, the air temperature will most likely drop well below 10 degrees Celsius for all track sessions.

After Pirelli designed new 23-inch tyres for the initial switch to ground-effects last season, subsequent aerodynamic development from teams has led to complaints about how easily the tyres now overheat from the altered airflow.

The Italian company has already decided that its other tyres will remain unchanged for next year, and the Mexican running is the only opportunity to prove the worth of the revised C4.

The recent event at the revamped Losail circuit was overshadowed by tyre problems, after Pirelli discovered a microscopic separation in sidewalls following practice running.

F1’s official tyre supplier was forced to take action along with the FIA after microscopic analysis of tyres used in Qatar revealed a sidewall separation that could have led to failures.
