F1 sees the decrease of the size and weight of cars as one of the most important factors in improving entertainment, and wheelbases will be shortened by 30cm, with gearboxes and power units also being made lighter.

In order to keep up with this trend, and ensure the cars are running on the right-sized tyre, Isola has revealed his plans to decrease the size and weight of tyres heading into the new era.
“In 2026, we have a completely new car, probably a new tyre size,” Isola told select media. “Smaller, lighter tyres, it’s possible.
“It’s not defined yet, but the target is not a secret: that is to design lighter cars, more agile cars and tyres are a part of the weight of the car. So, it can be that we have to supply smaller tyres.
“If we have to supply smaller tyres as we did in the past, we will change again in 2026. It’s part of our agreement with Formula 1 to follow the request of the stakeholders to design a tyre that is always in line with the target defined by all the stakeholders.”
