Pirelli™ Formula 1® 2026 • Rear • 375/35 R18 • (Real World Details)

In 2026, Formula 1 will introduce narrower tires designed to complement the smaller, lighter cars. The front tires will be reduced by 25mm in width, and the rears by 30mm. The 18-inch wheel diameter will be maintained, despite initial considerations to reduce it. These changes are part of a broader set of regulations aimed at improving racing and sustainability.
