In Formula 1, tire suppliers such as Pirelli provide different tire compounds with varying levels of grip and durability to teams. These compounds are labeled with different names, such as soft, medium, hard, and occasionally, ultra-soft. The ultra-soft tires are typically the softest and provide the most grip, but they can also wear out more quickly than harder compounds.
To stay up to date with the latest developments in Formula 1 and tire regulations, I recommend referring to reliable sources, such as official Formula 1 websites, motorsport news outlets, or the Pirelli tire company, which is the current tire supplier for Formula 1.
