The Tire Compound Ranges Used In F1: Soft, Medium, And Hard May Not Mean What You Think

In nan high-strung world of Formula 1, immoderate of nan astir important parts of a multi-million-dollar title car are, without a doubt, nan tires. These 4 mini patches of rubber are solely responsible for transmitting each nan power, braking, and insane cornering forces to nan track. As F1's exclusive supplier, Pirelli has nan unenviable occupation of creating tires that are some reliable capable to past unthinkable reward and capable to deliberately degrade, forcing teams into nan benignant of strategical gambles that make for awesome television. Basically, they're nan only portion of nan car you're actively trying to destruct — conscionable slow capable to make it interesting.

Pirelli's lineup of color-coded tires — nan reddish Soft, yellowish Medium, and achromatic Hard — seems elemental enough. But nan truth is, those labels are a monolithic oversimplification. The reality is simply a analyzable crippled of rubber compounds, wherever a Soft tyre astatine 1 way tin beryllium nan Hard tyre astatine nan next. This is nan cardinal to deciphering nan strategical chess lucifer of a Grand Prix weekend, and realizing that what you spot connected nan sidewall doesn't ever show nan full story.

While you'll only ever spot 3 barren tyre options connected immoderate peculiar title weekend, Pirelli's existent catalog runs deeper. For 2025, they've expanded their scope to six different dry-weather compounds, branded Compound 1 to C6. Think of nan "C" arsenic opinionated for "Compound," pinch C1 being nan astir durable, rock-hard action and C6 being nan ultra-sticky option.

This scope is simply a deliberate move by Pirelli to springiness itself much devices to messiness pinch title strategy. The C1 and C2 are nan endurance runners, built for high-speed, high-energy tracks for illustration Silverstone and Suzuka, wherever tires are tortured. The C3 is nan versatile workhorse of nan group, nan jack-of-all-trades that tin play immoderate domiciled depending connected nan venue. The C4 and C5 are nan grippier, faster-wearing options, designed for slower circuits wherever grip is king.

Then there's nan newest sibling, designed pinch thoroughfare tracks successful mind — nan C6, Pirelli's cotton-candy compound that vanishes faster than Nakita Mazepin's career. It's absurdly soft, deliberately fragile, and tailor-made to create much robust strategy options alternatively of just one-stoppers astatine places for illustration Monaco. In Pirelli's ongoing warfare connected boring processions, this is nan atomic option: a tyre not built to last, but to grip for illustration hell. Fans telephone it strategy. Critics telephone it theater. Either way, it lets F1 add clone play to races erstwhile nan cars aliases tracks themselves can't nutrient breathtaking racing.

Here's 1 of nan least-known things successful F1: nan red, yellow, and achromatic sidewalls are conscionable comparative labels, not fixed tires. For each race, Pirelli picks 3 compounds from its C1-C6 scope and simply calls nan softest 1 "Soft," nan mediate 1 "Medium," and nan hardest 1 "Hard." 

The versatile C3 compound is nan cleanable illustration of this successful action. At a high-energy way for illustration Barcelona, Pirelli brings its hardest tires: nan C1, C2, and C3. Here, nan C3 is branded arsenic nan red-walled Soft tire. But recreation to a thoroughfare circuit for illustration Jeddah, and Pirelli mightiness bring nan C3, C4, and C5. Suddenly, that very aforesaid C3 compound is now nan whitewalled Hard tire, nan astir durable action disposable for nan weekend.

This is really Pirelli choreographs nan chaos, 1 compound astatine a time. For nan 2025 Belgian Grand Prix astatine Spa, it's going off-script pinch a "gapped" compound action — bringing nan C1, C3, and C4 while deliberately skipping nan C2. That move creates a monolithic no-man's-land betwixt nan Hard (C1) and Medium (C3), turning nan Hard compound into nan balanced of betting connected double zero astatine nan roulette array — technically an option, but a risky one. It's not subtle: this is Pirelli steering teams toward fierce two-stoppers, proving erstwhile again that it's not conscionable supplying tires — it's actively shaping nan race.

When nan heavens open, teams move to Pirelli's treaded Cinturato tires, which travel successful 2 flavors: Intermediate and Full Wet. The green-walled Intermediate is for damp aliases drying tracks and is an engineering marvel, tin of displacing astir 10 gallons of h2o per 2nd astatine speed. That intends a azygous F1 car astatine velocity is clearing astir 40 gallons of h2o from each 4 tires— astir a afloat bathtub — each second.

For heavier downpours, there's nan blue-walled Full Wet, which tin displace a mind-boggling 20 gallons per second. But here's nan classical F1 paradox: nan Full Wet is truthful effective astatine its occupation that it creates a secondary problem. The monolithic plume of spray it kicks up wholly blinds pursuing drivers, making racing dangerously difficult. It's a cleanable illustration of F1 engineering solving 1 problem truthful good that it creates an wholly caller one. It's nary wonderment these Full Wets are surprisingly awesome for off-roading, arsenic well.
