Soft, medium, hard: why the fastest tyre doesn't always win

The soft gives you the best lap, yet plenty of races are won on the hard. At some Grands Prix the soft is a weapon, at others it's a trap, and it mostly comes down to the asphalt and the temperature.

Red, yellow, white

Pirelli brings three dry compounds to every round: the soft with a red stripe on the sidewall, the medium with yellow and the hard with white. The softer the rubber, the more grip it has and the quicker it comes up to temperature. The price is wear. Neighbouring compounds are usually three tenths to a second apart per lap, and one can last twice as long as the other.

The case for the hard tyre

A race is about total time, not the single best lap. The soft fades fast: a few hundredths slower every lap, and then it hits the cliff, where the grip drops away almost at once. A pit stop costs roughly 20–25 seconds, so every extra stop has to pay for itself. That's the sum the strategists are doing: how many stops, on which compounds, for the lowest overall time.

Monaco, Singapore and a cold night in Vegas

Softs come into their own on smooth tarmac with low tyre loads, especially where passing is close to impossible. In Monaco and Singapore track position is king and wear is low, so a lot gets settled in qualifying on the soft. Monaco has had two mandatory tyre changes since 2025, and teams mostly use them to protect position rather than to attack. Las Vegas is a different story. It's a cold night race, the hard struggles to get up to temperature, and the soft wins simply because it works.

Bahrain, Qatar and the fast sweeps

On abrasive surfaces and in the heat, the soft overheats and is finished within a few laps. Think Bahrain, Qatar or Barcelona on a hot weekend. That's where the medium and hard come through: slower over a lap, but they hold their pace for the whole stint. The quick sequences at Suzuka and Silverstone put huge load through the sidewalls and punish the soft as well.

Spotting the end of a stint

Keep an eye on when the leaders stop and on their lap times. If a driver on softs is giving away a tenth a lap to someone on hards, he'll be in the pits soon. LapRadar's Live centre shows every driver's compound and tyre age, so you can follow the strategy as it plays out.
