Formula 1 Tires: The Ultimate Beginners Guide & Reckoner
Key Takeaways
- Formula 1 tyres are extremely well-designed components that affect performance in terms of speed, traction, strategy, and race results.
- There are various types of tyres used in racing cars according to their properties, ranging from hard to soft slicks as well as wet weather tyres depending on track conditions and temperature.
- Drivers must use at least two different dry tyre compounds during a race, making at least one pit stop mandatory.
- Proper tyre management is very important in Formula 1.
- Dry "slick" tyres feature no grooves to maximise surface contact, whereas wet weather tyres use specialised grooves to disperse up to 85 litres of water per second.
The tyres are one of the most crucial parts of a Formula One car; they're the only thing touching the ground (unless something goes wrong) and have team strategists and drivers puzzling over which ones to use. It's not just about dry or wet conditions!
For most races, the strategy team already knows what compounds they'll use in which sessions and for how many laps. This depends on a bunch of things, like the roughness of the track, the track temperature, and the weather. You often hear commentators say the driver needs to 'get heat in the tyres', but it's not just about getting them hot for more grip; each compound has an ideal temperature.
If they get too hot, there's a lot of degradation, the tyres can blister, and pieces of rubber might fall off. If they're too cold, the tyres can develop 'grainings', a braided-like surface that increases wear and degradation. Tires have a sweet spot, and the temperature affects whether they hit that sweet spot or miss it. So, that's the lowdown on the tyres. Now, let's talk about the different Pirelli compounds.
Supplier of Formula 1 tyres
The present manufacturer of the Formula 1 tyres is an Italian company known as Pirelli. Pirelli has been the only supplier since 2011 following the exit of a Japanese firm called Bridgestone. Pirelli's contract with the FIA and Formula 1 will be ending after the 2024 season.
There have been a total of nine tyre manufacturers in the history of Formula 1 racing; these include Avon, Bridgestone, Continental, Dunlop, Englebert, Firestone, Goodyear, and Michelin. Goodyear (1959-1998) holds the record for most wins with 368.
F1 Tire Tactics
Formula 1 tyres are very advanced pieces of equipment. The teams should always consider the usage of these items carefully since a single mistake, such as choosing inappropriate tyres or forgetting some tyres, can spoil the performance of the driver during the whole race. Is that crazy?
However, it is not surprising! Just remember Ferrari, which cost Carlos Sainz more than 12 seconds in the Dutch Grand Prix of this year. The driver who was in third place dropped to sixth place due to the fact that his mechanics had just three tyres instead of four. Then, Sainz received a 5-second penalty for unsafe release and finished eighth. Sounds ridiculous? Any F1 team can make similar errors.
Drivers pick a certain tyre compound to start with and quickly realise it was the wrong move. Or they switch to wet or dry tyres too early or too late as the weather changes. Or they don't accurately predict how fast different tyres will wear out during the race. There's a lot more to it than just slapping on four new tyres during pit stops.
F1 Tire Usage Rules
Each Formula 1 team receives 13 sets of dry tyres for each race weekend: 2 hards, 3 mediums and 8 softs. The team will receive 4 sets of intermediates and 3 sets of full wets. Should it rain in Friday FP1 and FP2 or Saturday FP3 practice sessions, teams will receive one extra set of intermediates, but they should give back one used set prior to the qualifying session.
In the past, drivers who qualified for the third stage of qualifying (Q3) had to start the Sunday race using the same set of tyres that helped them qualify for Q3. The drivers who were not in the top ten could choose whichever tyres they liked. But now, under the new 2022 rules, all the drivers who qualified for Q3 will start the Sunday race on any tyre compound that they like, just like the rest of the grid.
In dry races, the drivers must use two different compounds, which means at least one pit stop is required. That regulation does not apply in the case of wet races. If the race starts behind the safety car due to rain, drivers must use wet tyres. They may change them to dry ones during the first pit stop if the rain stops.
Wet Tires Include Blue and Green
So, there are two kinds of wet weather tyres: green-marked intermediate ones and blue-marked full wet ones. You'd use the intermediates when the track is just a bit slick, or there's a light drizzle. The full wet tyres come into play when it's pouring or there's standing water all over the track.
Full Wet Blue
Full-wet tyres are your best bet for heavy rain. They can clear out 85 litres of water per second per tyre when you're going 300 km/h. There's a new design that helps prevent aquaplaning, so you'll get better grip when it's really coming down. These tyres are also 10 mm wider than the slick ones.
Green Intermediate
Intermediate tyres are pretty flexible for rain. You can use them on a wet track without standing water or even on a drying surface. These tyres can clear 30 litres of water per second per tyre at 300 kph. There's a new compound that helps them work well in a variety of conditions, making sure they transition smoothly between slicks and full wets.

Dry Slick Tires Include C1-C5
Alright, before we dive in, just remember: softer tyres are faster, but harder tyres last longer. Let's break down the dry compounds:
- C1: The hardest tyre out there. Perfect for tracks that really wear down tyres, like Silverstone and Suzuka. These can go for ages without losing much performance and are super resistant to heat and extreme forces.
- C2: The second hardest. Good for high-speed tracks with lots of heat and energy. Also a solid choice for new tracks where track wear is a mystery.
- C3: A great all-rounder. Works well in a variety of conditions and can be used as the softest, hardest, or medium compound.
- C4: Designed for tight, twisty tracks where you need a quick warm-up. This year, Pirelli picked these as the mediums for Monaco and the softest for Miami and Emilia Romagna.
- C5: The softest and fastest. Best for tracks needing max grip, like street circuits such as Monaco, which is super slow and twisty.
Comparing Wet & Dry Tires
The hard, medium, and soft tyres for dry races are called slick tyres. No grooves or patterns, meaning more rubber hits the track for better grip and faster racing. In wet conditions, the intermediate and full wet tyres have grooves to channel water away. The green intermediate tyres are the most versatile for rain, handling 30 litres of water per second at 300 kph. The full wet tyres are heavily grooved and can handle 85 litres of water per second at 300 kph.

Conclusion
It is important to understand Formula 1 tyres in order to gain a more in-depth understanding of the intricacies associated with the sport. Tires are not simply circles of rubber; they are advanced parts that help determine the outcomes of races.
Be it the many compounds available from Pirelli or the decision teams have to make about tyre strategies and pit stops, there are many factors about Formula 1 tyres that should be understood. Beginners who are new to the sport will get much out of learning about tyre types, their different compounds, and performance characteristics.
FAQs
1. Why are tyres an essential part of F1 racing?
Since tyres represent the only part of an F1 vehicle that touches the ground, they make tyres extremely important for F1 cars, as they play a role in providing grip, braking ability, and cornering ability of an automobile.
2. What types of F1 tyres exist?
There are two types of F1 tyres—dry-weather slick tyres and wet-weather tyres. Dry slick tyres can be hard, medium, and soft. Wet tyres are classified into intermediate and full wet tyres.
3. What is the distinction between soft, medium, and hard F1 tyres?
The soft tyres are those that have high levels of grip and faster lap times but are worn out very soon. The medium tyres represent a balance between fast lap times and tyre longevity.
4. In what situations would an F1 team use intermediate and full-wet tyres?
Intermediate tyres would be used in light rain conditions or when the track is wet but without any standing water. Full wet tyres are used in heavy rain conditions, as they help in better water dispersal and control for the drivers.
5. How does an F1 team select its tyres for a race?
An F1 team analyses various things, such as the temperature of the track, weather predictions, and tyre wear and tear rate, among others, before selecting the tyres. Data obtained during the race also plays a significant role.
