Early Tire Competition (1950s–1990s)
The Rise of Early Manufacturers
In the early days of Formula 1, tire manufacturers like Dunlop, Firestone, Pirelli, Englebert, and Continental were locked in fierce competition. Dunlop stood out during the 1950s and 1960s, becoming a key player by supplying tires to many championship-winning teams. They developed advanced tire compounds and construction techniques, especially excelling in wet-weather performance. This edge often gave teams a crucial advantage during rainy races. Firestone, on the other hand, carved its reputation with durable tire designs, making them a favorite for longer races where endurance was critical. During the 1950s, teams frequently switched tire suppliers mid-season, hoping to gain a performance edge.
Key Technical Milestones
The era brought pivotal advancements that transformed F1 tire technology. The shift from cross-ply to radial tires in the late 1960s and early 1970s improved sidewall flexibility, which increased the contact patch with the track. Another game-changing innovation was the introduction of slick (treadless) tires at the 1971 Spanish Grand Prix. These tires maximized rubber contact with the road, delivering significant improvements in cornering speeds and braking performance. These developments allowed for longer stints on track and opened the door to new race strategies. Such advancements also laid the groundwork for manufacturers to secure exclusive deals, reshaping the competitive landscape in the decades that followed.
Dominance and Exclusive Agreements
As tire technology progressed, the market began to consolidate. While the early years saw a variety of suppliers, Goodyear’s entry in 1964 marked a turning point. By the late 1960s, the American company had cemented itself as a dominant force in Formula 1. This dominance continued into the 1980s and early 1990s, during which exclusive agreements became more common. In many cases, Goodyear served as the sole tire supplier, providing stability but reducing competition. A notable exception was the 1985 French Grand Prix at Paul Ricard, where Pirelli’s tires outperformed in the scorching heat. While exclusive deals simplified the sport in some ways, they also influenced the evolution of F1’s tire regulations.
The Modern Era: Goodyear, Michelin, and Bridgestone (1997–2006)
Bridgestone's Entry and Michelin's Return
The arrival of Bridgestone in Formula 1 in 1997 shook up the status quo. The Japanese tire manufacturer capitalized on the FIA's introduction of grooved tire regulations, which disrupted Goodyear's long-standing dominance. This rule change opened the door for new competitors, and Bridgestone wasted no time stepping in. Partnering with teams like Ferrari, Jordan, and Minardi, Bridgestone brought fresh ideas to tire development, sparking technical innovation across the grid.
Michelin’s return in 2001 added even more intensity to the competition. After a 17-year absence, the French company made an immediate impact. By just the fourth race of the season at Imola, a Michelin-equipped Williams had already claimed victory, proving their ability to compete at the highest level.
The rivalry between tire manufacturers added a new layer of complexity to Formula 1. Teams now had to weigh their choice of tire supplier as carefully as their engine deals, knowing that tire performance could make or break their season. This dynamic led to a fierce technical arms race that redefined team strategies and partnerships.

The modern era of tire competition came to an end when Michelin exited Formula 1 after the 2006 season. While the intense rivalry drove innovation, it also led to skyrocketing costs and added complexity. This set the stage for the sport’s transition to a single tire supplier model, marking the start of a new chapter.
The 2005 United States Grand Prix Controversy
What Happened at Indianapolis?
The 2005 United States Grand Prix at Indianapolis Motor Speedway became infamous for all the wrong reasons. It all started with Ralf Schumacher's terrifying crash at Turn 13, caused by a left-rear tire failure. This incident exposed a major safety issue with Michelin tires, which were used by seven teams. Michelin determined their tires couldn't handle the high-speed, banked Turn 13 safely. Even after testing replacement tires, the problem persisted. As a result, Michelin advised its teams to pull out of the race. This left only six cars on the grid - all running Bridgestone tires. What followed was a surreal spectacle of a race, with fans in the stands expressing their frustration and many leaving early as the event unfolded.
Technical Causes of the Problem
The root of the issue lay in the unique design of Indianapolis Motor Speedway's Turn 13. This high-speed, banked corner created extreme lateral forces, particularly on the left-rear tires. Michelin's tire construction simply wasn't built to endure the unusual stresses generated by this corner. Even the replacement tires, which had been used earlier in the season at the Spanish Grand Prix, suffered from the same design flaws. Bridgestone, on the other hand, had developed tires with construction and compounds specifically designed to handle such demanding conditions, giving their teams a critical advantage.
Impact on F1's Reputation and Rules
The fallout from this controversy was immediate and far-reaching. The event severely damaged Formula 1's reputation in the United States, a crucial market for the sport. Fans at the track were visibly upset, with some booing, throwing debris, or leaving early. Michelin suggested adding a chicane at Turn 13 to slow the cars, but FIA Race Director Charlie Whiting rejected the idea, citing concerns about fairness in the championship.
This incident also led to significant changes in F1 regulations. The FIA scrapped the 2005 rule requiring teams to complete races on a single set of tires, reintroducing tire changes in 2006. Perhaps the most notable outcome was the shift to a single tire supplier. By 2007, Bridgestone became the exclusive tire supplier for Formula 1, ending the era of competitive tire wars and putting a stronger emphasis on tire safety.
| Impact Area | Immediate Effect | Long-term Consequence |
|---|---|---|
| Fan Trust | Booing, early departures, debris thrown | Damage to F1's reputation in the U.S. market |

| Tire Rules | Single-set tire rule in 2005 | Reintroduction of tire changes in 2006 |
| Competition | A farcical six-car race | End of the tire wars era |
The Single Supplier Era (2007–Present)
From Competition to Regulation
Following the safety concerns at the 2005 US Grand Prix, the FIA introduced a single tire supplier model in 2007. The goal? To improve safety, cut costs, and create a more level playing field.
Bridgestone held the exclusive supplier role until 2010, after which Pirelli took over in 2011 - a partnership now set to continue through at least 2027. This shift removed the need for teams to pour resources into extensive tire testing and expensive development collaborations. Unlike Bridgestone, Pirelli was tasked by the FIA with creating tires designed to degrade in a controlled manner, adding a strategic layer to races. This change not only simplified team operations but also ushered in a new era where race tactics became just as important as outright speed.
Designed Degradation and Strategy
Pirelli’s tires are engineered to degrade predictably, forcing teams to carefully plan pit stops and adjust strategies mid-race to manage performance drops.
For every race weekend, Pirelli provides up to five dry-weather compounds (C1–C5) and two wet-weather options, with each team receiving 13 sets of dry tires. The hardest compound (C1) is built for durability, while the softest (C5) prioritizes speed but wears out quickly. This system ensures tire strategy plays a central role in race planning. Teams analyze wear patterns, calculate optimal pit windows, and select compounds that align with their race goals.
While purists initially criticized this approach, longing for the raw performance focus of the tire wars, the controlled degradation model has added unpredictability. Drivers now face the dual challenge of managing tire wear and temperatures while pushing for competitive lap times - a balancing act that has redefined racecraft in modern Formula One.
Lessons from the Single Supplier Era
The single supplier model has reshaped the sport in more ways than one. By standardizing tire quality, it has improved safety, lowered costs, and leveled the playing field, giving smaller teams a better chance to compete. Success in today’s Formula One depends less on having a superior tire supplier and more on fine-tuning car setups and crafting smart race strategies.
While some argue that the lack of direct competition among tire manufacturers stifles innovation, the introduction of strategic variability - such as managing tire degradation and timing pit stops - has made races more unpredictable and, ultimately, more engaging to watch.
The model’s success has also inspired other motorsport series to adopt similar approaches, highlighting an industry-wide shift toward balancing safety, cost control, and entertainment. As the sport evolves, ongoing collaboration between teams, drivers, and tire suppliers will be key to refining tire designs and meeting new technical challenges.
