In 1998, grooved tyres were introduced with three groove lines in the front tyres and four groove lines in the rear tyres. ![]() Goodyear would leave the sport following the 1998 season, leaving Bridgestone as the sole tyre provider for the next two seasons. įor the 1997 F1 season, Bridgestone joined Goodyear in supplying tyres to F1 competitors, creating a tyre war between the two manufacturers. This prompted Goodyear to change to yellow sidewall markings to correspond to the new, narrower rear tyres which were approximately 12.8" wide, down from the previous 15.0". For the 1993 season, the complete wheel width of the rear was reduced from 18" to 15". Therefore, from 1981 until 1992, Goodyear supplied white sidewall marked Eagle tyres with the sizes of 25.0"×10.0"-13" in the front and 26.0"×15.0"-13" in the rear. įor the 1981 season the maximum diameter of the rear tyre was limited to 26.0", while the diameter of the front tyres was increased. 1975's Ferrari 312T used a Goodyear 26.0"×16.2"-13" slick tyre (overall diameter × width) in the rear on a 13"×18" rim, with a Goodyear 20.0"×9.2"-13" slick tyre in the front on a 13×10" rim. Slick tyres were introduced to Formula One by Firestone at the 1971 Spanish Grand Prix. During the 1960s, Dunlop introduced improved nylon casings, reduced aspect ratio, significantly increased tyre width, and the use of synthetic rubber. In 1958, Dunlop introduced its R5 racing tyre, replacing the cotton fabric of the earlier R1 to R4 tyres with nylon fabric, allowing for a reported 12 lb reduction in tyre weight. Both the latter - and successively the former - situations occurred at the 2021 Belgian Grand Prix.ĭuring the 1950s and 1960s, Formula One tyres were supplied by Dunlop, Englebert, Firestone, Continental and Goodyear. The race is either then stopped permanently or suspended for up to a 3 hour period until the cars can race safely again. ![]() In very wet races, such as the 2011 Canadian Grand Prix, the tyres are unable to provide a safe race due to the amount of water, and so the race can be red flagged. In extremely wet weather, such as that seen in the 2007 European Grand Prix, the F1 cars are unable to keep up with the safety car in deep standing water due to the risk of aquaplaning. The purpose of the tyre determines the compound of the rubber to be used. Whereas the latter has a useful life of up to 80,000 km (50,000 miles), the tyres used in Formula One are built to last less than one race distance. The tyres have undergone major changes throughout the history of Formula One with different manufacturers and specifications used in the sport.įormula One tyres bear only a superficial resemblance to a normal road tyre. The 2023 Pirelli tyres include (from left to right) the three slicks – called the hards, mediums, and softs – intermediates, and full wets.įormula One tyres play a significant role in the performance of a Formula One car.
