The Tyrrell P34, commonly known as the "six-wheeler", was a Formula One (F1) race car designed by Derek Gardner, Tyrrell's chief designer. The car used four specially manufactured 10-inch diameter (254 mm) wheels and tyres at the front, with two ordinary-sized wheels at the back. Along with the Brabham BT46B "fancar" developed in 1978, the six-wheeled Tyrrell was one of the most radical entries ever to succeed in F1 competition and has been called the most recognisable design in the history of world motorsports.

The Tyrrell Racing Organisation was an auto racing team and Formula One constructor founded by Ken Tyrrell (1924–2001) which started racing in 1958 and started building its own cars in 1970. The team experienced its greatest success in the early 1970s, when it won three Drivers' Championships and one Constructors' Championship with Jackie Stewart. The team never reached such heights again, although it continued to win races through the 1970s and into the early 1980s, taking the final win for the Ford Cosworth DFV engine at the 1983 Detroit Grand Prix. The team was bought by British American Tobacco in 1997 and completed its final season as Tyrrell in the 1998 Formula One season. Tyrrell's legacy continues in Formula One as the Mercedes-AMG F1 team, who is Tyrrell's descendant through various sales and rebrandings via BAR, Honda, and Brawn GP.
