Design and Engineering: A Closer Look at the P34
The P34 wasn't just a car; it was a bold experiment in pushing the boundaries of Formula One design. Chief designer Derek Gardner crafted every aspect of this six-wheeled marvel to take advantage of F1's physics and regulations. To truly understand the P34, we need to dive into three key areas: its daring four-wheel front-end concept, the engineering hurdles it introduced, and the critical role of custom tires. While groundbreaking, this design also brought with it a host of challenges that required equally creative solutions.
The Concept: 4 Small Front Wheels
At the heart of the P34's design was a clever solution to a tricky aerodynamic issue. F1 regulations on wing width left traditional front tires exposed, creating drag. Gardner’s ingenious response? Replace the standard two front wheels with four smaller 10-inch wheels. This allowed all the front wheels to fit neatly behind the wing, reducing drag and improving airflow over the car's body.
The benefits of this setup became clear almost immediately. When the P34 debuted at the 1976 Spanish Grand Prix in Jarama, it qualified third, trailing only James Hunt's McLaren and Niki Lauda's Ferrari. Beyond cutting drag, the four small wheels delivered superior grip compared to the usual two-tire setup. This enhanced front-end grip and cornering ability were particularly advantageous on tracks like Anderstorp in Sweden, where the P34 secured its historic Grand Prix win.
Engineering Challenges and Solutions
Building a six-wheeled F1 car was no small feat. One of the biggest challenges was the steering system. Only the leading front wheels were directly linked to the steering column, while a bell crank mechanism was used to transfer inputs to the second axle. This ensured both sets of front wheels turned in unison but added mechanical complexity and increased the risk of failure.
The suspension design also had to accommodate the extra wheels, making it bulkier and heavier than a standard four-wheeled setup. While extensive testing helped manage this added complexity, it still led to handling quirks and reliability issues. Braking was another persistent challenge - the unique layout placed significant stress on the system, leading to retirements despite ongoing improvements.
Derek Gardner later admitted that the development of the custom mini tires was "almost non-existent" compared to Goodyear's standard F1 tires, which ultimately limited the car's potential.
The Role of Goodyear Tires

Tires were a critical component in making the P34 concept work. Goodyear played a pivotal role as the only manufacturer willing to produce the specialized 10-inch tires required for the car’s unique front end. These weren’t just shrunken versions of standard F1 tires; they had to be engineered with new compounds and construction methods to handle the specific loads and heat cycles generated by the P34.
However, while Goodyear made strides with its regular F1 tire development during the 1976 and 1977 seasons, the custom tires for the P34 received little attention. The 1977 P34B, which featured a wider front track, inadvertently exposed the small wheels to airflow, negating the original design's aerodynamic advantage. This lack of tire development, combined with the car's inherent mechanical complexity, ultimately hindered its performance.
By 1978, Tyrrell abandoned the six-wheeled concept and returned to conventional designs. Even so, the P34 left a lasting mark on Formula One. Its inventive take on the regulations not only gave it a competitive edge during its time but also inspired other teams - like March, Ferrari, and Williams - to toy with six-wheeled designs in the years that followed, though these later experiments took a different approach.
The P34 remains a testament to the spirit of innovation in Formula One, a sport where bold ideas can redefine what's possible, even if only for a brief moment on the track.
