The P34 was reasonably successful with the two cars taking a memorable 1–2 in the 1976 Swedish Grand Prix. The Tyrrell team also finished 3rd and 4th overall in the championship. The car was less successful in 1977 however and the idea was dropped. Reasons given were that although Goodyear had manufactured special tyres for the car, the tyre company had failed to match the development work on them compared to the normal sized tyres used by other teams. With all four front wheels steering the car, Tyrrell also found that the P34's complex four-wheel front suspension assembly added a lot of weight to the car.
