Tyre Diameter: | Sunbeam Imp Sport and Stiletto 1966 to 1976

Sunbeam's badge engineered versions of the Imp were possibly the best of the bunch. Standard tyre fitment was a radial 155SR12.

The Rootes Group's small car competitior to the Mini came in many flavours over the years, but the Imp Sport had the hottest engine, and best handling. The Stiletto added to this by combining the Sport's engine with the Californian's jazzy coupe body, and some suspension changes.
