Both the Cresta PC and Viscount came as standard with 590-14 crossply tyres, with the option of 700-14. The 590-14 crossply can be replaced with a 165R14 radial tyre, and the 700-14 with a 185R14 radial tyre.
The PC was the last top of the range model with the Cresta name, as the Viscount variant took the mantle in 1966. Luxury with big six engines and automatic gearboxes.
