Vauxhall - Vauxhall Wyvern
The Vauxhall Wyvern introduced in 1951 was an all new design, utilising a monocoque design of chassis. Initially it was fitted with the older Vauxhall 1442cc overhead valve long stroke engine, but when the RAC horsepower taxation calculation got changed (which was originally based on bore size only), Vauxhall built an almost square 1507cc engine which was installed a few months afterwards, during 1952. For 1955 the front of the Wyvern was changed, and yet again in 1957. Vauxhall Wyvern production went on to 1957.
Tyre size for Vauxhall Wyvern was 5.60x15 which is radial equivalent 155R15. Blockley produces this 155HR15 tyre size in both standard and whitewall versions. But many people like to fit the very slightly larger overall 165R15 tyre size. Blockley produces both these 155HR15 and slightly larger 165VR15 tyres - see full details of these 2 tyres at the links below:
