Austin - Austin 3 litre
The Austin 3 litre started becoming available in 1968, although a prototype had been shown earlier in 1967. This car was the replacement for the top end A110 Austin Westminster. Sales were not good and the standard version was withdrawn in 1969, leaving only the higher specification model. The reason for this could be that it looked no different to the 1800 Series front wheel drive Austin and Morris 1800's, only just bigger (and with rear wheel drive). And when it was made it was competing with cars such as the Rover P6 and Jaguars which were all now also part of British Leyland. The Austin 3 litre was discontinued in 1971.
Austin 3 litre tyre size was quoted as radial size DR70SR14 which is the same as the Blockley 185HR14 . Blockley also produces a whitewall tyre in this 185HR14 size.
