Austin - Austin 20

The Austin 20 was Austins car to appear after World War 1. The Austin company had built so many differing models, and the range needed to be rationalised in order to have an efficient production line. The Austin 20 was a 4 cylinder 3.6 litre, powerful and fast good quality car which offered an alternative choice for a customer looking at something like a Rolls 20. However the Austin 20 was possibly the wrong choice in the single model policy, and by 1921 the Austin 20 needed to be augmented with a 12hp and shortly after 7hp models model. From 1932 the Austin 20 became a six cylinder 3.4 litre, still with side valve engine. The Austin 20 was produced until 1938, when a larger bore version took over.

Tyre size for the Austin 20 :

- The original Austin 20 models built between 1916 and 1928 had tyre size 820x120. Blockley make the best beaded edge tyres. If your wheels have been changed to a later type, Blockley will also have the tyre size to suit.

- The Austin 20 built between 1929 and 1931 was fitted with 31x5.25 tyres which is the same as 5.25x21 tyre size, which Blockley produces.

- The six cylinder Austin 20 built from 1932 to 1938 had original tyre size 600x18. We would recommend the Blockley 600/650x18 tyre which size has the perfect dimension.
