Throughout the mid to late 20's the Austin 12/4 fitted a 475x21 tyre. The majority of vintage tyres near this size are now called 440/450X21 because this was a very popular Ford Model A tyre and late Ford Model T, as a result there is plenty of choice and some good value vintage Austin tyres in this size. Longstone vintage tyres presently would suggest that the Lucas tyre is as good a quality as the other vintage tyres in this size but the price is extremely good and they have a very vintage appearance.
Recommended Austin 12/4 21" tyres
Austin 12/4 21" tyres for a standard car as recommended by Longstone Tyres. We would recommend the 440/450x21 Lucas as the best tyre in this size and it is extremely good value.
Austin 12/4 20" tyres
Austin heavy 12's fitted 475/500x20. In this size the Dunlop is the best structured handling Austin tyre you can get but because it gives slightly lighter steering and a more period look the Firestone is often more popular for Austin heavy 12's.
Recommended Austin 12/4 20" tyres
Austin 12/4 20" tyres for a standard car as recommended by Longstone Tyres. We would recommend the 475/500x20 Firestone as the best tyre in this size for an Austin 12/4
Austin 12/4 19" tyres
Austin 12/4 19" tyres for a standard car as recommended by Longstone Tyres. We would recommend the 475/500x19 Michelin as the best tyre in this size for an Austin 12/4. However the Lucas tyre is extremely good value for its quality.

History of the Austin 12/4
The Austin 12/4 was introduced by the Austin Motor Company in 1921. It was the second of Herbert Austin's post World War I models and was in many ways a scaled-down version of the 20
Initially the Austin 12/4 was available as a Tourer, by 1922 three body styles were offered, these being the four-seat tourer, the two/four-seater (both at £550) and the coupé at £675.
Austin's 12/4 enjoyed success throughout the vintage era with annual sales peaking at 14,000 in 1927.
While the mechanical specification of the Austin 12/4 changed little (the engine increased from 1661 cc to 1861 cc in 1926), many body styles were offered with saloons becoming more popular as the twenties drew to a close.
The 12 continued in the Austin catalogue until 1935 and as a Taxi option until 1939. The last cars were produced for the War Department in 1940.
During the early thirties, the car began to become known as the "Heavy 12", to distinguish it from the other, newer, 12HP cars in the Austin catalogue ("Light Austin 12/4", Austin 12/6 etc) and received some updating. The Austin 12's artillery style wheels were replaced by wire spoked ones in 1933 and coil ignition replaced the magneto in 1935. The gearbox got synchromesh on its top two ratios in 1934. The body range was steadily simplified with the last of the fabric covered versions in 1931 and no open Austin 12's after 1934.
After the war the Austin 12 name returned to the Austin catalogue for a couple of years until the arrival in 1947 of the Austin A40 Dorset and Devon saloons.
Today, the Austin 12/4 is remembered as being virtually unburstable and is well catered for by the Vintage Austin Register in the UK and various other clubs in other parts of the world.
