The Sidecar Triple Duty crossply is quite an unusual tyre. Offered in a motorcycle size of 350-19, it was intended for fitment as a universal tyre to motorcycles and sidecar combos. This is why the tyre has a square-shoulder appearance, because it isn’t intended as a tyre to be leant over in corners like a standard bike tyre. 

As well as use with sidecars, this tyre can also be used for some of the light cars popular before the war, like the Austin 7 and Morris Minor.

This 350-19 Avon Sidecar Triple Duty crossply tyre is ideal for the following: Austin 7 (1926 to 1935), Morris Minor 8hp (1932-33), Frazer-Nash Fast Tourer, Super Sports, Boulogne, Interceptor, Falcon and Ulster, Humber 9/20, Lagonda 12/24, Morris Cowley and Oxford (1925).

This is a tube type crossply car / sidecar tyre
