Alvis - Alvis 4.3
The 4.3 Alvis was built in the same year as the Speed 25, in 1936. Enlarged from 83mm to a 92mm bore size, the engine was almost 4.4 litres capacity (4387cc) so a mystery is why this model was not called the Alvis 4.4 litre! This larger capacity engine was put in a modified Speed 25 chassis, to provide a genuine 100 mph car, which was fitted with independent front suspension.
Alvis 4.3 tyre size from the factory was 5.50x19, and Blockley produce the perfect 550/600x19 tyre for the 4.3 Alvis. Our Blockley tyre will transform the handling and ride qualities, and is the best tyre you can buy. See full details of the Alvis 4.3 litre 550/600x19 tyre at the link below:
