Aston Martin - Aston Martin 1.5 litre
Lionel Martin had been building cars for more than a decade when in 1921 the first "production" car was marketed, all of which were fitted with side valve Coventry-Simplex 1.5 litre engines. These cars were in production to 1925. When the Bamford and Martin company was taken over by A C Bertelli, the cars were fitted with a redesigned version of this 1 1/2 litre engine (now having overhead camshaft) starting with the first series in 1927 which continued through the Series 2 and series 3 which continued in production in to 1936.
Tyre sizes for the earlier Aston Martins were:
- For the Bamford and Martin cars tyre size was originally beaded edge type and size 710x90 . Blockley produces the best 710x90 tyres available anywhere, along with correct thick butyl inner tubes to suit.
- Tyre size for the 1 1/2 litre Bertelli Aston Martins was originally 450x21 for the first series of cars built between 1927 and 1932, and Blockley produces the perfect 4.50x21 tyre, which offers better handling than any other tyre available, with an authentic period correct tread pattern. See details of this tyre below:
-Tyre size for the Aston Martin Series 2 and Series 3 models was 5.25x18, which is a size no longer available, so the tyre size used for the past 80 or so years has been the 5.50x18 . Interestingly some Aston Martins left the factory with 19 inch front wheels, so having a 5.50x18 rear 5.00x19 front tyres is the best combination - both these tyre sizes having the same diameter.
