Siata - Siata 208S
The Siata 208S (Spider) was a lightweight sportscar with alloy bodywork designed by Michelotti and built by the coachbuilding company of Rocco Motto, available from 1952. It used the all alloy V8 2 litre Fiat "Otto Vu" engine, and was capable of speeds over 120mph. These were expensive cars and not many were made. There was also the enclosed coupe version Berlinetta called the Siata 208CS which were had bodies by Farina or later Balbo. Production of Siatas 208S and 208CS continued to 1955.
Tyre size for the Siata 208S and 208CS is the millimetric 165R400, of which Blockley produces the perfect high speed rated steel belt example, with correct diameter. See full details of this tyre at the link below:
