Iso - Iso Rivolta IR 300
The Iso Rivolta IR 300 was the first foray of Renzo Rivolta into full size automobile manufacture, let alone a Gran Turismo. It was a project of Rivolta with the help of Giotto Bizzarini, and tasteful bodywork design by Guigaro. What made it very unusual for an Italian car was that under the bonnet was a small block 327 (5350 cc) Chevrolet. The Iso Rivolta IR300 was available from 1963, and for 1964 an option Rivolta IR340 was also offered with higher performance. Production of both models continued until 1970.
Iso Rivolta IR300 and Rivolta IR340 tyre size was originally 185R15 , and Blockley produces a superb high speed rated 185VR15 tyre. A non standard alternative tyre size is the same diameter but wider 205/70VR15, a size which Blockley also produces with a W speed rate. See details of both these tyre sizes below:
