Riley - Riley One-Point-Five.
The Riley 1.5 became available at the end of 1957, some 7 months after the similar looking Wolseley 1500, as part of the BMC range. The Riley was based on the Morris Minor chassis using its rack and pinion suspension and floor pan, and using the larger 1489cc BMC B engine. This was mated to a gearbox from the MG Magnette. The Riley 1.5 had the more powerful version of the 1500cc BMC engine fitted with twin SU carburettors producing 65bhp as standard. Consequently as a result of the better performance this Riley was fitted with much larger Girling brakes. The capacity of the Riley One-Point-Five never changed but in 1962 the engine did get some upgrades with a more robust crankshaft that had larger journal sizes, and these Rileys were often raced and Rallied in period. Although virtually identical to the Wolseley 1500, the Riley sold less units because of its higher price tag. Production carried on to 1965.
Riley One Point Five tyre size was 5.00x14 originally. The radial tyre equivalent to this size is 145R14 . Blockley produce a steel belt construction good speed rated example, with period correct tread pattern and correct diameter 145R14 - see full details below of why the Blockley 145R14 is the best option for the Riley One-Point-Five at the link below:
