Osca MT4 Classic Tyres
- The Osca MT4 fitted 5.00 - 15 Classic Tyres.
- We recommend fitting the 5.00 x 15 R5 Dunlop Racing For the race track.
- It is worth pointing out that (unlike the 16” R5) 15” Dunlop Racing R5 tyres are not road legal.
- We would suggest the best road tyre for an Osca MT4 would be the 155 HR 15 PIRELLI CINTURATO CA67.
- Osca MT4 cars fitted Borrani wire wheels; wire wheels need innertubes in order to function effectively.
- The Osca MT4 innertube we offer for this size is the Michelin 15E.

History of the Osca MT4
Osca MT4 Spyder
The MT4 was the first automobile constructed by Osca. The name MT4 stands for Maserati Tipo 4 Cilindri (Maserati type 4 Cylinders) referring to the MT4's 1,092cc 4 cylinder engine that was constructed with an in house designed engine block. The bodywork was constructed as a two-seater Barchetta, which refers to a Bodystyle of an open-top two-seater sports car. The engine was modified to an even larger 1,342cc capacity in 1949 and in 1950, a new Double-Overhead camshaft was added to the engine, further raising the power to 99hp at 6,300 rpm and again this increased to 108hp at 6,200 rpm with an engine size increase to 1453cc in 1953. In 1955 the engine was upgraded to an all-new Tipo 372 DS twin spark engine with a capacity of 1491cc which produced 118 hp at 6,300 rpm. This engine was implemented in the MT4 TN (Tipo Nuovo) the same year and received the new name FS 372, only 5 were constructed.
The Osca Mt4 was first raced in 1948 at the Pescara Circuit and the Grand Prix of Naples, where Luigi Villoresi claimed a victory. The 1954 12 Hours of Sebring was won by Stirling Moss and Bill Lloyd in an OSCA MT4 with the Briggs Cunningham team. Sir Stirling Moss continued racing his own MT4 across the globe until his retirement in 2011.
