The earliest of these cars are nearly a century old, so it would be no surprise to find them on non-standard wheels and tyres. As a result, this is a guide only to standard fitments when new. Even then, not all the cars would have had standard tyres, and records can sometimes be contradictory. Please contact us if you would like to discuss fitments.

6C 1500 - In 1927, the standard tyre for the Normale models was a 29x5 crossply tyre (equivalent to a 500-19). In 1928 this changed to a 30x5.25 (equivalent to a 525-20). In 1929 the standard was a 28x4.95 (again equivalent to a 500-19). The sportier models (Sport and Super Sport) were fitted with a 27x4.75 tyre (equivalent to a 475-18).

6C 1750 - This model was built in more versions and by a greater variety of coachbuilders, so there is more variation in tyre fitment. As a general guide, cars supplied to the UK (in all versions) in 1929-31 had 27x4.75 (equivalent to 475-18) tyres. In 1932 things were a little less standard, some cars had 18-inch wheels, fitted with either 525-18, or 550-18; and some had 19-inch wheels with 450-19 or 525-19 tyres. From 1932 to the end of production it's a bit simpler - the majority of cars were fitted with 28x5.25 (525-18) tyres.

6C 1900 - The last development of the 1500 model. Available as a Gran Sport only, and only made in 1933. Its standard tyre was a 28x5.25.
