These outer wheel bands where adapted with a covering of rubber riveted/secured on the outer contact surface. They where adapted from horse drawn carriages of the time. They where available in the 2 width fittings 55mm and 90mm. The French term was “bandages caoutchouc de 55/90mm” – rubber tires. Being solid they where sometimes cut for more grip and these altered as other covering materials became available.

The pneumatic tyre became a option in the mid 1930’s, the constrains of use being the number of paved roads in the countryside not the pneumatic tyre it self.

The pneumatic tyre was first patented in 1845 (Scottish inventor Robert William Thomson) But the first practical tyre was made in 1888 by John Boyd Dunlop (in Belfast), of a cross-ply based construction. His company later becoming the Dunlop tyre company. Much later on (1946) Michelin invented the first radial tyre in 1946 and revolutionised the tyre industry. Both Cross ply and radial tyres used the vulcanisation technology/process developed by Charles Goodyear from the USA. 3 company names we know today.

Interestingly the word Tire (american) has its origins from the French word Tirer (meaning to pull).

The first recorded cost for the pneumatic tyre option for the Energic motoculteurs C7 and D9 was an additional 1460Frs in 1935 (Roues a pneumatiques) Brand Dunlop.

I was lucky enough to find a very early tread pattern on a project I am working on.
