Energic motoculteurs with tyres.
Initially, the Energic Motoculteur range was only available with metal wheels, with metal outer wheel bands available as an option for ease of movement on medium to hard surfaces. The wheel bands were originally available in 2 widths 55mm and 90mm.
Outer wheel rims, different widths.
Later with ridges to increase grip on smooth surfaces.
These outer wheel bands were adapted with a covering of rubber riveted/secured on the outer contact surface. They were adapted from horse-drawn carriages of the time. They were available in the 2 width fittings 55mm and 90mm. The French term was “bandages caoutchouc de 55/90mm” – rubber tires. Being solid they were sometimes cut for more grip and these altered as other covering materials became available.
Bandages caoutchouc de 55mm – rubbered rims.
Artisanal adaption of the outer rim with rubber/tread.
The pneumatic tyre became an option in the mid-1930s, the constraints of use being the number of paved roads in the countryside, not the pneumatic tyre itself.
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 in 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 pneumatics) Brand Dunlop.
I was lucky enough to find a very early tread pattern on a project I am working on.
Here is another project Bour with those old Dunlop originals.
The following tyre treads were originally used:
