Four generations of tire knowledge. My great-grandfather started in the 20ties. He began as a shoemaker. Repairing shoes was similar to repairing rubber tires for a bicycle or t-ford. In the 1930s, he started trading in tires and oil. My grandfather sold his tire factory (by then) in the 70ties to Vredestein, and my father restarted wholesaling tires in 1988. TTI was founded. Since 2012 Gummistrada has run some of the best b2c websites. Gummistrada trades in car tires, motorcycle tires, quad tires, scooter tires, truck tires, wheels, and software for retail stores. The network of 4 generations is a vital asset for some fantastic opportunities we share with friends in the industry.
