Sorry by simplifying. Hysteresis is the correct term. There are also some other effects that effect the roll resistance. It has a lot to do with the tire construction itself and the rubber used. We made some prototype tires reducing the roll resistance to a minimum. No more Steel…half the weight, 85 PSI rated, special rubber. They will not be cheap but they roll like a ninja. We just made the decision to produce them.
A lot of the cheap tires from China use funky plastics instead of rubber. Usually these are a bit more glossy just like the image shows. They even copied our Trampa Treads Tire down to the detail. Quality is so shocking…
Anyway: Try these 6" tires and see how they perform. If they perform, great! Hubs won’t fit skate trucks.
Would you like these? 125mm Urethane on Trampa wheels?
