Tire Casing and Tire Pressure
Most of our previous data has been tested with World Tour riders who are using some of the fastest tires available. Tires with extremely supple casing are significantly more efficient at absorbing road vibrations so they are able to run higher pressures more efficiently. The lower quality casing, the lower the breakpoint pressure will be. The optimal pressure can be as much as 20% lower on a low quality casing vs the highest quality available.
