Temperature: with both solid and pneumatic tires, rolling resistance has been found to decrease as temperature increases (within a range of temperatures: i.e. there is an upper limit to this effect) [59] [60] For a rise in temperature from 30 °C to 70 °C the rolling resistance decreased by 20-25%. [61]
ISO 5775. ISO 5775 is an international standard for labeling the size of bicycle tires and rims. The system used was originally developed by the European Tyre and Rim Technical Organisation (ETRTO). It is designed to make tire sizing consistent and clear. It replaces overlapping informal systems that ambiguously distinguished between sizes.
From a mechanical viewpoint, up to 99% of the mechanical energy delivered by the rider into the pedals is transmitted to the wheels (clean, lubricated new chain at 400 W), although the use of gearing mechanisms reduces this by 1–7% (clean, well-lubricated derailleurs and a straight chainline), 4–12% (chain with 3-speed hubs), or 10–20% (shaft drive with 3-speed hubs).
The word tire is a short form of attire, from the idea that a wheel with a tire is a dressed wheel. [3] [4] Tyre is the oldest spelling, [5] and both tyre and tire were used during the 15th and 16th centuries. During the 17th and 18th centuries, tire became more common in print.
