Later in the tests, we lowered the tire pressure on tarmac (also testing 2.5 bar and 1.5 bar). All tests were repeated multiple times on the same section – riding in both ways, like before, to subtract aerodynamic drag and determine the rolling resistance.
There are a few things to note from the results. For example, riding at 25 km/h with 1.5 bar required 12 more watts of power (in total) compared to 3.5 bar tire pressure.
