Time to sitback, make a brew and get your inner bike nerd on!
Comparing the actual speed effect of running wider tyres at lower pressure compared to narrower ones at higher pressures is actually really hard to do.

Check out this podcast from CyclingTips and prepare to forget everything you ever thought you knew about what makes a fast tyre!
