Is a higher tyre pressure faster? Is a lower pressure more comfortable? Emma conducts an experiment to determine the fastest tyre pressure on a rough road surface. She tested all the way from 119 psi (8.2 bar) to 29 psi (2 bar), the results were surprising!

In a lab environment, a higher tyre pressure shows decreased rolling resistance, but this is a totally different matter out on the road. Emma admits in hindsight that she may have made some changes to the experiment to make the results a little more reliable. However, the data still highlights a very interesting trend and definitely suggests that the old-school beliefs about tyre pressure may be outdated. We hope this might inspire you to conduct your own little experiment. If you do, let us know how it goes and what data you discover!
