So this isn't really cheating – it's just a trick you have available with wide tyres. On the trails I then lower the pressure to “normal MTB” levels, which wouldn't be possible with narrow tyres without instant puncture guarantee. | |

| May 30, 2021 at 21:46 | comment | added | Ross Millikan | @Michael: Sometimes the comparison is at equal pressure with a misguided idea to remove one variable. I would argue (similarly to you) it should be "normal" pressure for the tire, whatever that is. It can be hard to define. | |
| May 30, 2021 at 19:56 | comment | added | Michael | One thing I’ve always wondered when comparing different widths: How do you choose the pressure for a fair comparison? I think the only fair comparison would be with equal “suspension travel” or equal comfort (i.e. shock/acceleration). | |

More generally tire width isn't as important as how the tire is made (if it is "supple"). FWIW he does claim that a well designed, supple, knobbly tire can roll almost as fast as a well made supple slick tire. renehersecycles.com/bq-tire-test-results | |
