Take the pressure off
Lower tyre pressures can raise grip levels by increasing the tyre’s contact patch and allowing it to deform over debris rather than bounce off it. These benefits are true on dry roads as well, of course, but on a wet road surface, where grip is at a premium, reducing tyre pressure can pay additional dividends.
Lighter riders in particular can afford to run quite low pressures, perhaps as little as 80psi for a rider of around 65kg. The attendant benefits of improved comfort and increased grip should outweigh any disadvantages from greater rolling resistance, which is likely to be negligible. Tubeless tyres, such as the previously tested Schwalbe Ultremo ZX tubeless, can be run at lower pressures without fear of pinch flats.
