I expect to run about 45psi, but I know others go lower and it makes such a big difference.įor me 40mm is about the magic number for speed/grip/tolerable comfort. Put simply do not attempt the Dirty Reiver with tubes unless you’re rims just don’t work tubeless. I’ve been tubeless for years now on MTB and on gravel and I can’t remember the last time I had to put a tube in. Tubeless means lower pressures and more compliance for comfort, self sealing with sealant for most flats and lighter rotational weight. I have learnt in the last couple of years to mix it up with lower pressures and the right tyre and I’m never going back to tubes. To avoid punctures I used to run about 70psi with tubes but I’m sure the extra muscle fatigue from the solid tyres outweighed the speed advantages. I have found a few that survive and should be reliabe for the riding like the Reiver route involves.
A lot of tyres I use seem to rip or spray sealant too easily and while I ride fast I’m not that heavy compared to some at 75kg.
