It wasn’t too long ago that the only pressure you were supposed to inflate your tyres to was the maximum recommended: normally 120 psi or more. You were given this advice by any experienced cyclist and this was often accompanied by dire warnings of catastrophic pinch flats if you ran anything lower, and of course that old ‘fact’ that the higher the tyre pressure the faster the bike.

This belief also coincided with a time when 23mm was as wide as most ‘proper’ cyclists would go and a 25mm was seen as a boat anchor more suited to commuting or touring use.
