But that's a vague way of doijg things especially when tyres vary so much in many way ie; a Hyper is a world away from an M+ as slug from a greyhound.
To get the best from any tyre involves a lot more than readingnthe sidewall and pumping it up to that pressure,it's reason so many people are still stuck in the narrow high pressure = fast/wide low pressure = slow belief.
I think when I pumped up 26 x 1.75" Paselas on a tandem I just went for it, with no reference to what was written on the side of the tyre, got them so they felt right, then found on checking that they were at or about the max. Much lower than that and the tandem felt bouncy, which I don't like.
It was my impression that bike tyres are generally designed for the weight of one rider and a solo bike and putting the weight of two people on two tyres is going to require a significantly higher pressure than you can get away with if you only have one rider. And you are going to be nudging max as stated on the tyre.
You can also easily get close to the max load. Supremes in 1.6" variant have a max load of 100kg each. A tandem can weigh over 23kg, baggage can weigh 10kg say, which leaves only 167kg capacity for the riders. Most male / female combos would come in below that but some would exceed it.
For mixed use these Duremes look worth considering. https://www.sjscycles.co.uk/tyres/schwa ... nch-50559/
