Problems pumping up tyres!

I have an app for correct tyre pressure. It's admittedly a bit of an ask when daily weight fluctuations result in fractional values, but you have to be precise about these things. Stop after each sip from the bidon, re-calculate. Take bike and pump into the toilets at the cafe stop and adjust. That ineffably pleasing extra precision when cornering and a jolly good feeling all round of doing the right thing make the small bit of additional effort involved well worth doing it.

An app?? Bloody hell. My system:

1. Notice tyres a bit flat
   
2. Ride for 2 additional days
   
3. Pump the shit out of them.
   
   

repeat.

It looks like you have missed the point of this post. You may wish to submerge it in water and look for Germanic sarcasm.
