I did my test ride up the Burnley Rd and back. There are some patches of smooth tarmac along there but an awful lot of rough chip-and-seal.I put 6.5 bar (94 psi) in the rear and 6.0 bar (87 psi) in the front. I will do a test ride now and see how I get on with those pressures.
The tyres were rolling nicely on the smooth surface but I really was not enjoying the rougher stuff at those pressures!
I stopped at Cornholme and let out some pressure... Pft Pft Pft Pft at the front, and the same at the rear. The tyres still rolled pretty well, but the vibration due to the poor road surface was much reduced. Let's say from rather horrid to slightly irritating.
On the faster return leg I was still feeling a bit too much vibration so I stopped again and gave the front valve another couple of quick dabs. I rode on and was happy with those pressures front and rear. Still high enough to roll well, and to avoid pinch flats on anything less than big hits; low enough to be comfortable enough for most road surfaces that I am likely to tackle.
The only pressure gauge that have is on my track pump so I will have to squeeze the tyres to get an idea of how hard they feel now, then let them down a little and pump them back up to read the pressures. I would guess around 5.25 bar front and 5.75 bar rear. I will do that now and report below...
Hmm... I had clearly let out more pressure than I thought! Front and rear were both at around 5 bar (~75 psi). I normally put a little more pressure in the rear tyre than the front but 5 bar seemed to be good for both so I will stick to that. It is certainly easy to remember and read off the gauge!
