Re: [ST] tyre pressures

["David W. Funk" <dwf@xxxxxxxxx>]

If you are going to play with tire pressure, you need to use an air pressure 
gauge. By that I mean while riding. After riding a section of road, say 10 
minutes or so if you started with warm tires, stop and measure the pressure 
as quickly as you can. You will be looking for a 10% to 20% pressure rise 
from cold. Just what pressure rise works best is the debate, but 10% - 20% 
is a good limit. For long distance I would aim for something close to 10%. 
For maximum traction, around 15%. A 20% rise is a fairly large amount.
But in all cases it is how the tire / pressure works for you. So far I have been 
satisfied with the recommended 36/42 psi.

wouldn't mess with lower pressures more than 3 PSI. To hot a tyre kills 
design life.
