Evidently, cold tyre pressure is a lot more reliable a means to keep track of.
Have noted the tyre pressure to often change between 2-5psi from cold to warm readings. It could be more, or rarely, even less. So the 32 you talk about - if it is warm, it may anyway be about 29 cold.
Thanks Poitive. I fill 32 when warm and also the suspension is not compromised at this pressure. Feels comfortable in city.
