Tire pressure - down low and up high
So... was riding this past weekend, and as a part of my normal ritual adjusted the tire pressure to spec before heading out... and then watched as the PSI climbed as I rode up to altitude to get the hell out of the heat.
...and I wondered, what do other folks do in terms of tire pressure when heading from town (around 5400') up to altitude? Do you set it to spec and let the pressure climb? Do you set it a couple of PSI low to split the difference?
I've been riding for a long time, but dumbass that I am, I haven't really put too much thought into this before.
So... what say you, Denver Biker Hivemind?
Edit - so, did a bit more research, and found out that even just normal riding can increase tire pressure by 10%, so between that and altitude, the 7-8psi increase I saw wasn't really that much. Anyhow, appreciate the answers... which caused me to do a bit more detective work.
Regardless, thanks for the thoughts below...
