tire pressure question

[l3uddha]

I probably should have asked this a while ago:

I checked in my garage this morning on a cold tire and read 30psi. I couldnt find my pump so I went to the gas station to fill up. when I checked it after about 10 minutes of riding it was right back up at 33psi.

is the recommended 33f/36r on the stock tires checked on warm or cold tires?

yup yup on cold .. if you check it after riding your tires are warm ... warm (hot) expands cool (cold )  extracts .. thats why if its like 80 out and you have 30 psi in the tires.. and it gets down to 40 that night .. your going to have like a 5 -8 psi drop .. you lose so many PSI for so many degrees of change in weather ...... if you can make out what i just said

thanks again!
