I did not know this until the other day when I read it on the bmwmoa site. Tire inflation recommendations [ on Beemers anyway ] is set at 68 degrees F. For every 10 degrees above or below that in ambient temperature, add or substract 1# to the tires. So, I've been underinflating my two Beemers tires since the ambient temp in my garage has hovered at 95-98 degrees here in the desert. Which means for me, instead of 38/42 on the GS cold, I should have been setting them at 41/45 pressure. On the K bike, instead of 36/42 they should have been set at 39/45 cold before riding off for the day. I'm not sure how many actually know this or if I'm the only one here who was a duh on this, but thought it might have value to some members who were oblivious as I was until recently.
