Hmmm....I see.....  Are the first 3 - 5 also on tarmac?  Do you carry a small tire pump? Seems the only thing to do is let some air out when you hit the woods, then pause for a break when you reach the asphalt again and pump 'em back up.  I have a pretty good little pump made by Topeak, and just a few puffs is all it takes to get the tires nice and firm.  Like the pit crew at a NASCAR race, I can get the tires prepped speedy-quick.

So, if I call you how long before you are track side, Mr. Pit Crew?? 
Actually, we have the CO2 cannisters that you puncture as our emergency "air".  Fits under the saddle, never had to use them yet.  I expect that we will find a range of pressures that work with different types of rides and with the Karma tires.
This last ride was very little asphalt, so 40 (or less) would have been a good selection.
One of the other rides was 5 miles back road asphalt, 7 miles packed jeep trail gravel, and then 5-6 miles on asphalt back to the car, and that's probably still a 50-60 psi ride (for me, maybe less for Lynn).


All this discussion has me curious.  I need to go back over and take a picture of the tree root obstacle course.
