i would assume the only reason people do that is because the increased surface area of tire to road from the decreased pressure would only heat up the tire faster. but i dont think the raise in temp would not raise the tire pressure to optimum performance though. am i right???

I always add a little more than usual, and it depends on how cold it is. I usually don't ride when it's below 40 F out here, so i add 3 lbs more than usual if it's in the 40s.

I am curious as to why you add more?

Have a look at Charles' Law....

At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature (in kelvin) increases or decreases.

Cheers,
Pete
