You might want to consider using Nitrogen in your tires, its not affected as much by heat up and cool down like air is. I have been using it for over a year now and my tire pressures don't fluctuate at all. Nitrogen molecules are bigger and denser then air molecules so they also don't seep thru the rubber causing low tire pressures and rubber fatige (small cracks).
Plus I read somewere that it makes your bike faster due to it being lighter then air.
U know like the color Black.
