In your article from 16-Feb-2007 you state that “As for moisture, changes in humidity affect tire performance two ways. First, the density of humid air fluctuates more with temperature than that of dry air, so removing humidity can keep your tire pressure more consistent, especially when the temperature climbs over 100 degrees Fahrenheit. That may be a legitimate concern in Formula One racing, but it’s not much of an issue if you’re just tooling around town.”
Can you tell me what temperature a tire is when it is 90 degrees Fahrenheit… if the tire is being driven on a black top highway at 65mph? I am willing to bet that the friction alone will get the tire hotter than 100… much less adding in the blacktop or a possible under-inflated tire.
P.S. The green caps are sexy!
