[DeTomaso] Tires, Tire Life, and Nitrogen

[Tomas Gunnarsson]

Their explanation mentions humidity but for some odd reason they explain it as if ambient humidity would make a difference. What would matter is the humidity where the tires were filled IMO which is not neccessarily where they're used. I do understand that the amount of water in the tire matters but for street driving it sounds plain silly.
