Wouldn't it be a difficult task (obviously was in your case) to locate a tire with cold tears~?~
Reason I ask is simple enough...if a cold tire is used and cold tears are shown on the tire, would the hot tears replace them after a couple laps...seems to me the only time you would see cold tears is if an accident occurred early on or some sort of malfunction that would keep the tire from warming up.
Could/would an extremely cold road do the same, even after miles of use~?~
