Thanks Sandy, I'm going to pass this info on to all my family and friends. I'll be checking my tires also. I bought my car just last March with expensive tires already on it. And two went flat in the past year. So I'm curious to know their dates, plus the dates of the two new tires I purchased. (Ok, I won't be able to find out the dates of the two that went flat, lol, but the dates of the other two originals might give me a clue).
Maybe this will explain why I never had trouble with cheap tires, they probably circulate faster than the expensive ones and are probably newer. Just a theory.
