Thanks for your reply. I've been in the auto hobby since 1971 and am familiar with, well just say, things. As well as Auto Forums, although I don't have many posts on this forum the others I belong to I have thousands and we always try to help "newbees" as well as "oldbees" out... No offense taken by your reply as I'm sure you didn't mean it to sound offensive.
The tire info I provided was straight off the door jamb factory sticker as well as matched the tires presently on the car, which my Father-in-law (Passed in 2018) had installed after the original ones needed it back in 3/2015. My wife (departed 6/21/2020) received his car as part of his estate. Now it's all mine, with a whopping 54,000 miles.
I understand rubber compounds which is one reason I'll never buy another set of Michelins, too hard dry rot before the tread is worn. Anyhow I'm going with a set of tires that I'll keep to myself to prevent further discussion on my question.
Time that God grants us is precious, priceless and too short for BS.
