Update, yesterday I am driving home from work, and a tire goes flat . Crazy sound, but surprisingly easy to steer. I pull off into a lot, change out the tire , and drive home. So today I am having all new Hancook h724 185/75/14 installed. $250 out the door includes their lifetime rotation and tire protection. Thanks for all your help. p.s. funny my spare, has a 185/75/14 on it. I bought it (used) a few years ago and never bothered to look at it.
