said the heck with it and went to go take a cruise in the Mustang just a bit ago. I get in, low tire light is on. I start to think, naw, just off a little, temp changes sort of thing. Get about a half mile, paranoia kicks in and I pull in a parking lot. Sure enough, right rear is looooow. So I take it back home. Put air in it, as I am, I am checking the tire, sure enough, nail in it. Guess its off to the tire shop tomorrow.
