I drove about 400 miles today in my 65, and after making a turn to go the last 14 miles to the house, it sounded as if i had a flat.
Ya' know that flub, flub, flub sound? So I pulled over to find that all 4 of my tires were inflated. I popped the hood to see if something came loose, and nothing. I looked at the brakes and they all seemed intact. The last thing I did before getting back in the car was to check the lug nuts. Sure enough, the left side driver's side wheel's nuts were loose. I had a flat on that tire a few weeks back, and the tire changer/flat fixer didn't torque the lug nuts. He just used his air gun. Well, I'm here to tell ya.....torque those suckers to at least 70-80 pounds, because they will loosen. It's a good thing I wasn't going 80 MPH in the middle lane of the San Antonio freeway like I was doing a few minutes earlier.
