We were in Seattle, WA a few years ago & we were on a Parkway A pickup w/ a camper was ahead of us in the right lane & all of a sudden his left front tire came flying off. Went across the highway in front of us, we thought he was going to flip ove but he didn’t. Thank goodness it was early in the morning on a weekend or there would have been a lot of wrecks. Know a girl the same thing happened to.
