Sorry you didn't steal my thunder because we were talking about two different things. Handling is also impaired when you use the next bigger tire up even though it my fit. I also never had a harsher ride on a bias ply tire. What I have noticed is today's bias ply don't last as long as they once did. But good looking out for info that he may not have been aware.
