The car handling in high cross winds has greatly improved with the pressure at 38 psi.

Your flat issues may have been from the inspections stickers inside the American Classics and not from tire pressure. I got four damaged tubes from those stickers until I became aware and replaced them. Quite a few with American Classic Radials have has the same issues. I went ahead and changed out the spare also, just in case.

I run mine at 35psig, no problems since.
