Are you implying that driving 70 + miles per hour in a modern car is unsafe? Or just with overinflated tires? I would never put my kids in danger unnecessarily. But when you are driving on a freeway trip of 14 hours plus and you are accomplishing it in one day and the speed limits are 75 miles per hour on the Interstate, you do what you have to do.

I had a blowout in my Chevy Avalanche pulling a U-Haul at 70 miles per hour and it was not a lot of fun. When I was a kid, my crazy stepdad had a front blowout going 70+ and almost killed us by slamming on the brakes.

So I am justifiably a little paranoid about blowouts.

Because of your "guru status" Wayne, I will indeed investigate the possibility of running at higher pressures, but I admit when I checked my pressures on a not so hot August day and saw an extra 10 PSI in my tires, I got a little concerned. I want neither a blowout nor a tire which needs replacement early because of undue wear on the middle section, which CAN and DOES happen in long periods of overinflation - I found that out with my Avalanche tires.
