In all seriousness, I've never been able to tell any difference between the old polyglass tires and today's tires. Right up to its demise in 2001, I had polyglass Goodyears on my 70 Challenger and radials on my Thunderbird and Mustang, and they all handled pretty much the same, tire-wise. Of course, I do pretty conservative driving and it doesn't snow or even rain here much, so maybe that's a factor.
