First and foremost:
Goodyear= Polyglas (Speedway WideTreads,etc)
As for ride, they came out on the cars that we love. That is also why they had rubber bushings and other things to help with the ride. Tires are definately part of the suspension package. Yes, there are some radials that are being made with redstripe/whitestripe/bluestripe. There are also radials that are in RWL. Makes sense to go into a market trying to pretend to be something you are not (New Tire trying to pretend that you are old?)
Many guys have no problem taking their bias ply stuff out and running down the highway with it. And they bite extremely well at the drag strip!!!
