Red line radial versus bias ply

To remove the gray from your tires (as well as some stains from your white/red stripe, RWL) you can use a little lacquer thinner on a rag and sparingly wipe the tires down. It will bring them back to black in no time and does not leave a shine. It is the A-All that it graying up on the tires. Just remove it and start over.

After you wipe them down with a little lacquer thinner to get them clean, do you put anything on the tire, or just leave them a natural flat black rubber? Does Bleach-White work for removing the "gray" film, or will that cause the film to reappear?

Strange, but I found that the tires look fine over the winter, then the first time I drive the car in the Spring, all 4 tires have the gray film (I use Formula 2000, satin). Must be the heat generated in the tires, after driving a few miles, that brings the product (Armor All, etc.,) up to the top?
