Hey,
I think nothing is more gross looking than a typical "dressed" tire - most look like they've just had salad oil drizzled on them. I do think that careful application of a good product and then buffing can make them look new though, which I've always thought the goal should be.
But what do people think of this: "tires become discolored as a side effect of their built-in chemicals - the waxes and antioxidants that form a protective coating against airborne elements, according to Bill Vandewater, consumer products manager in sales engineering at Bridgestone/Firestone North American Tire. Aftermarket shiners can restore a tire's color, but they strip the tire of its original protestants. The result? Vandewater says that over time, cracks form in the rubber. As an alternative, he suggests using mild soap and water with a good brush on the tires."

Any advice on this? I figured a good product should replenish the anti-oxidant protection on tires, not strip it.
