I have used all sorts of time products in the past. I have just found one I really like. It is G ultimate tire shine. It is environmentally save. It does not leave marks in my asphalt drive way when I spray it on. It is not high gloss. It gives a clean look without dust sticking all over them. I drive dirt roads often, and all the other products I have used just stick dust to the tires and they look like crap after one dirt road trip. I can actually rinse the dust off of this stuff with a hose and they look new again. It also works for my running boards. It gives them a dark black look but they are not slippery. One application has lasted at least 2 weeks. I suggest giving it a try!
