I use a product made by Zep called "zeprenew". It is an old-fashioned rubber dressing somewhat similar to RuGlyde. I bought several gallons years ago when I owned a service station. (Anybody old enough to remember those?) I don't think they make it anymore. Point is, it's a natural product, primarily glycerin. No silicone. You apply it to a clean tire and let it soak in overnight. The next morning, the tire has is completely dry and has a soft, low-gloss sheen just like a new tire. That's the look that I like. There are non-silicone tire dressings out there, you just have to look for them. I ran across a professional detailers' blog that had a lot of info on this, might be of some help with the magic of Google.
