You know I used to put Armor-all on my tires (I don't that spelling is right either /w3tcompact/icons/crazy.gif), until my brother pointed out that the stuff attracts dirt, and turns the tires brown. He was using some clear stuff from turtle-wax (Clear Guard? not sure...).
However, these days I use some stuff called "No Touch" on the tires. Way easy! Spray it on, and walk away. Well, not quite; use a towel (or whatever) to wipe the no touch off the rims, then walk away. When the stuff dries, tires will be shiny & clean (with no residue).
