I use Meguiars Hot Shine Aerosol Spray because it has an adjustable spray pattern for low profile tires and tall sidewalls also such as pickups and sport utility's usually have.Pepperman's got some pretty good stuff in the picture he posted/ (meg's NXT) that works great also.I don't use too much because my car is white and most tire dressings like to "sling" onto wheel openings,lower body and sides of the rear bumper.I guess it's all trial and error like with anything else,because my local auto zone has almost half of an aisle devoted just to rubber and tire care.not too long ago you had armor all and STP son-of-a-gun! Now EVERYBODY makes something for rubber.For that extra touch on your car,the next time you wash it clean your wheelwells out good with a little Simple Green or equivilent all-purpose cleaner.after you rinse them out,let them dry a bit while you wipe down your car;after that spray a little NO TOUCH tire foam in your wells and they will not only look great but this will also make your wheels stand out and enhance the appearance of the whole vehicle.
