Armor All® - 4 oz. Spray Bottle Tire Foam Tire Dressing for Deep Black Look

This product works great because a) it's relatively cheap and b) gives a good shine without looking hideous Basically, it doesn't provide that ultra-greasy look you might get at a $50 detail operated by some homeless looking guy who applied a layer of grease to your tires. Instead, you get a new-tire looking effect that simply looks good all the time. Easy to apply- just spray on. However, make sure you try to spray on uniformly and don't put too much. But before you do that, if you're applying this while the car is in your garage or driveway, cut up some cardboard boxes and drive over them. This way, all the residual droplets wont stain your concrete. Let the liquid sit for the recommend amount of time, then go out and use a paper towel to dab, not scrub, away excess dirt and liquid. Make sure you do not leave any traces of liquid because if you do so, the next time you drive your car, centrifugal force will stream even small traces of excess liquid right off to your side panels.

It does make the tires shine and look nice, however it claims to last for weeks and it doesn't. Days at best, and any rain washes it right off. The trigger bottle is incredibly cheap. If you tilt it at all it won't spray, which is annoying because you have to kinda turn the bottle sideways to spray the lower part of the tire to coat everything evenly. When there's enough left for just a couple more applications it gets frustrating because it doesn't want to spray.
