The science behind the modern rubber formulas used by major tire manufactures today is both complex and interesting. The rubber itself contains and ingredient called Antiozonant
Antiozonant is an ingredient that helps to prevent the exterior rubber surface from cracking, checking, oxidizing, and deteriorating. The rubber is designed in such a way as to constantly work its way to the outside of the tire and as such, continually replenish the exterior surface with fresh antiozonant.
After the antiozonant works its way to the outside of the tire and is exposed to the ozone in the air, it turns brown
. The technical term for this effect is blooming
This is why you see a brown film on the surface your tires. You can wash your tires with soap or an all-purpose cleaner and remove this film, but in a few weeks, it's back. That's because the antiozonant continually works its way to the outside of the tires every time you drive your car.
Thus before applying a dressing you really need to do a thorough job of cleaning the outer surface of the tire to remove any spent antiozonants as well as any previously applied dressing and this will prepare the rubber to accept a fresh application of tire dressing. Meguiar's Tire Dressing Options

Second, the Sun is a major contributor to drying out and cracking anything, both the visible sun rays, (light), and the invisible sun rays emitted by the sun.
Besides the rays then theirs the heat created by the sun to the surface and the environment. The worst areas for drying and cracking are places were the tires are exposed the extreme sun for a majority of the year. For example out here in the desert where I live the sun pretty much deteriorates everything that's not covered up and protected. Goes with the territory.
