You are correct that wheels that attempt to pump air either toward or more likely away from the brakes have been around for a while. The fourth generation Corvette from 1985 had such wheels.

US20140191565A1 is only an application. It may or may not ever become a patent. Indeed, checking in the US Public Pair, I found that it's current status is "Abandoned -- Failure to Respond to an Office Action" as of 10-14-2014. The patent received a non-final rejection on 04-03-2014. Non-final rejections are pretty common so the prior art cited by the examiner must have been strong enough to convince the applicant to abandon the application.
I would like to point out that just because there are examples of similar products doesn't necessarily mean new inventions aren't possible. Many times the patent would be for a refinement on an existing product. The patent therefore would only cover the refinement and not the existing products.
