Rolls Royce has Concealed Wheels

Justin Bieber recently had his Rolls-Royce Wraith - which begins retailing at $330K - fully transformed into something that looks like it is from outer space. This is what the Rolls Royce Wraith looked like before it was customized.


This is the customized Rolls Roys Wraith Justin Bieber had done. I think it's butt-ugly.
But what I'm curious about is... the concealed wheels. I've never seen any vehicle ever in my life with concealed wheels. It seems like f it was an ok thing to do, wouldn't car manufacturers have done it already? Won't tires overheat all covered up like that? I may be all wet but dang... I want to be able to SEE my tires.
