Those ultra-low profile tires do two things: they provide enough room for the huge brake discs without being cartoonishly large, and their sidewalls are so small that the tires flex very little under side loads, giving better handling.

Low profile tires are done for styling reasons only. They claim that it's for sidewall flex or whatever. If this was really true, then real race cars would do it too. Look at a Formula 1 race car, arguably the highest performing wheeled vehicles on the planet. They don't have low profile tires. Same for NASCAR vehicles. No low profile there, either.

That observation has occurred to me also and with extreme bemusement.

I especially hate to see a 4WD with low profile tires.
