Sure. That's why cars like Bugatti (21" in rear!), Audi R8, all Ferraris and Lamborghinis, Corvette ZR1 and many others high performance cars use 19 and 20 inch rims. Just for looks, compromising performance.

Of course you can buy "regular" Corvette with 18 inch rims, but no ZR1. ZR1 is "good looking" model, for performance go with C6 Coupe on 18 inch wheels.

I did too. And that is why I say you have no idea what you are talking about. You right - big difference. 18 inch tires are "comfy" - or, to be precise, little more comfortable on potholes then 19 inch tires. Better ride? Sure. Better performance? In your dreams.

Either you didn't drive back to back M3 with 18 and 19 inch wheels, or you didn't pay any attention. There is a good reason why you cannot buy any Ferrari or Lamborghini on 18 inch wheels and it is not looks.

And I'm not saying, that 18 inch wheels cannot perform extremely well, but when you compare tires 265/40-18 to 265/35-19 there is no way car will handle better on tires with smaller rim, taller sides. Difference may be small, but always that difference will be for 19 inch tire advantage.

...Unless, of course, ride quality is your goal. In that case I suggest you to buy a Buick.
