Worst thing about big wheels is the ride noise. Every time I've driven something with low-profile tyres it has had loads of rumble on the road, and given the most pimped-out wheels are often on the most luxurious cars, that must have their design engineers cringing.

Yes, and imagine how bad a car rides where not effort was made to handle those tires? Folks over here love to put them on Suburbans, Tahoe, Escalades - must ride like a dump truck (edit - 'tipper lorry', right?)!

What people also don't realize is that the big wheels will increase your braking distance. Not too too much, but if you need to stop in 50 feet for a semi up ahead and you stop in 54, well.......

How do they affect stopping distance because of the short, stiff sidewall?
I picture a "normal" tire, say a 75 or 70 series having some give as it scrapes over high and low spots allowing it to maintain grip; I picture the narrow sidewall wheel acting more like hard plastic as the pavement under goes up down and sideways, and not maintaining contact with the road.
Are there any studies?

My opinion (unencumbered by facts) is that these large wheels have much greater rotational inertia, hindering braking.

If one compares those Yank tanks to the period British and European iron, one can see the appeal. They were more expensive, but offered a lot of bang for the buck (or pre-decimalized pound back when it had value) compared to finicky European machinery. I am sure the American cars were also more durable...I know the Wehrmacht when conscripting cars into service loved to get American cars, due to durability.
I am sure driving something like a Zephyr or Airflow in 1937 Europe was even more of a shock to the passerby than in NA, too. Must have been an interesting time.

My E55 has 18"s - not so huge anymore, but with the low profile (and very expensive) tires, ride quality suffers, especially with the stiff tuned suspension. On smooth roads it is great, but I find myself dodging every bump and utility cover. It corners very well for a car of its size...that must be the tradeoff.

I was browsing in a bookshop on Saturday, and in a book of photos of London in the thirties was a picture of Hyde Park Corner in 1935, at the time of the Jubilee celebrations for George V. The whole road was jammed up with cars and buses, all upright things, mostly British, but including at least one Mercedes and a Citroen, and I tried to identify the various makes ( without much success).There was a revolutionary car in the middle of the traffic jam, though, and it stood out as being twenty years ahead of everything else there - a Chrysler Airflow. They even assembled those at Kew for a couple of years, I believe, and I saw a RHD slightly later one at a car show two years ago, but it was a rare car in Britain when new, even in London.
Wish I'd bought the book, now, but actually most of it was very routine pictures, and it was overpriced.
Actually I have just found a link to the picture, although I don't think the Citroen was right - the Airflow stands out though...

Neat photo, that Chrysler really stands out. Just drop the space before 'image' in the url.
