I had 30mm Schwalbe CX Pro tires on narrow rims on one of my bikes. When the front tire lost air that bike was impossible to steer or maintain control of. If riding at anything other than a near crawl and the front tire flatted, you'd crash before you had a chance to do anything, That was without the tire coming off the rim too.
