If a tire is so easy to install it flops onto your rim don't you think it may also flop off just as easily?!?

Continental tires are hard to install because they design the the lower tolerance limit as defined by ETRTO. They want their tires to STAY ON under the most extreme conditions.

Rolling a tire in a corner sucks. When it happens the tube blows and most people think they crashed because they flated when actually they crashed because their sloppy tire slipped off the rim in a corner.

No thanks.
