Yeah that happened to a friend of mine too except it was the front tire. The tire rubbed on the caliper and got so hot it ignited a low laying cloud of methane gas from a wetland (West Coast for swamp) and exploded! As it happened he'd put Slime in the tire and when the tire carcass blew out the Slime mixed with the flaming methane and caused a Chernobyl like chain reaction....trust me it wasn't a pretty sight and to this day the still find three-eyed frogs in that marsh..............

"It looked fine, thought all was good."

'Thought' is a real bad word when making modifications.

"As near as we could figure out, it fit ok until the wheel speed was high enough to "sling" the tire a bit bigger,...."

What was he doing like 200 MPH on his Sportster? Even if is 'slung' it a bit bigger, how much bigger could that tire have gotten? 1/64th of an inch? It was obviously a defective tire, or it was never clearanced correctly to begin with. There is nothing wrong with changing tire sizes if one actually knows what they are doing. It is not any dangerous than changing oil viscosity. I do stress the 'if you know what you are doing' part though. Yooz guys are trying to make it into rocket science.

"The tire rubbed on the caliper ...."

How in the world did someone get a tire to rub on a caliper? I'd love to see what in the hell that mess looked like after it was done.

Hey, the guy can probably get away with a minor variation in tire size.

Obigatory Cautionary Anecdote:
My friend Billy put an oversize rear on his Sportster. It looked fine, thought all was good. We went out for a ride; he got a few miles up I-95 and it blew out. As near as we could figure out, it fit ok until the wheel speed was high enough to "sling" the tire a bit bigger, where it got into the fender bolts. Luckily he didn't dump the bike or anything, but the tire shreds did ding the crap out of his rear fender.
I cant believe he diddt feel a rub or anything until it was too late.

IMO; it's not about liability, it's about engineering. Honda and other bike makers spend huge amounts of time and money engineering a bike as an integrated whole. This is especially true with high-performance bikes. Tire testing alone is an enormous investment. Can a different size be installed and made to work? Probably. Is the risk worth the price of a tire? No way.
More of the reasoning behind what I stated was the fact that you have more tire hanging off the rim, which doesnt provide as much side wall stiffness, thats what makes a wider tire bad for cornering.

Thats got to be accounted for before installation. It must clear the swingarm,...even at 120mph.
