Interesting article, makes me wonder why people fit a wider tyre (tire) than the size designed for the wheel.
You can play around a little but remember that it is only a small area in contact with the road.

1985 GL650 Silverwing another mistake, horrible bike

Me too. I also end up telling people that the number on the tire is the tire's maximum pressure, NOT the pressure they should run their tires at a lot.

I should qualify that, though, by saying that when you add a sidecar it all changes. I run tires on the front and sidecar wheels that would be considered too narrow for the rims on 2 wheels to get a nice flat profile (wears better) and a square profile Shinko 240 on the rear of Mr.H. The 4.50 knobby I run on Eccles is really a bit too wide for the rim but I've been running that size for a decade with no problems and it is after all for winter.

Absolutely Bob. That's why it says for example "Max. Load 805 lbs. at 42 psi. Cold". Everybody should understand that this is the maximum air pressure, that the tire manufacturer is specifying can be applied to that tire, before there's a risk of failure. Anything in excess of that, you're on your own. Right?
So having said that, if one is going to acknowledge that the tire manufacturer knows what's best, why isn't it also acknowledged that the motorcycle manufacturer knows what's best, when they specify certain tire air pressures in their owners manual? For example, my '78 GL owners manual states, "Correct tire inflation pressure will provide best road stability and riding comfort as well as longest tire life. Cold Pressure: Driver only: front-28 psi. rear-32 psi. and Driver plus one passenger: front 28 psi. rear 40 psi."
It always seems to me that many riders, especially motorcycle forum subscribers, claim that they know more about what tire pressure should be applied, than the guy who designed the motorcycle in the first place. And that includes me. Although I'm not sure why that's the case. And it disturbs me!!
