Different tire manufacturers make different profiles - my 190 Metzeler M5 is about the same shoulder width as a 180 tire from another manufacturer (can't remember which one). The point is that a 6" wheel should have a 190 tire to maintain the shape that works. I hope you find a 190 tire that fits - much better result - you deserve best result with those wheels!

Still can't tell from the photos - is the conical spacer there? Is there a spacer between the wheel and hub?

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the air—these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

190 vs 180 is about 0.2 inches added to the width on each side of the tire.  It is not much wider and would probably fit but just be close.

I might be the lone ranger here but I think you should paint them white.

Good to know waytogo

Top speed will make the tire expand, diameter, so depending on where your eccentric hub is positioned (chain length, wear, sprocket size) I suggest keeping an eye on the tire just to be 100% sure there is no contact against the front section of the swingarm.

wouldn't that depend on tire shape and tire pressures

Maybe - I don't know....

I contacted a couple of manufacturers with the question when I switched from 180/55 to 190/55. Only Metzeler replied and the answer was reassuring - can't remember exactly, but I believe it was 4 or 5 mm expanded radius at 275km/h. Other manufacturer's tires might perform differently - if so, the eccentric hub position can become a critical factor - at least in theory.
