A 5.5 to 6.00 rim,you would be able to fit 180/55,190/50 and 190/55,any bigger isn't recommended 3D Ultra Supersport | Avon Tyres and Dunlop say exactly the same,so will most of the big tyre manufacturers
so now we have that both 749 and 999 have same rim width, but diff tyre fitment,, mmm" interesting ",, so should be no inherint prob in fitting 190, ( as OP ),,, what about matching front and rear profile ??
FFS, why fit a tyre that is a fashion fitment width instead of the right tyre????????????? The rear profile will always be a dogs dinner with a 190/50, so gives a flying eff about the front!
No,otherwise the manufacturers wouldn't put it in their fitment books,true some tyres have a flatter profile than others,then you have to watch things like huggers,as they're usually bought afterwards.
The 999 in WSBK was often run with a 200 profile tyre. I assume that the teams were fitting 6" rims to their bikes. Just sayin'.
They prob did,but when you're talking out slicks,their dimensions are slightly smaller than a road tyre.
