180 to 190 rear tire

[rules]

Hi All

So I recently came back to the fold, bought a '19 R1250RS with a mere 12000kms (with all the goodies including factory panniers), and I'm again enjoying the heck out of it.

I do feel though that with the heaps of torque this bike forces onto the rear wheel, that it might make more sense having a 190 back there (it does tend to get a little squirmy when you yank the throttle open) and let's be honest, the 180 looks skinny on a "sport bike".

So the questions are ...

Will it fit without rubbing?
Will it negatively affect the handling?
You'd have to stick to a 55 profile, which makes it slightly higher and the speedo slightly slower, can this be corrected electronically somehow?
Insert forgotten questions here.

What do you guys think?

Thanks,
R
