Change of rear tyre profile?

[DuraAce]

Bike runs 190/50 on the rear but I have a few free 190/55 tyres available to me.

Would it handle better or worse? Or should I just buy some tyres of the right size?

I know it'll affect the speedo reading a bit but it's for my track bike so not worried about that

Hmm nothing to lose by trying it I guess, I'll get one fitted and see what the swingarm and hugger clearance is like.

Reckon it'll handle much different? I'll probably not even notice as I'm crap and slow!
