Advice on tyre size please.

[Scoobyghost]

Right, one of those tyre discussions again.

I'm in the market for some new boots on the old girl. I've had Goodyear eagle f1 gsd3's for the past 12k miles and I trust them with my life now. I'm on standard wheels if that helps [emoji12]. So far I'm struggling to find them in my current size of 205/50/16. From what I've found I am meant to have 205/55 as standard.

A couple of points and options spring to mind. Is it possible to go 215/50 or 45 on the standard rim. If not and I'm all out of options for the gsd3, what other tyre should I be looking for of equal quality.

Rim for clarification
