WS Fiesta Zetec - new tyres on stock 16-inch wheels?

[ach]

Hi guys - I know there are a few tyre-related threads on this forum, but I couldn't find anything specifically relevant to my question, so I'm starting a new thread in the hope of getting some real-world feedback.

My WS Fiesta Zetec is in need of 4 new tyres, after having done 55,000 kms on the original Continental ContiPremiumContact 2s it came with. And as we all know, the WS Zetec's tyre size is rather unusual in Australia, so my tyre choices are limited. (The OEM size being 195/45 R16.)

I think I have the option of going to a more common tyre size without having to recalibrate anything (eg. 205/45R16?) - but I like the current look and ride of the car, so am a bit reluctant to mess with it. (I haven't done much research on this front though to be honest.)

So the top 3 options I'm looking at, for 195/45 R16:
1. Keep the same, ie Continental ContiPremiumContact 2 -> $220 each
2. Hankook K107 Ventus S1 evo -> $170 each
3. Bridgestone Potenza RE050A -> $210 each

(I know there are a few other ones available, eg. Toyo Proxes T1-R and Kumho KU31, but they seem a bit obscure so not in my top 3.)

My question is - does anyone here have any experience on any of these tyres for the WS Fiesta?

I'd be especially interested in hearing any comments on the Hankooks, as they're quite a bit cheaper than the other 2 tyres.

Alternatively, if you've 'upsized' your tyres with good results (while keeping the 16-inch wheels), then I'm keen to hear about it too.

Thanks in advance for any opinions.
