With my Fiesta RS Turbo, I run 195/40R16s on my 8 x 16 OZ Mags and although I haven't drove it in nearly a year...I recall it driving like an utter bundle of shite.

But its the wheel I want on my car and the tyres suit the height I want to have my car at.

But 195/45s are a happy medium for an rs turbo (fiesta or escort) imo
