Tyres? 205 or 225 1.6 Petrol
Tyres on my car are nearly towards the end of their life and I am thinking of changing the alloys at the same time since current ones are well below average in terms of the looks (9 arm original Audi alloys). Considering I have got a 1.6 Petrol, I don't want beefy tyres to shoot my mpg's. Also, considering London's roads, I don't want to go below 45 to kill the suspension.
I've been looking at 17" alloys and thinking of getting 205/45/17 V/Ws. Does this sound a reasonble combination? Could someone give me an idea of how much will 225's affect the mpg's? If it's 10miles per tank sorta thing, then I don't mind. But if it's like 30-40 then it would be a no-no.
Please bear in mind before replying that I drive a Petrol and not diesel :P
