    Hi I've recently upgraded the alloy wheels to some genuine rs6 S line style alloys. They are on my 2004 a3 sport with the standard sport suspension.

    Unfortunately the MPG has suffered on my car which a considerable amount. I have being messing around with different tyre pressure combo's but still cant get it right.

    Anyone who has done the same offer any advice whether its a pressure issue or the fact my suspension is higher than a s line that's causing the mpg reading?

    Tyres are 225/40 r18

    Thanks!

    Thicker tyres make econony worse fact. You got budget tyres or old sporty ones? They can make it worse. I belive eu regs recently made tyre firms discontinue tires and re-design them to certain economic and sound levels. As I was told when hunting a set of falks.

    About 8-10 mpg it has dropped :(

    The tyres are Nankang. These im pretty sure
    Nankang NS-2 225/40 R18 88W
    Nankang NS-2 225/40 R18 88W - mytyres.co.uk

    I just cant understand how S Line a3's with the same wheels can achieve higher MPG but put the alloys on a sport and its such a drastic change.

    the poor mpg may be caused by the tyres themselves! certain tread patterns don't lend themselves to good fuel efficiency.

    Any tyre with an E rating isn't going to give you good returns
