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
