Need some advice....
Have upgraded from the sport to the s-line - Would the RS6's with AVON ZZ3 225/40Z R18 88Y tyres make a difference on fuel economy? Mine's gone down by about 15-20%!!

Also Audi says the pressures should be 30/29, kwik fit 32/32 - any suggestions?

Finally any suggestions for patching up alloys - any products/mobile repairers...

Cheers RegE
