hi, I have a 2014 black edition avant tdi 150 that's done 7,000 miles and the front tyres are already done to 4mm and the tears are 7mm. I drive mostly back roads and occasionally the motorway and won't say I was an aggressive with the Car. I have checked the tyre pressure and running 35 front and 33 rear. It looking like I will get just over 10,000 out of them. My old a3 black edition got 18,000 out of a front set. I do notice that I can easy wheel spin the fronts pulling out of junctions. I am running contis all round. What are you guys getting out of your front tyres?
