Just wondering if anybody could give me a bit of advice guys... Had my car in at the dealers today to have my passenger seat fixed. I have a 1.9Tdi sport, and Edinburgh Audi do a standard check of the tyre depths. My front is coming in at 4mm, and my back 7mm. The car has done about 9500 miles. My dad seems to think its my driving, but I have assured him that this is perfectly normal! Haha. Can anyone shed any light on whether this is right or am I just using **** tyres. (Think the standard ones are Contis).] Cheers for any help!
