Blackcircles.com 5% discount
I have just ordered 4 new tyres for my A4 Avant from Blackcircles.com with a 5% discount.

They're not always the cheapest as it depends on the specific tyre make/size combo but 5% discount makes a difference. I tried other tyre resellers across the web and out of the phone book but they came out the cheapest for me - over £100 cheaper in once case!
I got 4 Dunlop SP9090 235/45 R17 Y's as I have had two sets - done 30,000+ on each set and I'm not a steady driver either! Also, personal preference but I like them better than Bridgestones and Pirellis before.
They are priced at £370 F/Fitted after discount
