Ha! Well spotted - I couldn't remember what the rears were - they are Nokian Z G2's . In fact the fronts aren't even Avon! - they are Yokohama Advans!! Result
.. I was originally going for a set of Falkens but they didn't have any left in stock so agreed on this set. The Nokian and Yokohamas are well matched and much better quality so very happy!
