Thanks for the info, I have been to have the tyres fitted this morning and when I turned up they were going to fit Kumho 712s. £70 per tyre when I asked about the newer KU31 they were £90 fitted so for the extra £18 per tyre I went for a set of Goodyear F1s GSD3s. Did'nt really want this kind of high performance tyre but for the extra few quid thought the brand name reviews etc etc justified the decision.
