Arrived to work thinking my journey felt a little ... different, only to find a punctured rear. removed the tyre to find a 2" split in the tread!

Now these XP2 wheels are a tad pricey for tyres, and the bummer is, Neuton do not make a 225/45/18, so on the hunt I went.
Was hoping to get the Syron that Spoons has raved about, only they are out of stock until 20th Feb!!
Looked at prices and reviews, and I really dont want 'droning' tyres, so opted for the Kumho KU31 as I know these are quiet.
Have a feeling they will wear out soon but will monitor it. Even these are £120 a tyre!!
