I'm a fan of the Goodyear Eagle F1's. So I'm keen to know if the standard tyres are any good?
Depends what you get. There were 4 different types on the go for 225/40 R18 GTI/GTD in mid-2013 when they started to be available. More often than not you'll now get Bridgestone S001 which are monumentally sh!te for damp/wet grip and allow the car to tramp freely with very little throttle when pulling away from a roundabout/junction.
If you get Dunlop SP01, Pirelli P7s or Conti 5s then you'll be fine. Uniroyal Rainsport3s are very cheap right now. Excellent wet grip, fine dry grip - but quite soft and wear quite quickly. If I were buying tyres right now, i'd probably go for the F1s or Michelin PS3s in 18" size if the Uniroyals weren't so cheap right now.
