cheers pal.
to be honest the car will be set to run 215/40x17 for everyday usage so a tyre of similar diameter to that should be fine, although the drag tyres will be fitted to a 7" rim.
also, i am not really bothered about them being road legal so prob would go for the 'proper' ones
is this danny guy ok? i.e. will he mind me pm'ing him?
cheers, chad
