You will not get heat into the tyres at the right rate and your actual contact patch will be no bigger than with a 7.5" rim.
Grant, this strikes me very much like my recent clutch issues!!

I am not up on physics and after my clutch dont care but I know of an elise that was running 215 rears and was untracktable up until 3rd gear with a recently fitted Jackson but he has since gone to 245 rear (not sure of the exact sizes but know he went up 3 sizes) and now the car grips like a bastard, even in 2nd it only scrabbles now......

There is also lateral grip to take into account 9" wide rubber will let go a lot later than 5.5" rubber around a track.

Like Jon said Zonda's etc are not fitted with 335's etc just for the looks
