I was wondering what the standard wheel size is for the 1.6tdi and do they use the same 5 speed box including ratio's across the range?, the only reason I ask is when looking for wheel & tyre alternatives and using a tyre size calculator, if I go off the size I have 205/40/17 and go for say 215/35/18 which is 2% difference which is fine but if the standard size from the factory is say 185/60/16 then this puts me at a 3.3% difference which is outside the recommended specs, cheers.

205/45/16 is a popular size for the Fabia
