Does anyone know what the specs are for the factory 18 & 19" alloys?  Ideally want to get some 19" aftermarket alloys for my estate when it arrives but not sure what offset and diameter to get.  I assume the PCD is 5x112.  Also re the front and rear the same?

Thanks for that, would ET45 be okay as that's what most aftermarket ones seem to be.  Are there any other important measurements I need to take into account that I've not listed?

Yes 1mm isn’t going to make any difference at all.

 

You will probably be fine anywhere between ET40 - ET50

 

The only other bit you need is the centre bore, Škoda use 57.1mm, so some wheels may require a spigot ring to reduce the centre of the wheel down to 57.1mm.

_{Shame I have 235/35 19" for the mk II  and the mk III Superb is 235/40 19"}
