Well, I have the OEM 18s now with 45 depth tyres that fill the arches nicely.
There are 25.4mm in an inch so thats a total of 502.2mm for the 18 inch wheel and 45mm tyre and 517.6mm for the 19inch wheel and 35mm tyre.
So, the 19s with relevant tyres will fill the arches by 7.5mm (i.e. half the extra height) more than the currents et up which will be nicely snug. In fact, after all that calculation, I just realised they are exactly the same size as OEM 19s, so any old pic answers the question LOL!
