225/55 16 was that a typo? ...

Oops. So it was.
I'm running 215/55-16 tires on 16x7JJ rims with a 40mm offset.
Stock are 185/70-13 or 185/75-13, depending on the year of the car, with a 24.5mm rim offset.
Stock (185/75) tires are 23.9" dia and mine are 25.3" dia. This raises the car by about 3/4", but I've got lowered springs so it balances out.
But, the stock tire width is 7.3" and mine are 8.5", about 1.2" wider (0.6" per side). As well, I've got rims with 40mm offset, but my 4x100 adapters are 25mm thick. Add this to the std offset of 24.5mm and my tires are moved out by another 10.5mm (~0.45").
So, effectively I've moved the outer wall of each tire, outwards from the stock location by ~1", enough to hit the wheel arches.
I went with the 215's because I have a 3.45 rear end (<i>also, they came with the rims</i> [;)]). At 70mph in 5th this drops my revs to 2670rpm vs 2825rpm for the stock tires. To be honest, I'd love to get a 3.08 rear end. Drop my revs to 2385rpm at 70mph.
