Does any one know the largest tyre size for P1 alloys 7X17"?

The are to go in standard uk scooby

I know they come with PZeros 205 45 17
But was thinking of bridgestones or toyos 215 45 17 as replacements as they dont do them in 205 45 17

I want no tyre scrubbing etc

 

215/40x17 at 605mm dia is the nearest diameter to standard (612mm). 215/45x17 is 626mm dia which is too much.
