Default Tyre diameter?

Would i be right in saying that a 215/35/18 tyre would have a diameter of around 22mm less than a 215/40/18? And a size of 225/35/18 would be approx 15mm less than the 215/40's??
Just want to check my calculations before i spend some money

spadge - have a look on the toyo proxy site -they list rolling diameter of their tyres. i guess these figures will be simliar for other tyres too.
