Getting a little confused, I was going to go the same as MADAde with 205/40' on the front and 215/45's on the rear, but in the end went for 215's on the front as I didn't want a lot of stretch but there still is

/ so was thinking if I went for 215's on the rear I'd get stretch again but would the higher profile of 45's reduce that more?
This was yokohama prada's on the front but am I right in thinking it depends on the make of tyre? As toyo's seem to come up wider than the actual width quoted?
So should I look at 225's? I have 235' s at the mo but look like tractor tyres tbh, these are old yokohama a520's I think still with a 40 profile but I don't really like how they look, I'll get a pic in a mo.
This is for a 2wd saph btw, so wanted wider rears for grip obviously.
Can anybody get pics up of there and state the tyre sizes pretty please?
