My recommendation is 225/45. 225/40R18 mostly specify 7.5" rim. Generally people ignore that, but it's not really by the book to do so.
Having said that, the 225/40 on the OEM 7" rims don't look especially baloony to me. 225/40 are a smaller diameter - the sidewall hight is actually a little smaller.
225/45 on the OEM rim have just a hint of bulge depending on the tyre you choose.

So the factory Bridgestone 215/40 tyres on my gen 1 MPS 3 need replacing soon. Is it a good idea to replace them with 225/40 instead? Will there be any issues? My only concern with the 225's is it might make the wheels look chunky and balloony taking into consideration that the sidewall height will increase as well as the width.
Your thoughts?
