Wheel & Tyre size advice {{{please}}} S40 2009

[Justin72]

Hi guys

I have a question re the acceptable tyre size for upgrading to 18" wheels without fouling issues

Firstly I have a 2009 S40 D5 with 17" x 7 et 52.5 "Serapis" rims on, tyres are 205 50 17

I'm looking at fitting an 18" set of "Cratus" rims off a 2012 xc60, same bolt pattern and center bore

The Cratus are 8" wide and have an et of 55, so they will be 2.5mm closer to the strut. My issue really is what width of tyre should I use? I'm thinking 215's as these are standard on the factory 18's but I'm unsure of fouling, or could I get away with 225's

The rolling radius will be fine if I go with a 45 18 tyre as these are fitted to the factory Medusa 18's etc

Just really the width/ offset issue

Any advice would be greatly appreciated 👍👍

I had the 18" split rims on my S40 and the tyres were 215 45 r18. I have seen some people running 225 but only on standard S40/ V50 alloys.
