You want 225/40/18 tyres to maintain the aspect ratio although without getting the calc out the tyres size you mention would also be close, but why go narrower ?

An 18 on standard suspension will look like a monster truck IMO
et 45 is too high mate. your front wheels would rub the front struts.
If your wanting a comfy ride like you say I'd stick with 17s.
if i used 10mm spacers would i be needing longer wheel studs aswell ?
any idea where to get the longer studs from ?

If there aftermarket they will prob be tapered and not radius like the OEM wheels.
Don't forget longer locking bolts.

ok, using a 10mm spacer it looks like then i'll be needing a 12mmx1.5 tapered wheel bolt with a thread of about 40mm.
