17in Tyre Size for OZ wheels

[Masterkm]

I have got hold of a set of OZ Nova 17in Alloys which I am going to do a refurb to and keep as my winter wheels but struggling to get the right tyre size for them. They are ET35 8J rims and currently have 21545R17 tyres on them but I feel they are not right.

My current setup is the SEAT BBS Sport 18in ET51 with 22540R18 tyres.

What tyre size would best suit my winter alloys that would kind of match the 18s?

PS the car is also lowered on coilovers so would like to minimise rubbing etc

Thanks

225/45R17 will be the closest match in terms of rolling radius (about 0.5% difference). The BBS SEAT Sport wheels are 7.5J, I think, which means that the 8J ET35 rims will be 10mm further from the strut, but 22mm closer to the wheelarch. Are you currently running spacers?

Thanks for the reply. Not running spacers with my 18s atm
