Mmm food for thought.

PS4 should provide good grip regardless.

Focusing on 225/45/18 or 235/40/18 now as they show up as in tolerance on oponeo website, 225/40/18 don’t.

However enter 7.5 for wheel width and 235/40 aren’t listed.

18” Midir 7.5 wheels

Don't know whether this helps. I've taken the info from a Bridgestone Tire Safety Manual.

Cheers,

Based on those numbers I'll probably go:
215/45/18 or 225/45/18 I think, car is a commuting car, so I want decent tyres, always bought the best I can. Beyond that I think got to be sensible re what it's used for.

The other car, now that's different, equally might sell for a Lotus/Porsche or E92 M3
