OK, confirmed its 18" wheels and also, got the exact same tyres as you... I remembered Michelin X but didn't know the sub brand was The Pilot Sport 4S.
Also, I don't have the Magnetic Ride - no switch or suspension with a lightning bolt when I start up.
Back round again, even with Comfort setting, it's harsh. I tried Dynamic today on route home. It's tight, and then hit a small speed bump at 20kph, and my god! It's likes I ran over a dead animal or something!
If you don't have magnetic ride, the 'comfort' or 'dynamic' setting is presumably not actually altering the suspension, it'll be on standard fixed rate dampers, it'll just be changing stuff like throttle response and change points of auto gearbox etc.
