Also... most of us have ditched the RFT run flat tires bc the sidewall is extremely hard and makes for rough driving. Get normal Michelin tires with a "XL" rated side wall for added stiffness. This will help with the loss of turn in response you sacrifice with going from RFTs to regular tires. That is the only downside. Regular performance tires will make the car ride SOOO MUCH smoother and nicer.

You might also look for Michelin PILOT SPORT A/S 3+ (all seasons) in the 225 size too.

Don't buy Michelin PS2's. They are an older tire and are not that great for all conditions, especially rain. Go with PSS or PS4 or A/S 3+(all seasons).

Thanks Dack.
I run 225/40 and 255/35 PSS myself. And they are great.
With the Swift springs, when driving passengers on beat-up roads, they can feel a little harsh. Though worlds better than the week I spent on the new springs and shocks with old run-flats! Getting a tire which "rounds off the bumps a bit" at the next replacement interval would be easier/cheaper than getting new, taller, softer springs (or even having the stock M-Sport springs reinstalled.)

As for the fitment comment above, I was referring to the new PS4 ("Not PS4S"), whose virtues you extol in the prior post.
Not sure if they have different availability in Germany than out here in the states.
Actually, I was able to find reference to a 225/40, in addition to the 215/40, for those PS4. But no 255 rears, and the only 245's on 18's have a 40 aspect ratio.

As for myself, with no suitable PS4 for the staggered setup, I'll most likely try the PS4s next year when I burn through my second (current) set of MPSS.
