Hi All,

After my second pothole caused flat on my non-runflat Michillen PSSes (and resulting tow to shop due to no spare tire), I'm switching to Pirelli Cinturato P7s runflats, which Tire Rack promised would have a softer ride than the PSS with "2 -4 times the mileage." I will post my take on the differences.

In the meanwhile, I have three 19" PSSes with about 3k on them in excellent shape for sale. Two rears 255/35 19 and one front 225/40 19. I'm in sunny Los Angeles. If I'm posting in the wrong forum, I apologize. I couldn't locate instructions on how to post in Marketplace.

Hmm. I just took off the 18" Pirelli Cintauro run flats for a set of BFG non runflats. They look pretty funky and I was thinking of going with the PSS. I've run them before on my 221 and they're usually very smooth. They do wear quick though. On the 221 the staggered rears lasted 9k miles. Fronts lasted around 12k.

What's the tread depth remaining on yours if you know?

I am finding the Cinturato P7 All Season runflats to be less crashy than both the OEM Conti runflats and the Michelin PSS non-runflats. For me, they are a good compromise, although it's likely that at 10/10, the handling is not as good as the PSSes, which are max performance tires. But I don't run the car on the track anyway.

Mike, I don't know how to reach you off the board, but I still have the like-new PSSes, and noticed you are about to buy some. I can send you pics and tread measurements if you (or someone) explains how to contact a member off the board.

Thanks all.

Hey, I ordered a set of PSS and they just came in. But to contact a member privately click on their handle and choose "send a PM" (private message).

So when you say "crashy" does that mean they're not as compliant and don't have as much "give" in the sidewalls as you were hoping?

Yes, by "crashy" I mean that to me, they have too much impact harshness and noise, even on small bumps like Botts Dots, the raised lane dividers on California freeways, and on potholes. The Cinturatos feel more compliant, and deliver a smoother ride.

Thanks for the PM instructions, and good luck on the new tires.

Thanks. Got them mounted up today and they ride like I remember them from my old S550, S430 and S500. I will say if you can get past the look, the BFG Comps cost a good deal less, ride just as well and last twice as long. My old set is on EBay now for a steal, with less than 400 miles on them. Still have the factory markings on them.

Ok, I see what you mean about them being a little "crashy". The rebound is quite a bit quicker and the car definitely bobbles around more on uneven terrain but I like the ride overall.
