C200 AMG Line (2015)
so a year ago i switched from runflats to non-runflats, and i noticed recently that the outsides of the tires (even the rears) are wearing WAY faster than the middle..(and no my tires are not underinflated). Is this because the suspension is tuned for runflats and expects a harsher impact on the side of the tires because of runflat's stiff sidewalls? I mean, after one year and probably 11-12k miles the sides of the tires are almost to the wear bars..wtf..500+ treadwear rating on these things too.
My plan was to throw the runflats back on a couple months before the end of the lease which is may 2018 but i doubt ill even be able to stretch these tires until the end of the summer. Sad!

2017 C300 Coupe, 2013 Cadillac ATS 2.0T
Just an interesting thought. I recently replaced my 2013 ATS' RFTs with N-RFT Pirelli Centurato P7+ All Season Grand Touring on my 2013 ATS. They certainly smoothed out the ride and made it much, much quieter; although, I did give up some performance. What I found surprising was that this new N-RFT ride was now as quite as the C300 coupe's with RFTs. To me, as I found the MB's ride with RFTs (Continental ProContact SSR) was very quite to begin with, could this be due to MB's "sound-proofing," or are these RF Continentals really quiet?

I switched to regular tires about a year ago, I'm going to get a set of PS4S later this year I think - just need a bit more of a performance minded tire from what I have now. The dynamics of the car are much better without those run flats. They were so soft in the corners!

well, i got my tires measured at my dealer, rears are at 1/32 and fronts at 3/32, both after 10k miles. i ordered cheap (albeit good) sumitomo non-runflats and am having them installed on saturday, and at the end of the lease 13 months from now ill throw the runflats back on. cant believe the P-Zeros wore out in 10k miles..

So I installed Sumitomo HTR A/S P02 tires this weekend and they have transformed my car. The improvement in ride comfort is even more noticeable than the initial switch I made from the RF's to non-RF pirellis last year. Drove about 300 miles on them this weekend and I am very happy with them so far.
