How much did you pay for the Tire warranty? How many years? What tire size?
 
Thanks!

A lot of the comments about wear fail to distinguish between the base tire and the sport package tire, which is very sticky and has a very short life. In my experience the RE050 becomes very noisy long before the tread wears out (around 10K miles on the current set, with plenty of tread left).
 
As for the concerns about the snow traction of the summer-only sport package tire on a $45,000 car, well, this raises questions about the need for anything beyond a very rudimentary education to do well in today's economy.

The Michelin Pilot Sport PS2 Run Flats on the BMW 335iS I am driving [ includes MSport Package ] are 225/40ZR18 fronts & 255/35ZR18 rears.
 
At 24,000 miles, I perceive no significant increase in noise, so far. Tread is wearing well. The Goodyear Run Flats on the 2007 Corvette I drove for over 30,000 miles were well worn, and noisier, but these Michelins appear better in every aspect.
 
[[ Living in the Atlanta area, the snow performance is not a high priority for me. ]]
YMMV.

For Run Flats, these are the best I have yet encountered . . .

Ray, thanks for the info. I don't see them in 17" on Tire Rack. Wonder if they are available elsewhere.

I have Continentals ExtremeContact2 runflats, sports package, same tire widths sizes except 17 inch wheels. 20 thousand miles, the wear seems very nicely (still good treadlife left, it seems), at this point still great dry traction and marginally lower wet traction vs. new. The tire has never been quiet on rough pavement, I think there is a gradual noise increase. As a replacement I'm considering Bridgestone 960AS RFT, which tirerack pegged as best all-season run-flat. The wear index is higher than the Contis, but this doesn't mean sure thing (each mfr. uses different scale and benchmarks).

The choice of sizes is extremely limited in RFT category. The manufacturers don't make even half of the sizes of regular tires, so there is no surprise you can't see them. They probably don't exist. You may consider changing the size a little bit (e.g. from 255 to 245), which usually means the radius will also be slightly different, but as long as left to right match, it's OK.

AGREE with nkeen 100%.
Had used run flats on 2 Bimmers (2001 330i & 2006 330i) until I smartened up and changed to standard Michelins 4 years ago. Never looked back. As nkeen states, wear too quickly.
My words.....son't waste your money on RFTs. Yes they do serve a purpose but my experience, keeping a spare "donut tire" in the trunk + all the required tools including a jack that simply plugs into the carr's lighter solves all the problems that "may" arise.
Well stated "nkeen".

Has anyone gone to the Bridgestone 960AS RFT from non-RFT? We had RFT on a 325 that became exceedingly noisy at 10,000, so we went to Michelins, got over 50,000 smooth miles, but now it's time to choose the replacement.

The RE050 excels at dry handling and they're not bad in the wet. They have a really sharp turn-in too. When they are in their prime they really mean business, but they don't stay in their prime for long. I think the wear issue is more related to the no-compromise high performance nature of the tire -- their wear rating is a solid 140. The noise they make is like a rough, oscillating, grumbling rumble whose pitch varies with speed. It is independent of any road noise generated by varying road surfaces (milled concrete, etc.)
 
I am loath to switch to a non-runflat as I believe that the car is engineered to work with the stiff sidewall of the RFT. I swap to 16" LM22 Blizzaks in the winter.

The Michelin Pilot Sport ZP [ run flats ] are rated at 220.
