Thanks cSurf


Good point with the cost ratio of RFT vs Non-RFT. I do not have the insurance, as I got winter Hakka R2's.

My GY LS2's @ 17k km had 8mm left. At 18k my tire guy said they look new. I don't corner fast, monthly psi check and inflate 2psi above door sticker levels. I'm think of getting the Viair 00088 88P Portable Air Compressor, only $80.

I'm thinking ahead for replacement RFT's. Likely the Pirelli, p7 all season despite the reported fast wear by some. 1 yr warranty for: "unserviceable due to workmanship, or materials anomalies or road hazard injury"

Rotation, BMW says no. Since mine have even wear and will not rotate in Spring.

It was on a regular Michelin Pilot Sport 2, non run flat.

That was my point.
With these modern cars, with their clever esp, traction etc. etc. etc. you knew you had a flat but t felt like it was down a few psi, not a massive gash in the sidewall with no air in it at all.

M3s have never come stock with RFTs (most M cars come with PSSs [and their predecessors, PS1, 2, etc.] and the Mobility Kit). I believe his point was that they're unnecessary.

I was trying to say that those that have blow outs with run flats shout about their virtues and how they probably saved us from crashing, but run flats are all on very modern cars with some very clever electronics that really do make a blow out far less dangerous than in years passed. I don't think it is the run flat that saves you as much as the cars technology.


One of the guys at the 'ring did 3 laps in his E92 M3 on a flat tyre filled with tyre gunk, I thought he was mental doing it, but he had no problems. I wou;dn't have had the balls to do it though.

To me a can of gunk, a small compressor and proper tyres wins every time, I have yet to experience a car that is not significantly worse on run flats. Why spend all this money on 'The Ultimate Driving Machine' and then ruin it?

I just don't get it.

I think DWS are non-RFT.

Indeed, but in the USA some of us can't have the luxury of dedicated winter or summer tire. So thats why we choose better performing, longer lasting, non-RFT. Even though I don't have anything against RFT, I would of stayed with them if I didn't find a great deal on my DWS.
With 13k miles my Goodyear already had 6/32 left, my DWS have 10/32 with 8k miles i bought it.

Also- I can't help but post this video about the DWS. I ran them on an old X5 and they were amazing.

I am sure the stability system does help in a high speed blowouts, but runflats are still safer in high speed blowout than conventional tires. I have read about incidents where drivers with runflats experience a high speed blowout and did not even know it if it wasn't for the TPMS light. Drivers have survived high speed blowouts before stability systems but runflat tires add another level of safety. similar to the stability system, airbag and seat belt.

Just replaced my OEM GY LS2s with the Pirellis. Trip to Vermont in snow both ways and Pirellis performed better than GYs ever did.

GYs gave me less than 30K miles and are very expensive to replace. Slid out of control on a snowy downhill road once and decided I'd never buy GYs ever again.
