So I have been wanting to get off run flats for a while with my eye on Firestone Indy 500s. But I live near downtown Dallas with average roads near tons and tons of construction. Since I bought my car in late November I have warrantied 4 run flats for screws in that time (including both my fronts at the same time just this month).

The ride is a bit harsh but they have been a savior a couple times. I have the normal Bridgestone RFTs...are there other types that are more compliant and would help soften my ride at all?

I've run both the Dunlop and Bridgestone OE RFts that came on the 135i. I wasn't impressed with either, but did feel that the Bridgestones were slightly better. A friend of mine just bought a CPO 435i, and it has an even better set of Bridgestone RFTs on it.

That said, I love my Michelin PSS, but if I absolutely had to settle for RFTs, I'd get a set of Michelin Pilot Sport Zero Pressure.

Michelin makes a PSS ZP, but not in our sizes.

If you're willing to upsize to 225/255 you can get Pilot Sport PS2 ZPs.

But PS2 is an old tech tyre..

Id pick either the RE050a, Pirelli Pzero or Goodyear Eagle F1 Assymetric 2 if it had to be a runflat.

The Goodyear however is fragile and a big pothole will tear the inside of the sidewall, causing a hump. Steering feel is vague. You have to point and trust the tyre will get you where you point it.

RE050a is an old tech tyre but i prefer these over S001 RFT as they seem to grip better. The S001 is quieter and arguably lasts longer and resists abnormal wear like feathering, sawtoothing, scalloping better than the RE050a.

Pirelli Pzero is a bit of a surprise for me. It gives you high expectation because of its name synonymous with F1 but i've had mixed experience with them. I dont know if they changed the compound at some point?

Appreciate the feedback. I could carry 1 spare but I don't do much driving in places where you can pull over and safely change a tire without being in imminent danger of getting run over. The cost of runflats is crazy expensive though and just may push me to regular tires.

So I went through sort of the same thing driving in the DC area (lots of crappy roads). And I could not find any place with those Indy 500s.

I decided to go with 225/225 Michelin AS3+. There is some extra sidewall protection from upsizing. They aren't runflats but I keep a mobility kit in the trunk and have roadside service. I like how they ride and grip better than the OEM tires.

Okay, but most other RFTs are complete dog shit. As I said above, Michelin makes a PSS RFT, but not in the correct size a 135i.


I run 225/255 Michelin PSS, and a BMW M Mobility Kit in the trunk that I don't ever intend to use for anything aside from the compressor. My 135i is a 3rd car for me, but I still have total peace of mind driving it.

I don’t have concerns either.

This is my DD so the concerns are a bit different. While my wheels and rims are covered by BMW I may keep RFTs but they will replace any OEM or aftermarket tire and rim that gets damaged for $50.

Wish RFTs didnt suck.

I second your daily driving concern. I do 25K miles per year and pick up at least one construction screw/nail/you name it every year.
Peace of mind is the key. It's good not to have to pull over 6am in the morning in Michigan weather to change a flat like in the past. I just drive to destination and leave it at the closest tire shop.

My Bridgestone blizzak run flats are actually quite decent. The OEM continentals all weather , well, not impressed and with weird balancing issues as they age.
I will be looking for a decent summer tire rft next spring.

I am actually wanting to upsize to 225/255. So these MPSZP could be the ticket. How is the ride? Is it any more compliant than the bridgestones or am I just shit outta luck with all runflats due to the nature of the tire?

EDIT: The the MPSZP have really good reviews for runflats on tire rack, and good numbers for comfort and noise.... hmm. Thanks guys
