Question Run Flat vx regular tires?

Does anyone have experience with run flat tires and if so what is your take on them? How about dry cornering performance between a regular and run flat? I see a tire I am considering comes in a run flat and I am now not so sure I want them until I find out more about them. Bridgestone Potenza Pole Positions.

Everything that I've read about run flats in the performance car world is to stay far, far away. I'm not sure about the actual grip and performance, but ride quality is much worse than their conventional siblings.

My only experience with them was on a 335i, and the ride was definitely not as smooth as I'd experienced in regular-tired 3-series.

I say get regular tires and be done with it. Throw a can of fix-a-flat in your trunk if you're really worried (but then again, the tire shop that replaces that tire will probably hate you for the mess that it makes).

Run flat tires are kryptonite to performance. They are heavier, less effective at soaking up bumps, and more expensive than their non-run flat counterparts.

How about they're kryptonite to everything?

Run flats shouldn't be on any car except Hummers/Humvees, and the Batmobile.

LOL! Well run flats are definitely out not that I was really considering them in the first place as I thought there would be a problem but wanted to be sure.

I am looking at Bridgestone Potenza RE050A Pole position in Front, either 205/50 YR 17 or 225/45 ZR 17 and Rear 255/40YR 17. Nowhere in tire rack is any mention of run flat on these tires so I guess I am OK. When I do call to order I will be sure to axe about the run flat to assure they won't be that type. According to the reviews at Tire Rack these are right up there with MichelinPS2 tires.

The Bridgestone Potenza RE050A Pole Position is an exceptionally good tire - you'll be pleased with them.

But, realize that tire preference is like motor oil preference - everyone has one, but rarely is a concensus ever reached.

Cheers!

Thanks to all

I knew something in the back of my mind was saying to avoid the run flat type now you both brought it up front again. Thanks again now back to my quest.
