Run-Flats or Non Run-Flats

I know that this topic has been reviewed many, many times over the years and I myself have experienced run-flats on BMW's about three years ago on two different BMW's of mine.
I now have a new Z428i and I will want to replace the summer high performance tires with an all season, ultra high performance tire. My delemma is this, non -run flats are cheaper and I am wanting the Bridgestone Pole Position non-runflat. However, over the years I understand that runflat tires have improved a great deal. Offering a smoother, quieter ride over its' predescesors. So, I am also leaning toward the Bridgestone Pole Position Run-Flat tires. Anyone have some imput I can use to make my decision. Thanks

Correct. The Bridgestone Potenza RE960 A/S Pole Position RFT run flat tires are quite a bit better in regards to ride quality than most older generations of run flat tires (especially summer run flat tires). So you can stick with a run flat tire and improve ride quality at the same time.

Thanks Gary, for the recommendation. I purchased the Run Flat/AS Bridgestone Pole postion Ultra performance tire from Tire Rack last night. I appreciate your help and look forward to doing business again. crm 114
