Recently ruined the two front OEM Goodyear Run Flat tires and replaced them with the new Firestone Indy 500s. I don't know if it is the Firestones or being non run flats but it made a huge difference in the ride. Takes the bumps and pot holes so much better. I was so tired of the ride before I changed, I was thinking about getting rid of it. It made such a difference that I am liking the car again. If you don't mind not having run flats, give the non run flats a try and I think you will be happy with the change. Just my 2 cents worth...

 

I think i will try that and see if i will love it more

 

Beijing- I have almost 13k miles on them and 4 months short of 2 yrs. and they still look new. But I don't drive as hard as some do. After 3 tickets, I have learned to keep my foot out of it most of the time.
