Just removed the original run flats and put on the new Yokohama 195/55/16 tires - cooper hardtop. No need for run flat since I do have a spare and I am so glad. These things make me feel like I just got a new big car. Amazing improvement in ride, road noise, and inability to feel every little bump in the road. I do have them up at 50lbs. since I drive easy and it's not super hot right now. Check them out if you are in the market for tires. Discount tire had them for 125 each.
