I replaced the original Bridgestone Dueler RTF's with Dunlop SP Sport Signature about 3,000 miles ago. What a difference! The car feels a lot more comfortable, it is much quieter, it does not hydroplane and it is actually drivable in the snow. They really transformed the car. That's not because the Dunlops are so great but because the Bridgestone RTF's are so lousy. Ditch the RTF's and with the money you saved buy a donut spare.
