My car had the OEM runflats which made more noise then a 4 whell drive truck. The Continental Contiprosport 3 was very quiet all the way to 40,000 miles. I just replaced the tires with the same ones, and will try for 40,000 miles again. The ride, and traction was about as perfect as possible. The OEM Bridgestone Runflat I achived about 30,000 miles, but the noise was very loud, and the ride very rough. I would recomend these tires to someone who is looking for a good clean ride with out the noise.
