Replaced OEM Goodyear F1 summer performace tires. The OEM tires had good tread life after 15,000 miles, but they never tracked to my satisfaction. I had to constantly make small steering corrections. I noticed immediately that the Michlins tracked bautifully requiring little steering input when cruising the freeways and city roads alike. They are very smooth and a real pleasure to drive. Since we have had not rain, snow, or ice in New Mexico since I got them, I cannot comment on how they would perform in those conditions. In the dry, traction and handling are superb.
