I also noticed a couple times in dry weather that I had just a slight slip like it was a painted surface. It was very slight and usually when turning, out of a gas station or on an intersection. It's only happened twice. I wonder if they gave up some grip to get better mileage. As long as I know what to look for I'm ok with it if it provides a good increase in mileage. At 3200 miles they seem to be barely wearing but you really can't tell until you hit the 5k mark.I found that the Road 6's are a bit slippery in the corners under hard braking and acceleration,
