August 15, 4th and fastest run for me
August 16, 2nd run of the day , only clean run of the day for me.
My garmin camera is having issues with gps recorded speed. I will have to try fix it with an update.
I guess your mileage may vary depending on wear characteristics. I was running 5 year old champiro gts past few seasons, I do tend to be a bit more aggressive but having non sticky tires will force you to do that
We'll see how they go this year
