My Road 5s after about 2500 - 3000 miles. This is them right after doing 40-50 laps of Laguna Seca, running in the faster end of B group, lap times at 1:55. Note that these are already way beyond the mileage I got from the S21 and they look practically brand new. Still loads and loads of tread left.BigOne, do you actually track the Road 5s? You're fast... don't you get creeped out by the 'creep' that you get with siped tires in harder, higher speed corners? I certainly notice it, and it tightens my sphincter and causes my right wrist to rotate forwards...
