Here's another 'flag on the field'.
All new tires require a 4,000-mile break-in period before they reach their rated coefficient of rolling-resistance, and that coefficient falls over distance, ultimately reaching it's lowest possible value, when all the tread has worn away.
Car guru-wannabes need to arm themselves with these fundamental basics before ever opening their mouths, or risk losing all credibility, of which, it's my opinion that, Wayne has none.
