Had Michelin PSS for 18,000 miles. They were down to wear bars. Replaced with Pole Positions. Fabulousvride, low noise considering Max performance summer rubber. Overall handling is 95% as good as PSS. Wet traction is better than PSS, and ride quality is same or better. Car handles and tracks perfectly. Running factory psi specs of 35/36. Wear rate at 1,700 miles measured using digital laser tool. Expect to see 19,000-23,000 before wear bars. Supberb for a performance summer tread. Balanced perfectly using standard equipment. No road force needed. Love these Bridgestones. For a Michelin guy, I am impressed.
