I bought my P5 a month ago, and it had Dunlop SP FM 901s. When I test drove the car, I immediatley noticed how loud they were at speeds over 40mph. These tires are UHP Summer, and have great dry grip, but the noise was unacceptable. I did some research and decided on Michelin Pilot Sport Exalto PE2s. These tires are also UHP Summer spec in stock size. The summer monsoon season has started and these new tires perform excelently in the dry and wet. I have yet to feel them hydroplane in standing water. Best of all, they are silent compared to the Dunlops.
