Does anyone have any experience with Bridgestone tires? <p>Currently, I have Michelin PS A/S on my R, and they are wearing quickly. I am thinking of preserving them for the winter and getting a set of Bridgestones for the rest of the warmer months. The reason I am going with Bridgestone is due to a friend who has them available at a discount. <p>I was hoping to find any information/ experiences that anyone has had with either the Potenza RE050A Pole Positions or the Potenza S-03 Pole Positions. I have not heard a lot of things about the bridgestones (good or bad) but was wondering if they at all compare to michelin's/goodyears. <p>Thanks in advance for any info anyone has.
