I have about 3500miles on the original PILOT ROAD 4'S basically about half getting to the mountains and half running the bike at it's limits on twisty roads. I am not far from needing a rear and the front does not look great, sort of cuppy. I am anal about air pressure Running 41 or 42 rear and 37 or 38 in the front. They have never ever done anything weird or bad. They are easy to warm up turn in nice and grip solid at all angles. Best rain tire ever. Occasionally I ground the peg feelers. I doubt I will get 5000 and I know of people getting close to ten with the PR4 on other bikes. I probably will buy them although the BT16 pro option is tempting and cheaper. How are your tires holding up for you?
