My darkside rear tire choice was the Michelin Pilot Sport AS. I went with the 225/55ZR16 size. I'm running 32 psi. The adjustment period was very short, maybe 100 miles. Now, I don't even think about it. I rode with a pretty fast group of sport-tourers last weekend and their comment was "you've made a believer out of us". Honestly, the limiting factor is NOT the tires on my Rocket but it's the footpegs. I was continually grinding on the peg feelers but the tires were totally secure. I will say though, that I could really feel that 800 lbs. as I threw it into the curves. On a big "power cruiser" like the Rocket, I will never run a motorcycle tire on the rear again. My handling with the Michelin Pilot is as good as I could want. The only difficulty I had was finding a dealer that would install the car tire on my rim. I finally found a chopper shop that would do it. Really, I couldn't be more pleased with it. The only people I hear warning against it are those who have never tried it. Conversely, I still am not aware of anyone, who HAS tried it, that didnt' like it. Enough said!
