Elvis, didn't mean for you to get jumped. I am with you. I put my first car tire on last year on a 2005 Goldwing. The ride was smoother and it was a run flat tire as well, but breaking no different. It was an ABS model.
As far as grip, I highsided my R3T 2 years ago when a car stopped in front of me. As I hit both breaks and tried to maneuver around the car, the rear got real squirly. She ended up throwing me and rolling over me. With the car style position of the rear peddle, it is difficult at best to feather the rear under emergency conditions. I want the Car tire to help the rear stay hooked up to the road in an emergenc.
