Mounted up a Cooper Zeon ZPT 245/50r 16 on my 2008 Rocket Std. Did it for sidecar use but of course I had to try riding darkside before hooking up the hack. Absolutely no slow speed handling! Keep wanting to fall back on the flat tread and go straight. Not bad at all on the highway though. With more time I could probably get use to the ackward feel of the tire and a narrower tire would most likely not behave so badly at slow speed. But for me and the riding that I do I will be going back to a motorcycle tire on my spare rim for non hack riding. Has about 1/4" or so clearance on the shaft drive side. I have taken it for several rides with no rubbing. Running with stock shocks.
