Does anyone know the characteristics of this tire? Is it ridiculously hard?

I've got it on the back of my Fatboy, and with the motor build I've got now, I can't get it to hook up when I'm on the throttle hard. I've got the 211 cams, and once I hit around 3500 rpm and the power begins to come on, it's not long before the tire begins to spin in 1st - 3rd gear. This is no matter how warm the tire is.

Can anyone suggest a tire that will hook up and still provide somewhat adequate life?

 

Hook up????????

FWIW I gave up running HD Dunlops years ago as they are crap IMO.
Dunlop American Elites or E-III's would be my suggestion.

I've heard good things about Commander II's but I haven't tried them myself.
