Lee,
I have used the coker tire with good results! It did seem soft but we ride kind of hard (fractured a rear rotor, had to replace the bearings). We had it mounted tubless, the company said that it was built for that but listed tube type for the old cars!

I just ordered this! It is taller than the fermoza we are currently rideing(good tire by the way) and reportedly tough as nails from other sites!
Might see ya it Texas!?!?
Smith8833, unfortunately, the narrower swingarm & 3" wheel on my older framed Sportster will not take a tire wider than a 150. 
Come on down to Texas.
