I'd like to issue a challenge of my own. I say that placing a CT on the back of an FJR is just as safe if not safer than a motorcycle tire.
I have no quibbles with the safety aspect of car tires. I'm sure they go round and round like an mcy tire.
My issues is why you would put something that handles worse in the twisties than a mcy tire? Sure, you can ride it in the twisties and some crazy nutter on a car tire can race another on an mcy tire and they can go fast. But besides some sort of longevity advantage, would you put a worse handling tire on your bike?
Car tires - make the bike handle like dog poop for a long time?
Head to head...same rider, a mcy tire will perform better and have a better feel in the twisties.
After hearing from two people that I have ridden with and respect take off a car tire because it took out that the fun times in the twisties, that convinced me. It's that last 10% of a well handling creamy smoothness on a sweeper or twisty that gives the wow factor for riding for some of us.
For others, its longevity of tires (yawn).
I have no problem saying that in the right hands, a CT is safe (yawn)...but don't tell me that a CT will give you that same warm and fuzzy feeling in the curves...cuz I have two former darksiders that have told me that they had to take that POS off.
