Point of information - any car tire fitted to our bikes will compromise the handling and steering making it more difficult (add'l effort and countersteer required/less responsive to rider input) to maneuver than when fitted with a motorcycle tire. Don't let appearances delude you, Hellfire. If you push hard in the twisties or just like to regularly power out of turns in a aggressively and in a low lean, you will ride well up onto a CT's unreinforced sidewall.
I just took this excellent, high quality CT off my Rocket after 6700 miles
PROXES T1R | Toyo Tires and returned to the Metz, because riding a CT on this bike, is neither a smart nor a safe thing to do, IMO. Prior to my Darkside experience with the R3 I ran approx 25,000 happy and trouble free (cuz you couldn't ride on the sidewall due to a lesser max lean angle) miles on my VTXs shod with car tires,
There's no assurance that you'll have a mishap or tire failure, but the risk of doing so is real and I chose not to make my riding any riskier than it need be and already is. Just my choice, others certainly will disagree...

You may find the compromises acceptable in spite of the added risks.
