It doesn't "erk me off" if someone what's to use a CT tire instead of a MC tire. I think it's unsafe & I see no up side to it.....If I know they're running a CT & I'm riding w/ them, I want to be in front of them...…
Same w/ riders that don't were a helmet, it's your life, your family, you're a adult, do with it as you please...... I've lost 3 friends that were in slow crashes, none wore a helmet. All within 20 miles of home.
