Launch control and traction control are usually based on wheel rotation differences, and they are independent of power available. Detuned driving modes or special power limiting modes are controlled by throttle position and rpm.
In neither case would retuning for power have impact, except that these modes would become active earlier. If you defeat these modes, you still have a safe bike if you're sufficiently skilled.
The same can probably be said about running a car tire. Once you get used to it, you can apply what you've learned to your riding situations.
Except that if there were a blowout, your skill set would be sorely challenged with any tire, and especially with a car tire.
But that's neither here nor there.
The only reason I respond at all in these kinds of threads is so that the uninformed can at least hear an opposing view. The car tire idea is right up there with shorts, flip flops, half shell helmets, and riding from bar to bar.
People do these things all the time. It may be part of the risk taking mystique of riding a motorcycle.
No minds will be changed until a personal experience forces the lesson.
