Well Itry not to be condesending, BUT...
I recently rode with some liter bike guys (really good riders each one) wearing the latest in DOT race tires and found they had no idea that those tires were crap on the street. We were tearing up some Ozark highways and they were spinning everywhere unable to get them up to operating temperature. They were take offs of their race bikes and had been heat cycled to hell and back and were refusing to heat up even at lower psi on the cool fall highways.
I didn't say anything to them, just smiled smuggly as my 5000 mile old BT021 touring rubber with 36 psi in the rear hooked up and had great traction...I would have hated to have this 180 v 190 or 120/60 v. 120/70 conversation with them.
