Motorcycle tires; I'll never understand 'em.
They are really quite easy to understand.
Motorcycle Tires are a marketing scam ... Like motorcycle oil..
They are poorly manufactured with dubious quality control. They are expensive in a way not supported by the "lack of economy of scale" argument. Track specialists don't use the tires we buy, so that argument is moot too.
They are a rip-off, and when the manufacturers "tut-tut" about the safety of a car tire on a bike (it doesn't say "car-tire" on the tire, btw), they need to consider the number of motorcycle tires that regularly cup, shed big bits of rubber, etc, and ask how many CTs do the same thing on a bike.
This is not an argument for CT, simply making the point that we are over-sold a shoddy product while those same companies make cheap tires with twice the materials, that rarely fail.
