Marketing, and the willingness of others to pay the price.


yea, they're immune to that in carland.


There's a couple of noteworthy answers, but they come down to this:

market volume, and you want stickier rubber on bike tires.

The same thing crops up on motorcycle tires: a reasonable mid-priced
sport tire is about US$150-$200, and it goes up from there. and they
don't last very long at all.

On the other hand, the wretched Marathons on my Tercel will slide with
minimal provocation, a tic made less scary only by the fact that cars
are statically stable.

The sacrifice in tread life is an excellent compromise in exchange for
the much better grip of most bike tires. As for the volume costs, when
most bikes on this continent get their tires replaced every two or three
years, then we can talk.

The cheap 13" tire for a Tercel probably ships _inside_ a 20" tire
for a semi.

At the consumer end, the over-riding desire that trumps all other
considerations is that they want the same tire that came on the bike. No


Drat! I hate being just like every other random consumer. Still, I'm
very happy with the tires that came on the bike...

How's that work? How does the rubber know there's kevlar underneath it?

Perhaps the kevlar layer prevents the rubber from flexing as much, reducing
the "scrubbing motion" on the road surface?
