Odd new kind of tire?



A) Why is the tire yellow? Does yellow withstand heat better? What's
the material? I've heard that adding carbon black to rubber will make
it harder and more wear-resistant.

B) Why does an indoor tire need a folding bead? Do riders on trainers
carry spare tires in their bike bags?

C) Why can't it be used outdoors?

D) Despite my doubts, is this $35 + shipping tire a godsend to riders
who use trainers? Will it outlast four cheap tires?

"At last, a tire designed to stand up to the stresses of an indoor
trainer! Save your expensive tires for the road, and eliminate the
hassle of constantly wearing and changing el-cheapo tires through the
off season. The high performance “cool-running” tread compound and
casing are designed to withstand the extreme heat build between the
tire and roller drum on a trainer. This tire is built to last! “Conti
Yellow” tread and sidewalls. Folding bead. 110 psi recommended, 120
psi max. 280 grams. For indoor trainer use only; do not use outdoors."
