The Puncture Protection System is a special fabric placed between a tire's tread and casing to increase resistance to punctures.
Some tires designed for use on rough roads, cobbles and gravel receive a second layer of PPS between the casing and the inner tube we call PPS2.
The cheap nylon is net dipped in a bath of butyl rubber and then calendared (squeezed) between big steel rollers to create the casing that is 50-70% nylon and 30-50% butyl rubber (depending on the thread count.)The higher the thread count the lower the percent butyl rubber. When combined with a butyl tread and vulcanised into a clincher shape the tire bounces down the road. The standard nylon/butyl rubber tire system for cars, trucks, tractors and motorcycles may be attractive when you have a sophisticated suspension system and massive padded seats separating you from road shock. When you have a lightweight, high-performance bicycle where only six to eight kilos of super stiff carbon fiber (wheels, fork, frame, bar, stem, seat post and even saddle shell) highly optimized for efficient power transmission separating you from the road or trail a bouncy (at low pressure) or stiff (at high pressure) or stiff (at high pressure) tire system is painful, exhausting and inefficient.
