According to Conti:

GP Attack 4plies/ 370 tpi

GP Force 5 plies/ 430 tpi

I know a lot of other factors go into the the ride quality, durability (or lack thereof) and performance, but these tires have pretty low TPI - 92.5 TPI front and 86 for the rear! Someone correct me if I am wrong, but I am going to call BS on Continental. They make cheap casing with low TPI, fold it over 4 or 5 times to get these "amazingly" high TPI numbers, then reduce the thickness of the rubber to keep the total weight down:

Veloflex Pave's have 300-350 TPI with a lot less weight. Many low end tires have 127 TPI. Am I wrong? Do all tire companies multiply the TPI of the fabric x the number of plies?
