Neither really. If you look in the attached picture of the outer sipes, there is a 1/32 difference between the top inner edge of each outer sipe and the bottom inner edge of each outer sipe (at the first groove). So if you run your hand from front to back across outer edge of tire, you can feel the sharp forward edge of each sipe. If you run your hand from back to front, it feels smooth. So, forward edge of sipe is 1/32 higher than trailing edge. On the first section of tread inside of the first groove, it is smooth all the way around and measurements are consistently the same across the entire width of each tire. The inner sipes do not show this wear pattern.
Tires are wearing quickly as well. In 7k miles, down from 10/32 to 7/32 across all four tires so I can expect to see about 21k out of them at that rate - far too soft. Should note that the two front tires were replaced by Continental because the originals exceeded road force tolerances. The replacements (those on now) gave me an immediate sharp pull to the right which I assume is the result of the a radial bias on one of the tires. Either switching right to left or rotating front to back corrected that problem.
