In Pic 1, I see most all tires look like this, only brand new tires under 1000 miles do I see have a perfectly round contour. My tires are the stock tires with 3000 miles and they are triangulated as well, one flat for straights and a flat apiece for left and right turn.
As far as surety/security in turns, I had to ease up on the muscle I used to initiate and maintain turns on this bike. I now use a much more gentle touch and I really dont ever notice the tire at all. If you have never dragged a peg, you are WELL within the capabilities of the bike and the stock tire, no worries.
In Pic 2, I think what he is saying about "raised" is the cupping I see. Individual blocks of tread start raising up away from the rest of the tread. I took a pic of my tire like he did, and I have no cupping or raised tread. I believe it's because I use alot of rear brake, to balance the drive force on the rear tire, the tire gets "deformed" accelerating from a stop and then I "deform" it the opposite direction with braking force. I try to use as little front brake as I can get away with because the front tire experiences NO drive force, only braking force. I have never suffered from cupped tires.
