Hey, sorry for the late reply! I haven't logged in for too long!
Part 1:
I ended up purchasing the Procomp MT2 tires & Got the center lugs siped about a month ago. Interestingly, the tires have quieted down a bit as a result. I have a coworker with the same tires who got his siped about 2 years ago. He swears the siping has made them wear longer but I'm not sure about that. I also wonder if different MT's respond differently to siping due to compounds, etc.
