I have a pair of Michelin Pilot Road 2s, installed by the dealer. I don't know if they are 'G' rated. They have 7,000 miles now, and they will clearly go much further.
About 5,000 miles is urban - 50% city stop 'n' go, 50% freeway. The remaining 2,000 miles is long distance riding with 50% highway, 50% twisties and sweepers. In general, I am a gentle rider, but I am quite willing to peg the needle at a freeway onramp, for example. The stop 'n' go riding must be taking its toll on the tires, too.
Obviously you are not doing Sturgis-style burnouts. I am hard-pressed to guess why you haven't gotten similar results. De-icing chemicals? Road grooves? Lots of gravel? Abnormally heavy loads?
In case it helps, I got 6,600 miles on the Bridgestone BT020s that came with the bike. At that point, I took a nail, but the rear tire was at the wear bars, and the front tire was somewhat scalloped.
