Just had my 407 rear replaced on my '09 EGC. There was 28,000 kilometres on the 407 and it still had 2/32 tread depth over the wear bars. Can't complain at all about it's milage. Cupping had gotten so bad I couldn't hear the bike any more and the tire caused vibrating. Replaced with an American Elite. I'd forgotten what the feel of the bike was supposed to be. Only have a few hundred clicks on it so far, looking forward to some nice riding. I'll report back once there are a few thousand clicks on the tire.
