8200 miles in, the OEM rear tire has about 4/32 left, so I've started the hunt for new one. Due diligence (searching the forums, etc), lead to the conclusion I was hoping for -- Dunlop makes the Elite 4 radial in the correct size. I'm gonna order it now; I'm hearing that some tires have a 6-10 week lead time.(!) I had American Elite's and E4's on my Ultra, and they worked well. The stock Bridgestones worked well and handled well, but I'm disappointed in the mileage. The metzler cruisetech might be an option, but I can't find much feedback on it.
