The tire was bald and actually went flat! I'm not hard on the bike at all - never spin the tire - although I thought I lost my "need for speed" a long time ago 'til I got this bike! Lol!! Dealer picked up the bike and installed the new rear tire - same as original - The Dunlop 200mm. I thought I shoulda got more outta the tire myself, but the dealer told me, here we go, "That's normal" for this particular tire - usually about 5,000 mi. I had my 5,000 mi. service done since they had the bike. Total bill was $512!! Hmmm!! guess I gotta start a separate savings account just to own this thing! Anyway, after I got the bike back, it was fine for the last 3 weeks 'til the other day when my Lady and I went for a ride. Started moaning right off the bat. I ride daily since the bike is my primary mode of transportation. Thought maybe it was from riding 2 up, but it still moans with just me as well (she spends about a third of riding time on the bike anyway). Had the bike out yesterday with the 2 of us. It's still moaning, but does seem to have dissipated somewhat.
