Just before CCR, I replaced both tires, which had 11500 miles on them and still had decent tread left. Both were Metzelers. After getting the tires replaced, I didn't ride the bike for a significant distance until trailering up to CCR in GA. On my way to Deals Gap, I was dimayed to find that the front was shaking, as described above, but mostly at 50-60 mph. It felt like an improperly balanced tire, which was confirmed by the dealer upon my return. The tire was rebalanced, and the vibration decreased, but I still felt a shake in the handlebars at around 40-50 mph, which I had not experienced with the original tires. The hop I used to experience between 30 and 40 mph is still there, and I dare not release the handlebars at 40-50 mph or the wobble will be scary. I'm waiting on a new damper, ordered under warranty, and we'll see if the problem is corrected. I thought getting new tires is supposed to give you a better ride, not worse, but I don't think it's directly related to them.
Despite these problems I have described, there is one thing I must say to all who dislike Metzeler tires. I was recently caught in a torrential rain returning from a day ride to Ft. Myers, FL back to Miami on I-75. Visibility was almost nil and the roads were saturated with water. There was no safe place to pull over, so we pressed on. In the 150 mile ride, about 90 miles of it was in this rain. I never experienced any hydroplaning or other pucker events with these tires. Given the mileage I was able to accumulate on the original set, and performance I just described, I would recommend them to anyone who is considering a new set. Just my 2 cents.
