I went on a 2700 mile trip and took my Spyder into the stealership to have the vibration problem looked at, and was told my rear tire was down to the wear bars. I said WHAT?! The bike only has 3100 miles on it! How could I need a new back tire?! I bought just over a month ago, and was trying to get 600 miles on it before I left for my trip. The guy at the dealer said they were pretty bad tires from the factory and a lot of riders are going to other tires. What I would like to know is what are some of you guys changing to, and how many miles are you getting out of them?
