When I bought my 2012 Spyder in June of 2015, it had 8,000 miles on it, and I pointed out to seller that the rear tire was almost worn out. He had not noticed and was quite surprised. As I was already planning a trip in August, I came on this sight and learned about tires. I was good friends with the manager of the local tire store, so I asked him for a great tire and he sold me one with an 80,000 mile warranty on it. It lasted 40,000 miles. I next went to a Pirelli recommended by Blueknight911(RIP). That tire is is still on the Spyder, tho it's now due to be changed. It has about 35,000 miles on it. To say I am happy with my aftermarket tires would be an understatement. As an added note, it does annoy me that even people who know better keep referring to "going darkside" when putting anything other than a Kenda on our machines. There is no such thing in the Spyder World. It`s like saying you are "going darkside" on your car.
