I'm going to be replacing the stock tires on my 09 this winter with some Anakees. I would also like to have a couple of new tubes on hand incase I pinch the stock tubes. For my style of riding, I'm not interested in the heavy duty off-road tubes, but rather the lighter versions. I've been liking what I've been reading about the Michelin TR-6 and TR-4, but I'm not clear on the various sizing designations... especially for the rear. For the front I think I need the TR-6, 21" Type A. But I'm having a hard time figuring out the rear. There is a TR-6, 17" Type A, but it's labled for 130/90-17 tires. Then there is a TR-4, 17" Type B listed for 130/80-17, which seems better to me?
Anyone out there using these tubes that might have a suggestion?
Many thanks as always.
