I haven't bought my TM yet, but should have it in a couple weeks and have been reading lots of threads dealing with tire issues. I gather that I should make sure my tires are balanced, replace the rubber valve stems with metal ones, and consider going to 15 inch tires and getting a tire monitoring system. I do have one additional question. Does Maxxis make a 14 inch tire that will fit TM? I suspect the answer is "no" since I haven't seen it mentioned in any of the threads, but I thought I would ask the question and make sure. I surely do enjoy reading what all of you have to say about your TM's and adventures, and look forward to being a fellow TM owner.
