I had not bought tires for years and have been net with extreme sticker shock! I've also had great difficulty getting specific info on the following brands: Michelin Trial Winner in the X11 and X-Lite Series (all made in Spain?) Dunlop 803 (Made In?) IRC Trial Winner TR-11 (Japan?) Mitas ET-01 (Czech Rebublic - the old Barum people) Vee Rubber VRM 021 (Thailand) Very helpful would be more specific and complete info from your collective wisdom in one thread that would go beyond comments like, "IRC is all we use around here", and "Vee Rubber are the tits!" That doesn't answer why, or help much with a buying decision. I incline toward the Michelin X11 on the rear and maybe the Michelin X-Lite on the front, for purely performance-durability reasons, but please challenge my assumptions and contribute to dense info in this one thread: Your specific terrain types, class and level of throttle aggression Tire brands you have used When and where bought, tire and shipping costs Specific problems - where on the tire and what Wear life of knobs and carcass (durability) Your specific summary recommendations in rank order by brand/model (best at top) or by terrain type Other comments: Flip your tires? Accurate weights of each brand and model tire you buy before mounting! Etc. Thanks so much for your expert contributions!
