NEWBY question: I sponsor a mtn bike club in a remote village in southern Baja. The specialized tire has been recommnended as one that will not easily pucture. We need a superior tire, we have NO access to any bike store for 600 miles .   Is there a good online site to buy these at ?  Which particular 26" specialized armadillo tire should I buy (these will be used for everyday training on hillsides that are VERY ROCKY, not sandy, full of glass shards, cacti thorns. Pls help me. thanks.
