My new used bike came with Kenda Blue groove front and nevegal rears. Short of killing them with fire and putting on maxxis DHF 3C 2.5 ZOMG front and rears, can I do anything to make the blue groove a passable tire? It looks like you can cut the nevergrip to make it a decent tire. Can i cut, sipe, reverse, weld, microwave or sharpie my blue groove to make it perform admirably as a DH/FR tire?
