maxxis creepy crawlers all the way, very cheap and very gooooood. Creepy Crawlers last me about 4 months. riding on average 12 hours a week every week. as for the echo tyres, i have one at the moment on the rear and to be honest i dont like it atall, 1. The echo hasn't lasted any longer than the maxxis CC. 2. noticable less grip with the echo. 3. sidewalls are to stiff for me unless i run it with very low psi.
