Had such a bad experience with 3 2.6/exo+/3c maxx terra DHF&DHRII's over the past 500 miles that I had to try something wildly different. Blew through two rear tires for no reason. Compound was legitimately as hard as their single-compound cheapo tires - that and they blew up to a 2.5. Sidewalls were good, didn't leak sealant, mounted up easily and those were the only redeeming qualities. Never had a real problem with maxxis tires before those 2.6's. Adding on half a pound and getting up to a true 2.6.
