Yeah, I know, not another rear tire poll... but the archives don't seem to chock full of tire posts so I'll hang this one out there. Seems like most care for the Dunlops (739, 752 or 606), some like the P12 pirelli's, and one vote for IRC (didn't know they still existed). Anyone care to chime in on what holds up in the rocks?? Yeah, I know, there's plenty of sand as well, but I'd rather error towards squirrelly in the sand than have the knobs chunk off. I had a Dunlop K490 or 495 (I forget...) that lasted about 30 minutes out at Boulder Road once... don't want to do that again!!! Anyway, I'm no racer, just looking for good all around hook-up and good wear characteristics. Thanks for your advice if you post.
