I'm the proud new owner of a 20" YBB I picked up at Sunshine Bicycle Center. I'd like to run a set of Continental Mountain King UST tires on my 29 Crossmax wheels. I have the 26" version of these tires on my Ibis and love them. Can I run the 2.4's or do I need to stick with the 2.2's? I threw a pair of Nevegal 2.2's on there for my inaugural driveway ride and they're pretty tight. Nevegal's run big and the Mountain King's run small but I'd like to hear it from someone who's tried it. I'm open to other tire choices as well. I'll be riding it mostly in Vermont (wet/roots) and am more of an all-mountain guy than a racer. Thanks.
