I've started riding my Tonic Fall Guy 24" "mtbmx" on some XC trails. Started solely for training for MX racing but it is getting to be pretty fun. The bike has a K-rad urban style front tire and a old school BMX style rear tire right now. I am trying to figure out what sort of tire combo would be best. Because of the style of bike, I am standing up 100% of the time, I imagine that takes a lot of weight off of the rear and puts it on the front. The trails I ride a handful of downill'ish sections I would guesstimate speeds get up to about 25-30mph. We do not ride when it is wet and at least 85% of the trails are hard pack single track. There are some short steep climbs and lots of roots. Would love to hear ya'll thoughts on the best tire combos for my odd XC ride. Thanks.
