On the bigger tires, you can go conventional.
I know many have done it, but I'm not a fan of running XC non-UST tires in a Stan's tubeless setup--bead separation, burping, and punctures that Stan's won't seal. However, we've had bombproof results running 2.2 and bigger conventional tires even in the rocks, cactus, and mesquite we have around here--and that's even on long travel, big hit bikes. For nearly or sometimes less than the same weight, you can run 2.3-2.5 conventional tires instead of 2.1-2.2 UST tires. For example we've run 2.5 Weirwolfs (725g) and 2.5 Mich. Hot S (840) with no problems. UST tires in this size usually run from 900-1200g. These larger conventional tires have thicker, stronger carcasses. Not all larger conventional tires are necessarily good tubeless candidates, however. Some of the Gazzys have very thin sidewalls for example. The Mich. Hot S (the red ones) have the same tread pattern and size of the 2.5 DH Comp 24 (1250g). I like running a 2.5 on the front and a 2.2 in the rear. These are very durable tires with a strong carcass and fast rolling qualities that still get great traction.YetiTrailRider said:
