I ride Vermin fronts on both front and rear tires along irrigation canal roads, around lemon groves, along railroad repair access roads, etc. and wouldn't ride anything else because of their puncture resistance. Before switching to Vermins I averaged at least one flat a week because of the high concentration of cactus and tree barbs, stickers, needles and thorns in the sand.

When canal roads are irrigated the mud cakes/sticks to the tires. In wet sand/mud the tires don't have much directional stability.

Vermins are great for dry hard pack sand/dirt use.
