We've found Regul Brand tires to be one of the best selections for both on the road, and off. Quiet, long wearing operation on the highway and excellent snow and rain traction are synonymous with the Reguls. Average wear on the highway typically puts the mud terrains past 45,000 miles. Off road traction is legendary, with low tire pressures allowable down to 2-3 psi, while still retaining tire shape conformity and rim bead adhesion.
