A: You can get a very similar tire in a knobby. Under our Build Your Own Tire Assembly - Small Tire, select the 145/70-6 Carlisle Knobby Tire, 6" Rim with a 1" Bore, and have it Mounted. This combination is slightly taller & wider the 4.10, but does have the knobby tire. Answer provided by:  BMI Karts (5/17/2016)
