The second and

third lugs

131 and 151 extend to the first and

second sidewall portions

21 and 151, respectively, so that the second and

third lugs

second sidewall portions

21 and 151 when the second and

third lugs

131 and 151 are in contact with the ground, increasing the stability of the off-road tire 00 when in contact with the ground.
