These are Pro-Line's Big Joe 40 Series Tires.

FEATURES: Big Joe offers a 1" wider tread surface, ¾" taller tread, and a
            ¾" larger inner diameter.
          This tire also includes an even more aggressive tread pattern, which
            makes it the new innovation in Monster Truck tires.
          Made from soft M2 compound.
          Carcass design for aggressive traction.
          Exclusively designed for the 40 Series wheels.
          The oversized inner diameter incorporates true, precise handling
            with greater stability.
          Outer sidewall reinforced tread furthers the handling, of the Big
            Joe by limiting the amount of side-to-side roll, which is typically
            seen in Monster Truck tires.
          Pro-Line's firm Impact Foam is also included.
          Ideal for off-road adventures!
          The Big Joe exclusively fits 40 Series wheels for MAXX, Terra
            Crusher, TXT-1, Clodbuster, and Juggernaut II.
