Through Authenticate 
The KidBlock is a micro-knurled tire with two rows of blocks as upper-sidewalls for some bite. We made a large 2.30 like the Kranium and gave the same construction, with a 100psi rating and a 4-ply casing to reduce flats.
Knurled block-shapped non-directional design benefits both acceleration and traction
Knurled centerline in tread pattern allows for continuing, non-interrupted rolling with allows for less rolling resistance
Lightweight casing with folding bead technology for less rotational weight
