Standard - Your classic wheel shape, it's not built to excel in specific scenarios like a narrow or wide wheel, but it's appropriate for most situations. If you're new to skating this is where you want to start.
Treaded - Treaded wheels provide improved grip and traction on smooth surfaces.
83b - Most urethane skate wheel durometers (hardness of a wheel) range from 75a-101a, the higher the number the harder the wheel.
While most industry skate wheels use the standard “a” scale when determining wheel hardness, the “b” scale is 20 points lower than your typical “a” scale, meaning the hardness of an 83b wheel would in turn equal a 103a in hardness which would be beyond the limitations of the “a” scale.
