In skateboarding people tend to use angled riser pads to adjust the kingpin angle. As a side effect these riser pads can (ever so slightly) absorb hard shocks and decrease the chance of a wheel-bite (when your wheel comes into contact with the wood of the deck and stops you apruptly). This is not necessary with most longboards as they usually have a higher clearance, or even cutouts at the sports where wheelbites would occur. In street skateboarding the tradeoff is a little different, because the area where wheelbites occur are just next to the area "the pocket" you utilize for nearly all flip tricks. Also taking wood away there would have a negative impact on stability so street skaters would rather live with wheel bites than sacrificing wood area there – or as mentioned use the stiffest pushing you can find, use riser pad, tighten the trucks or similar.
