The Spitfire Wheels Formula Four Conical Yellow 56mm/99d are designed for skaters who want maximum control, durability, and performance—especially when riding mixed terrain like SoCal’s gritty ledges and rough street spots. With a Conical shape, these wheels offer maximum width (35.5mm) and a riding surface of 23mm, giving you serious contact with the ground for locked-in slides, extra stability on landings, and smooth cruising through cracks and crust.
Poured with Spitfire’s iconic Formula Four urethane, the 99a durometer balances slide and grip while resisting flatspots and wearing evenly. Whether you're blasting transition, charging banks, or slapping curbs, these wheels are built to take the abuse. The cutaway conical profile offers a solid, controllable shape with a wider riding patch for that “locked-on” feeling when you need it most.
Spitfire’s Formula Four wheels are trusted globally and still hold it down in every corner of the culture. Backed by years of testing and feedback from pro skaters and legends, the Conical Full is a favorite for its mix of speed, grip, and slide control. Spitfire’s role in skateboarding—dating back to 1987—is as deep as it gets. From the early days of EMB to today’s most stacked crews, their wheels have rolled through every generation and every kind of session.
Locally, these 56mm burners make sense. They’re wide and grippy enough for the sandpaper schoolyards of East L.A., yet hard and fast for hitting the buttery ledges at Culver or skateparks like South Pasadena. That 23mm contact patch holds up on the roughest Monrovia alley or in the slick bowls behind Claremont’s train station.
