Spitfire Sapphire Radial Wheel

Soft Spitfire Sapphire Radials built to cruise rough streets with clear style and Formula Four performance under the hood.

Spitfire Sapphire Radial Wheels are Spitfire’s 90a “soft cruiser” line, using a clear 90DU outer riding surface bonded to a harder 101DU Formula Four inner core. That dual‑duro build gives you a plush, grippy roll on rough asphalt and crusty footpaths while the inner core keeps things feeling snappy, fast and resistant to flat spots like a regular Spitfire street wheel. All Sapphires use the Radial shape with a wide contact patch and round edges for stability, control and predictable slides when you want to loosen them up. Available in sizes from around 53–58 mm, they’re dialled for cruising, filming missions and everyday pushing when you want comfort without going full longboard wheel.

• 90DU clear outer layer: Softer clear urethane smooths out rough pavement and adds grip, ideal for crusty streets and ditches.
• 101DU Formula Four core: Hard inner core maintains speed, crisp response and strong flat‑spot resistance.
• Radial shape: Round‑edge, wide contact patch design for control, speed and a responsive, predictable slide.
• Cruiser/filmer focus: Tuned for smooth rolling, comfort and stability when pushing long distances or filming lines.
• Multiple size options: Typically offered in 53, 54, 56 and 58 mm so you can match your deck and how soft you want the ride.
• Sold as a 4‑pack: Each set comes as four wheels ready to drop bearings in and bolt straight onto your trucks.
