100% True Performance Urethane

True Unbeatable Lasting Performance Urethane
In our labs and most importantly in the streets tested by Spitfire Team riders, Formula Four Performance Urethane lasted longer, withstood more abuse and performed superior to all other wheels. Spitfire Formula Four Urethane was developed to combine all the desired properties of a performance wheel without sacrificing any one attribute at the expense of another. Formula Four's True lasting Performance Urethane comes not from a single benefit, but from a combination of qualities and features that together produce a truly great wheel.

Burn Four-Ever

Longer Lasting- Holds Size and Shape Longer
Formula Four Performance Urethane is unlike any other. Both in the streets and under high-speed stress tests in our lab, Formula Four Wheels retained more material, coned less and kept their original shapes and sizes longer than any other wheel.
Unmatched Abrasion Resistance - Fewer Flat Spots
Formula Four Urethane is made using a 100% pure urethane compound. On the hills, in the streets & parks, and in forced flat spot testing in our lab, Formula Four wheels out-performed and resisted flat spots longer with less wear than all other wheels.
Lasting Speed Everywhere
Formula Four's exclusive combination of High Rebound and Hard Duro produces a faster wheel everywhere. Higher rebound for faster speeds over rough and smooth surfaces. Hard Duro for a harder, faster ride that won't mush out over time.
Smooth Anti-Stick Slide - More Controllable Grip
Formula Four's exclusive anti-stick slide gives a fast/consistent, smooth slide all the way through. Slide with confidence start to finish knowing your wheels won't skip or catch mid-slide. Formula Four gives you the highest level of control and consistent grip you can count on.

  • These wheels are so slick and rideable. Before I used to be afraid of speed wobbles but with the control and speed these wheels have i bomb down hills. Thank you spitfire. Danny Fernandez
  • Having ridden formula 4's for the past year and testing them at every stage, I can comfortably say these wheels will outlast anything out there and are the best feeling urethane,period. Ride the fire! Dave Waite, 35th Ave Skateshop
  • A while back you guys sent me a couple of sets of the prototype models and they were awesome best ones I've rode from you guys! I'm really digging the tablet shape! Andre Davis
  • Formula 4's are sick! These things are like having a 4X4 on these raggedy ass streets! Gabe Soto
  • Thanks to Shane at Bill's Wheels for the recommendation. These wheels are amazing -- fast and smooth ride that slides when you need it, and sticks when you need it. Sorry OJ...I'm off the juice for good. Tim Poneil
  • The Best Riding/sliding/longest lasting wheel i have skated in 20+years.THANK YOU!!! JP, Sunday
  • They slide when you need to slide and grip when you need grip. These wheels can handle anything you throw at them. Been ridding them strong for about 2 months now. Only wheels I will be riding from now on. Great work boys. Kline, Hazard
  • Seeing as that I'm transitioning into my "old-man" phase of skateboarding- more tranny, less flip tricks, the 99's in the new Formula Four Spitfires are perfect for gripping the ground at the Bethlehem Skateplaza and the small mini-ramps I spend most of my time skating now. They feel good cruising through the streets too. . . when I skate to a restaurant to Instagram some food pics. #STEADYEATINGCREW Andy, Homebase
  • Formula Four.... Fast and Smooth, tight through the corners but break loose when needed. A step above. Stormy, Ambush Board Co.
  • Spitfire's new Formula Four Wheels' are the standard that all other wheels should be held to. The Formula Four's skate great, feel amazing and are built to last. Ray Porreca, Fairman's
