Spitfire is the World's #1 urethane for a reason... Performance.
All Spitfire wheels are hand poured, shaped and specifically engineered in San Francisco CA. USA.

Only the most advanced formulas and compounds are used for all wheels. Manufactured using a 100% pure urethane compound, Formula Four wheels out-performed and resisted flat spots longer with less wear than all other wheels tested. The Spitfire urethane compound gives higher rebound for faster speeds over rough and smooth surfaces with a hard durometer for a smoother, faster ride that won't fade over time. Designed with an exclusive anti-stick formula that gives a fast/consistent, smooth slide all the way through.
Spitfire achieves the highest levels of tolerance and true speed.
Often imitated and never duplicated.
Spitfire wheels are the standard by which all skateboard wheels are measured.
