Keizer Wheels Sponsors Proving Grounds at 2025 Sand Sports Super Show
COSTA MESA, Calif. (Aug. 21, 2025) — The Sand Sports Super Show today announced that Keizer Wheels will serve as the presenting sponsor of the Proving Grounds, one of the event’s most anticipated live-action attractions.
In partnership with HammerKing Productions, the Proving Grounds brings spectators up close to the raw power and skill of off-road racing. The showcase features purpose-built race machines — including the King of the Hammers Ultra4 Class, UTVs and pre- runners — in a series of high-intensity demos designed to push vehicles and drivers to their limits.
“Keizer Wheels is known throughout the industry for building products that thrive in the toughest environments,” said Tracy Feinsilver, SVP Motorsports & Outdoor Group, Bonnier LLC. “Their commitment to performance and innovation mirrors exactly what the Proving Grounds is all about, and we’re proud to have them on board as this year’s sponsor.”
