Q: How should these load wheels be stored when not in use?
A: Store the WW PM-5F wheels in a clean, dry warehouse location away from direct sunlight and moisture. Keep them on a flat surface or mounted to prevent flat-spotting. Avoid extreme temperatures and chemical exposure to preserve polyurethane tread integrity.
