The Origin8 Supercell 26x4.0 folding fat bike tire is designed for street and paved-surface fat-bike riding, combining a wide, fast-rolling tread with channels and siping that help move water away from the contact area.

The tread wraps toward the sidewall to provide predictable grip while turning, including when the tire is operated at low pressure. This exact 26x4.0 version uses a supple dual-compound 120 TPI folding casing, has an ISO 559 diameter, is rated to 20 PSI, and weighs 1375 g | 48.5 oz. The bead and TPI specifications distinguish it from the other Supercell construction.

Key Features

• Street-Style Tread: Wide smooth tread is optimized for rolling on pavement and hard surfaces.
• Water Channels: Large grooves and siping help evacuate water from the tread area.
• Wraparound Profile: Tread continues toward the sidewall for consistent grip while cornering at low pressure.
• 120 TPI Casing: The folding construction is specific to this 26x4.0 model.
• Fat-Bike Size: ISO 559 tire sized 26x4.0 for compatible fat-bike rims and frames.

Benefits

• Reduces the heavy, blocky feel associated with aggressive off-road fat-bike tread on pavement.
• Provides a smoother street-oriented ride while retaining the volume of a 4.0-inch fat tire.
• Supports predictable cornering across the broad tread and sidewall transition.

Best For

• Fat-bike commuting, paved paths, street riding, and hard-surface recreation.
• 26-inch fat-bike wheels with rim and frame clearance for a 26x4.0 tire.
