Albert Radial Tire - 27.5" Trail Pro, Addix Soft, E-50

Schwalbe Albert Radial Tire in 27.5" is a trail-focused mountain bike tire built around a Radial carcass that’s designed to increase the contact patch and better conform to uneven ground. For riders, that translates to a tire that tracks with more consistency through chatter and small impacts, with a calmer, more controlled feel—especially when pushing hard on hard-packed trails and mixed conditions.

The tread uses a closed, round profile and a knob layout tuned for continuous grip, pairing predictable steering with the added damping and ground-hugging behavior that radial construction is intended to deliver. Finished with Addix Soft rubber and an E-50 e-bike rating, it’s a strong fit for trail bikes and higher-load e-MTB use where traction and composure matter.

• Radial carcass construction - Designed for a larger, more terrain-conforming contact patch for added grip, comfort, and control
• Increased contact area by design - Radial casing is engineered to deliver approximately 30% more contact area at the same pressure (and still about 15% more even with a 50% pressure increase)
• Closed, round tread profile - Promotes predictable handling and stability, especially on hard-packed trail surfaces
• Optimized knob pattern - Many lugs support continuous traction and durability under sustained trail use
• Addix Soft compound - Prioritizes confident grip for aggressive trail riding where traction is the limiting factor
• E-50 rating - Intended for the added speed and load demands of higher-speed e-bike applications
