Schwalbe Tacky Chan Gravity Pro Radial Tyre
The Schwalbe Tacky Chan Trail Pro Radial Tyre adapts Schwalbe’s race-winning gravity design into a lighter, faster-rolling package tailored for aggressive trail, all-mountain, and enduro riders. By pairing the revolutionary Radial carcass technology with a weight-optimised trail casing and Apex sidewall reinforcement, this tyre provides the massive mechanical grip of a downhill tyre without the heavy rotational weight penalty on the climbs.
The Tacky Chan Trail Pro Radial is designed for riders who love the speed and precision of World Cup downhill tread patterns but need a tyre that can easily be pedalled on all-day singletrack loops. The Trail Pro casing drops significant weight compared to the heavy-duty Gravity version, making the bike noticeably snappier when accelerating out of turns and lighter when lifting the front wheel over obstacles.
To complement the flexible nature of the Radial construction—where casing plies cross at an obtuse angle to allow the tyre to deform selectively around track debris—Schwalbe updated the Tacky Chan tread layout. It features a revised 2-2 central block arrangement that closes the traditional "dead-zone" transition gap. Combined with supportive, stiff shoulder lugs, the Trail Pro Radial delivers a beautifully predictable, seamless transition from straight-line rolling to hard, dragging cornering angles
Because the radial casing is inherently far more flexible and adaptive than standard tyres, you must change how you manage your tyre pressures. If you set the Tacky Chan Radial to your standard diagonal tyre pressure, it may feel overly soft or vague when pushed hard into a berm.
The Pressure Rule: Most riders find they need to run 1 to 2 PSI higher than their usual baseline to give the radial casing enough pneumatic structure to prevent sidewall folding under heavy G-outs.
The Payoff: Even at a slightly higher pressure, the tyre still achieves a significantly larger footprint and superior compliance over rough track chatter compared to a standard tyre run at lower pressures.
Ideal Placement: The Tacky Chan excels as a hyper-fast, highly precise front and rear combination for dry-to-mixed bike park laps. If you frequently ride deep, greasy winter mud, pairing a classic Magic Mary Radial up front with the Tacky Chan Radial on the rear creates the ultimate year-round high-traction setup.
Because the Trail Pro version sheds weight from the casing, it makes for an incredibly versatile tool when fine-tuning your bike's ride characteristics for varying trail networks:
The Ultimate Trail Setup: Run a Tacky Chan Trail Pro (Addix Ultra Soft) on the front wheel for maximum confidence over wet roots and loose corners, paired with a Tacky Chan Trail Pro (Addix Soft) on the rear to keep rolling resistance low and prolong tread life.
The Full-Power e-MTB Alternative: If you are running this tyre on a full-power e-MTB (like a Santa Cruz Vala or Bullit) and ride exceptionally rocky terrain, it is highly recommended to run the Gravity Pro version on the rear for maximum rock-strike protection, while utilizing this Trail Pro version on the front to keep the front end feeling light and easy to maneuver.
Trail Pro Construction: Optimises the balance between uphill rolling efficiency and downhill puncture safety, utilising a supple 4-layer sidewall profile.
Apex Fabric Reinforcement: Positioned above the bead to improve sidewall stability, defend against snakebites, and dramatically reduce tyre burping under low-pressure trail cornering.
30% Larger Contact Patch: The radial plies allow the tread to contour perfectly over rocks and roots, ensuring more rubber stays glued to the ground at standard pressures.
Flexible Layout Options: Available in both standard Addix Soft (excellent for all-round rolling speed and longevity) and the ultra-sticky Addix Ultra Soft for maximum wet-weather root traction
