Maxxis Assegai mountain bike tire, Black, 27.5x2.50WT - 3CT, EXO+, E25, high-traction 3C MaxxTerra

Maxxis Assegai 27.5x2.50WT with 3C MaxxTerra and EXO+ is a high-traction, wide-trail mountain bike tire designed for aggressive trail and light e-bike use.

The Assegai is Greg Minnaar’s signature tread rebuilt for modern rims and varied terrain: its broad contact patch and chunky knobs deliver predictable grip at extreme lean angles while the 3C MaxxTerra compound balances traction, rolling efficiency and durability. Built with EXO+ sidewall protection and an E25 rating, this 27.5x2.50WT model fits wider rims and supports light-assist eMTBs up to 16.1 mph, making it a versatile choice for trail riders who want confidence on roots, rocks and loose surfaces.

How does the Assegai improve traction on steep or loose trails?

The Assegai’s tread layout puts aggressive, ramped knobs across the shoulder and central zone to bite into soft and broken ground. Knob shape and spacing are tuned to hold edges through deep lean and to clear mud consistently.

• Wide-trail profile increases the usable contact area on modern rims.
• Chunky shoulder knobs lock in cornering traction at angle.
• Central tread offers a balance of rolling speed and braking control.

What benefits does the 3C MaxxTerra compound bring?

3C MaxxTerra is a three-layer rubber blend positioned between MaxxSpeed and MaxxGrip for a pragmatic mix of grip, wear resistance and lower rolling resistance. It’s optimized for trail use where riders need lasting tread life without giving up traction when the surface gets loose.

• Multi-compound design for improved contact and resilience.
• More traction than harder compounds, less drag than the softest options.
• Engineered to last for mixed-condition trail riding.

Why choose EXO+ and what does the E25 rating mean?

EXO+ adds a slim butyl insert around the bead on top of the cut- and abrasion-resistant EXO sidewall, giving extra protection where rims and tire meet—useful on rocky, root-laced trails and for lighter e-bikes. E25 denotes suitability for pedelecs with assistance up to 16.1 MPH, so the tire construction meets the loads and speeds of many light-assist systems.

• EXO+ bead insert increases sidewall robustness without heavy weight penalty.
• Improved puncture and rim-protection for technical lines.
• E25 certified for light-duty e-bike compatibility up to 16.1 MPH.

Which rims and bike setups suit the 27.5x2.50 WT Assegai?

Wide Trail (WT) tuning matches the tire’s profile to modern wider rims for an improved shape and knob support. The 27.5x2.50 size works best on rims with internal widths around 30mm but remains compatible on a broader range of 19mm–35mm internal widths depending on handling preference.

• Optimized for ~30mm internal rims for ideal sidewall and knob performance.
• Fits a variety of trail and enduro bikes in 27.5 wheel standard.
• Works as a front or rear option depending on rider’s traction needs.

Who this tire is for: Riders who want a confident, modern trail tire that balances aggressive grip with long-term durability—especially those running wide rims or using light-assist e-bikes. If you push hard on technical descents, favor a predictable edge at deep lean angles, and need extra sidewall protection without excessive weight, the Maxxis Assegai 27.5x2.50WT 3C MaxxTerra EXO+ E25 is a practical, high-performance choice.
