Maxxis Aggressor mountain bike rear tire, 27.5x2.50WT – Dual‑compound, EXO, E25 tubeless-ready

The Maxxis Aggressor is a tubeless-ready rear mountain bike tire built for fast, hard-packed and rocky trails, offering a dual-compound tread, EXO sidewall protection, and an E25 e-bike rating in a 27.5x2.50WT size.

Built to serve as a durable, high-speed rear tire, the Aggressor pairs well with aggressive front tires like the Minion DHF or Assegai to create a balanced handling setup. The 27.5x2.50WT version uses a Wide Trail profile tuned for modern rims, a dual-compound rubber layout for a compromise between speed and traction, and EXO carcass reinforcement for improved resistance to cuts and abrasion. It's tubeless-compatible and carries an E25 rating for light e-bike assistance.

How does the Aggressor balance rolling speed with cornering grip?

The tire employs two rubber compounds across the tread: a firmer center section for reduced rolling resistance and a softer shoulder compound to increase bite when leaning into turns. This targeted distribution helps maintain forward speed while still giving predictable lateral traction under load.

• Dual-compound tread: firmer center, softer shoulders
• Low-profile center knobs for efficient rolling
• Softer side knobs for improved cornering stability

What protection features prevent flats and sidewall damage?

EXO sidewall reinforcement adds a dense, abrasion-resistant fabric layer to the tire’s shoulder area, helping guard against cuts from sharp rocks and roots. Combined with a sturdy casing option (DD available on select sizes), the Aggressor is built to withstand rough trail surfaces that target sidewall vulnerability.

• EXO fabric on sidewalls for cut resistance
• Available Double Down (DD) casing for extra puncture protection
• Tubeless-ready bead and casing for lower pressures and fewer pinch flats

Is this tire compatible with my modern rim and e-bike setup?

The 27.5x2.50WT designation means the tread and profile are optimized for wider rims (WT = Wide Trail), delivering the intended contact patch and handling on rims roughly 19–35mm internal width. The Aggressor also carries an E25 rating, making it approved for light-assist e-bikes up to 25 km/h (16.1 mph).

• WT profile tuned for wider modern rims (ideal around 30mm internal)
• E25 rating suitable for light-duty e-bike use up to 16.1 mph
• Tubeless-ready for safe low-pressure riding

How should I use the Aggressor on my bike for best performance?

The Aggressor excels as a rear-specific tire where high-speed tracking, predictable braking, and durable sidewall support matter most. Pair it with a more aggressive front tread for improved front-end bite, and run tubeless at pressure appropriate to rider weight and terrain to maximize grip and puncture resistance.

• Designed primarily as a rear tire for stability and rolling efficiency
• Pair with an aggressive front tire for optimal control
• Use tubeless setup and adjust pressure for rider weight and trail conditions

Who is this for: The Maxxis Aggressor 27.5x2.50WT EXO E25 is aimed at trail riders and e-MTB riders seeking a fast-rolling, durable rear tire for hard-packed, rocky singletrack. Choose it if you want a rear tire that emphasizes speed and sidewall protection while still offering dependable cornering traction when leaned over. If you frequently ride on rough terrain, run a wider rim, or operate a light-assist e-bike, this tire is a practical match.
