Maxxis High Roller II mountain tire 27.5x2.3 - EXO, tubeless-ready dual-compound grip

The MAXXIS High Roller II is a tubeless-ready mountain bike tire with an open, aggressive tread that excels in soft, loose, and muddy conditions.

The High Roller II is designed to dig into loose soil, clear mud, and deliver predictable braking and cornering. Built with a square profile and staggered shoulder knobs, it balances control and a confidence-inspiring feel while the dual-compound rubber optimizes grip without excessive drag. Multiple casing and sidewall options — including EXO reinforcement — make it adaptable to trail, downhill-adjacent, and all-mountain setups.

How does the High Roller II perform on loose and muddy trails?

The open, aggressive tread pattern is engineered to penetrate soft surfaces and eject mud quickly, helping maintain traction when the ground gives way. Large channels between center and shoulder knobs reduce clogging, so the tire keeps biting even as conditions deteriorate.

• Open tread clears debris and mud for sustained traction.
• Staggered shoulder knobs improve sidebite in corners.
• Square profile keeps contact area predictable under load.

What does the dual compound and EXO sidewall provide?

The High Roller II uses two rubber compounds: a softer compound where you need grip and a firmer compound to limit rolling resistance. EXO sidewall material adds cut and abrasion resistance to vulnerable areas without drastically increasing weight.

• Dual compound balances rolling efficiency with edge hold.
• EXO reinforcement protects against rock cuts and scrapes.
• Options let you choose lighter or tougher casings depending on terrain.

Which sizes and setups are available for different riding styles?

This tire comes in common MTB diameters (26", 27.5", 29") and a range of widths such as 2.3" to suit aggressive trail, enduro light-duty, or downhill-adjacent use. Tubeless-ready construction supports lower inflation pressures for better traction and comfort, while DH and DoubleDown (DD) casings increase sidewall strength for high-speed and hard-impact situations.

• Sizes: 26", 27.5" (650b), 29" to match most modern MTBs.
• Widths like 2.3" balance rollover and cornering stability.
• Casing options: EXO for abrasion resistance, DD/DH for heavy-duty protection.

How does the High Roller II affect braking and cornering?

Modified center and shoulder knobs enhance braking bite and provide predictable transitions entering and exiting corners. The tire’s square profile and consistent knob layout deliver a solid, stable feel under varied load and lean angles.

• Center knob design improves traction during braking zones.
• Shoulder knob shape supports aggressive cornering and control.
• Predictable feedback helps riders modulate speed and line choice.

Who is this for: The MAXXIS High Roller II suits riders who spend most of their time on loose, loamy, or wet trails and want a tire that balances aggressive traction with manageable rolling resistance. Choose tubeless, EXO, or tougher DD/DH casings according to whether you prioritize lower weight and suppleness, extra sidewall protection, or maximum durability for technical and high-speed trail riding.
