Product Information

Full details

The Maxxis Assegai is a professional-grade mountain bike tyre designed for aggressive riders who demand predictable traction across a variety of terrains, from loose loam to wet roots. Developed with input from World Cup champion Greg Minnaar, this tyre excels at providing high-speed confidence and cornering stability, though riders primarily focused on weight-sensitive cross-country racing may find its robust construction heavier than dedicated lightweight alternatives.

FAQs

Can I use liquid sealant with all Maxxis tyres?

No. Only Maxxis Tubeless Ready (TR) tyres are approved for use with liquid sealants. Using sealant in non-TR tyres will void the warranty.

What rim width is best for the Wide Trail (WT) casing?

The WT casing is optimized for rims with an inner width of 35mm, but it is highly effective on any rim between 30mm and 35mm.

What is the difference between 3C MaxxTerra and 3C MaxxGrip?

3C MaxxTerra is an intermediate compound that offers a balance of traction and treadwear, while 3C MaxxGrip is a softer, stickier compound designed for maximum traction in downhill and enduro racing.

Can I use these tyres with inner tubes?

Yes, while they are optimized for tubeless use, they can be used with standard inner tubes if desired.

How often should I replace the tyre?

Replacement intervals depend on mileage and riding style. Inspect the tread for wear and look for any exposed casing threads or significant sidewall damage that compromises structural integrity.

Troubleshooting

Tyre will not hold air after mounting

Check that the tubeless tape on the rim is not damaged and that enough liquid sealant has been added to coat the interior walls.

Tyre beads are difficult to seat on the rim

Ensure the tyre bead is pushed into the center channel of the rim all the way around before inflating, and use an air compressor for a high-volume burst of air.

Excessive sealant leaking through sidewalls

Check for small punctures or sidewall cuts; if persistent, the tyre may need to be retired if the casing damage is significant.

Pros and Cons

Pros

  • Unrivaled traction on almost any trail condition
  • Excellent cornering support at high lean angles
  • Wide range of casing and compound options for customization
  • Durable construction options for aggressive gravity riding
  • Tubeless-ready design reduces flat risks

Cons

  • Heavier than lightweight cross-country tyres
  • Not the fastest rolling option on hard-packed fire roads
  • Complex selection of compounds and casings can be overwhelming for beginners

Setup, Compatibility & Care

To get the most out of your Maxxis Assegai, ensure you are matching the casing to your intended use: use EXO or EXO+ for general trail riding, and step up to DoubleDown or Downhill casings for bike park or enduro racing. Because these tyres are Tubeless Ready, they must be used with a liquid sealant to achieve an airtight seal. When mounting, ensure the rim tape is properly installed and use a floor pump or air compressor to seat the beads. Always check your tyre pressure before every ride, keeping in mind that the maximum inflation pressure is 50 PSI; however, most riders find optimal performance at much lower pressures. Periodically check the sidewalls for signs of abrasion and top off your tubeless sealant every 3-6 months depending on local temperature and usage.
