Product Information

Full details

The Dunlop Geomax MX 12 is a professional-grade motocross tire specifically engineered for motocross riders who frequently tackle deep sand and muddy tracks. It offers championship-level traction and enhanced slide control, making it an essential upgrade for competitive racing in loose, shifting terrain; however, it is a specialized tool that performs poorly on hard-pack surfaces and will wear prematurely if used on inappropriate terrain.

FAQs

Can I use the MX 12 on hard-pack dirt?

No, the MX 12 is specifically designed for sand and mud. It will perform poorly and wear out very quickly on hard-pack tracks.

Is this a front or rear tire?

The models listed are designated as rear wheels.

How does it compare to the MX 11?

The MX 12 is the advanced successor to the MX 11, featuring refined pattern optimization for better slide control and shock absorption.

Do I need a special tube for this tire?

Use a high-quality heavy-duty tube compatible with the specific tire size to prevent punctures while riding in rough, rutted conditions.

Is this tire street legal?

No, the Geomax MX 12 is designed strictly for off-road motocross racing and is not DOT approved for street use.

Troubleshooting

Tire is spinning on loose sand

Check your tire pressure; slightly lowering the pressure can increase the footprint in extremely soft sand.

Accelerated tread wear

Confirm that the riding surface matches the tire's intended use. Operating on hard-pack or rocky tracks will damage the specialized tread blocks quickly.

Pros and Cons

Pros

  • Unmatched traction in deep sand and mud
  • Predictable slide control for cornering
  • Excellent shock absorption over rough terrain
  • Professional-level performance for racing

Cons

  • Not suitable for hard-pack surfaces
  • High wear rate if used on rocky or dry terrain
  • Specific to soft, loose surface conditions only

Setup, Compatibility & Care

The Geomax MX 12 is available in various sizes, including 10, 12, 14, 16, and 19-inch rear wheel configurations to fit a wide range of motocross bikes. Always verify your specific bike’s rear rim diameter and tire width requirements before installation. For optimal longevity, ensure the tire pressure is adjusted according to the specific softness of the sand track. After use in mud, wash the tire thoroughly to prevent debris buildup and inspect the tread blocks for signs of premature tearing, which can occur if the bike hits hidden hard-pack sections or rocks during a race.
