Technology

MaxxSpeed

The new MaxxSpeed (2023) is our top-shelf rubber compound for XC racing. It’s a high-silica content compound which reduces rolling resistance while also enhancing wet traction. Compared to the previous 3C MaxxSpeed, the new compound has approximately 25% less rolling resistance in a lab setting (using the same tread pattern, construction, and tire pressure). In a real world setting, our testing shows the new compound can save up to a minute over the course of a 90-minute race.

EXO

EXO is a cut- and abrasion-resistant material added to the sidewalls of many Maxxis mountain bike and gravel tires. This densely woven fabric is lightweight and highly flexible, ensuring that the performance of the tire remains unaffected. Choose EXO Protection for enhanced durability for gravel, XC, and light-duty trail riding.

Tubeless Ready

Maxxis Tubeless Ready (TR) tires offer better traction, lower rolling resistance, and fewer flats by eliminating the inner tube. Run lower pressures for improved grip and control. Look for the “TR” marking on the sidewall.

Installation Note: Must be used with tubeless-compatible rims and liquid sealant to maintain air pressure and seal small punctures. Check and refresh sealant regularly as it dries over time.

Important: Use sealant only in tubeless road, tubular, or tubeless ready tires. Using it in other Maxxis models voids the warranty.
