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
Wide Trail XC (WT XC)
Maxxis recommends using 2.40″ Wide Trail XC tires on 30mm internal rims. The tires are compatible with rims as narrow as 25mm, but we do not recommend exceeding 30mm wide.
The Wide Trail designation is being phased out, read more about the process here: https://www.maxxis.com/us/news/wide-trail-labeling-discontinued/
