Maxxis Off Road MX-SI 70/100-17 40M M7334F TT is built for riders who push the limits on dirt, sand, mud, and rocky trails. With 17-inch rims in mind and a traditional Tube-Type (TT) construction, this MX-SI tire delivers dependable performance when every corner, line, and obstacle counts.

• Off-road focus with targeted traction: The MX-SI tread pattern is designed to bite into loose surfaces and maintain grip through uneven terrain, giving you confidence on mud, sand, and rocky sections.
• 17-inch compatibility: Optimized for modern 17" rims, delivering precise steering response and a stable feel as you navigate technical sections.
• Tube-Type reliability: TT construction suits riders who use inner tubes, offering simple mounting and consistent sealing under tough riding conditions.
• Durable, long-wearing performance: A rugged carcass and compound balance grip with durability, helping you get more rides out of each tire without sacrificing traction.
• Clear load and speed labeling: Marked 70/100-17 with 40M, so you know the tire’s intended load capacity and performance envelope at a glance.

Designed for motocross, enduro, and trail riders who prefer a 17" rear/front setup, the MX-SI stands up to demanding sessions where pavement isn’t an option. It excels in mixed-terrain days—think forest trails after rain, desert washes, or technical man-made courses—where a dependable tire can make the difference between a clean run and a slow crawl.

Who should consider this tire:

• Riders with 17" wheels seeking a purpose-built off-road tire for recreational or competitive use
• Enduro and motocross enthusiasts looking for consistent bite in loose conditions
• Anyone running a tubed setup who wants predictable, reliable performance on challenging terrain

Practical tips for getting the most from the MX-SI: inspect the tread for irregular wear and embedded debris after rides, ensure correct tube-type mounting and alignment, and follow your bike manufacturer’s guidance for tire pressure to balance grip and durability. For best results, use this tire as part of a matched front-rear setup on off-road-focused builds, and reserve it for dirt-oriented sessions to maximize traction and longevity.
