Maxxis Off Road MX-SI 120/80-19 63M M7334R TT

Take on demanding off-road conditions with confidence using the Maxxis Off Road MX-SI 120/80-19 63M M7334R TT. Built for riders who push beyond the trail, this 19-inch tubetype tire delivers stable steering, predictable grip, and rugged durability when the going gets rough.

Designed for 19-inch wheels in off-road setups, the MX-SI features a tread pattern engineered for traction across dirt, sand, and rocky sections. The legible block arrangement gives your bike quick, precise turn-in and solid feedback at lean, so you can read the ground and adjust mid-corner.

The tire's construction supports aggressive riding without sacrificing longevity: a reinforced carcass resists punctures and sidewall impacts while the optimized tread voids shed mud and debris, maintaining traction when others struggle in slick conditions.

Key benefits

• Trustworthy grip on loose surfaces—the tire bites into dirt, gravel, and soft sand with a stable sense of control.
• Consistent braking and acceleration on wet or muddy tracks thanks to tread geometry that keeps contact patches engaged.
• Robust durability for endurance riding and repeated hard landings after jumps or obstacles.
• Tube-type construction (TT) compatible with traditional inner tubes, making replacement simple for riders who prefer familiar setups.

Who should consider this tire? Riders running 19-inch wheels who demand off-road reliability: enduro competitors, trail riders, and weekend warriors tackling mixed terrain—from dusty loam to slick mud. If you’re upgrading from a dual-sport or street-oriented tire and want enhanced off-road confidence without compromising on stability, MX-SI is a strong match.

Use cases and scenarios

• Enduro loops and timed sections where traction and predictable handling are critical.
• Trail rides in varying terrain—mud, sand, and loose rock—where quick steering response matters.
• Riding on a mix of hard-pack and soft surfaces that demand you stay in control when power is applied.

Maintenance and compatibility tips

• Always pair with appropriate inner tube and rim tape for TT construction; inspect tread wear and replace when needed.
• Follow your bike manufacturer’s recommended tire pressures for weight and terrain to preserve grip and prevent pinch flats.
• After rough terrain, inspect sidewalls for micro-damage to extend tire life and maintain performance.
