Dunlop Geomax MX34 Rear Tire (110/90-19)

The Dunlop Geomax MX34 Rear Tire (size 110/90-19) is an elite soft-to-intermediate motocross rear tire engineered to replace worn stock tires with hole-shot-winning acceleration, aggressive braking bite, and class-leading corner-exit traction. Designed specifically for 250cc and 450cc motocross machines utilizing 19-inch rear wheels, the MX34 builds upon Dunlop's factory racing heritage with an updated tread block pattern that evacuates mud efficiently while generating immense mechanical drive out of soft berms and deep ruts.

The MX34 rear features an optimized block spacing pattern with an 11% taller and 44% wider center knob profile compared to its predecessor. This provides a substantially larger rubber contact patch when applying power in a straight line. Dunlop's patented Progressive Cornering Block Technology (PCBT) on the shoulder knobs enhances lateral grip when railing deep ruts or leaning heavily on flat turns. The casing utilizes Dunlop's Carcass Tension Control System (CTCS), which tunes flex zones across the tire profile to absorb vertical impacts and track chatter, keeping the rear wheel glued to the dirt under heavy throttle applications.

• Tire Size: 110/90-19 (Standard 19" rear motocross rim)
• Terrain Application: Soft, loam, deep sand, muddy ruts, and intermediate soil
• Knob Architecture: 11% taller center blocks with PCBT shoulder knob-in-a-knob design
• Carcass: Optimized multi-ply casing with tuned tension zones
• Mud Evacuation: Widened void ratio for self-cleaning centrifugal mud shedding

### Step-by-Step Installation & Safety Protocols Installation requires heavy-duty tire irons, soapy water lubricant, and a sturdy tire stand. Disassemble the rear wheel, remove the valve core, loosen the rim lock nut, and break the tire bead. Work the tire spoons around the rim circumference to remove the old tire. Inspect the rim tape and rim lock. Coat the beads of the MX34 with bead lubricant. Position the tire matching the directional arrow on the sidewall, insert the heavy-duty tube or bib mousse, push the valve stem through the rim hole, and lever the first bead onto the rim. Carefully spoon the second bead over the wheel lip, ensuring you do not pinch the tube with the tire irons. Inflate to 32 PSI until both beads pop securely onto the rim seat, verify the bead line is concentric around the rim, adjust pressure to 12.0-13.5 PSI, and tighten the rim lock nut to 14-16 Nm.

### Maintenance & Service Life Maintenance consists of regular pressure checks, checking for cracked or missing knobs after rocky motos, and rotating the tire on the rim if directional wear causes rounding of the driving edges.
