Hyssk Heavy-Duty 2mm Inner Tube for 3.00/3.50-16 (90/100-16) Rear Tires — TR4 Valve, Puncture-Resistant

Hyssk’s heavy-duty 2mm inner tube is a reinforced, 16-inch TR4-valve tube engineered for rear tires sized 3.00/3.50-16 (90/100-16), offering improved puncture resistance and ride stability for off-road and dirt/pit bikes.

This premium inner tube is built from a thicker rubber compound and manufactured in certified partner factories to raise durability without a major weight penalty. It’s intended for riders who want a more robust replacement tube for 16" rear tires on small motocross, trail, pit, and electric dirt bikes. The tube uses a straight TR4 valve stem and fits common models that run 3.00-16 or 3.50-16 rear tires.

How does the 2mm wall thickness affect durability and puncture resistance?

The increased 2mm thickness delivers stronger resistance to pinch flats and punctures than typical 1.2–1.4mm tubes. Thicker walls also moderate rapid pressure loss from small tears and provide steadier shock absorption across rough terrain.

• 2mm rubber compound for improved puncture resistance
• Reduced pinch-flat risk on rocky or root-strewn trails
• Better shock damping for rough-surface control
• Balances durability with manageable weight

Which bikes and tire sizes is this inner tube compatible with?

This tube is sized for 3.00/3.50-16 (also referenced as 90/100-16) rear tires and uses a TR4 straight valve stem. It’s compatible with many small-displacement motocross, trail, pit, and electric dirt bikes that accept those dimensions.

• Fits 3.00-16 and 3.50-16 rear tire profiles
• Common OEM and aftermarket fits: CRF125/150, CR85, KX140, KLX125, DRZ125, RM85
• Also suitable for similar-sized electric dirt and pit bike rear wheels
• TR4 valve stem for standard pump and inflator compatibility

How does this tube compare in value and service to cheaper alternatives?

Hyssk positions this tube as a value-focused upgrade: modestly higher cost for better materials and longevity. The goal is fewer roadside repairs and longer intervals between replacements, plus customer support during business hours for pre- and post-sale questions.

• Higher-grade raw materials and formulation versus budget tubes
• Designed to last longer under aggressive riding conditions
• Work hours: 08:00–18:00 daily for enquiries and support
• Better long-term value when factoring reduced downtime and replacements

Who is this for? Riders who regularly tackle uneven or off-road surfaces on 16" rear wheels—such as beginner through intermediate motocross and trail riders, pit bike owners, and electric dirt-bike users—will benefit from Hyssk’s heavier 2mm tube. It’s a practical upgrade for anyone who prefers a more robust replacement tube to reduce punctures and improve ride stability, while still using a standard TR4 valve and widely compatible 3.00/3.50-16 sizing.
