RUHUO 90/100-16 Dirt Bike Inner Tubes 2-Set — Thickened Butyl, TR4 Lockable Valve & Repair Kit

RUHUO 2Sets 90/100-16 inner tubes are thickened butyl replacement tubes for 16-inch dirt bike tires (3.00/3.25/3.50-16) supplied with TR4 lockable valve stems and a basic roadside repair kit.

When a trail day leaves you with a puncture or you want a more durable spare for off-road use, these RUHUO inner tubes offer a robust, budget-friendly option. Each set contains two heavy-duty butyl tubes sized to fit 16" rims with a 3.00–3.50" inflated width range, plus practical accessories to get you rolling again. The TR4 straight valve stem and locking nut aim to keep the tube seated on the rim, while the thicker butyl formulation improves airtightness and tear resistance compared with thinner, conventional tubes.

How does the thicker butyl rubber affect performance on rough trails?

Thickened butyl rubber delivers stronger resistance to punctures and reduces slow leaks versus lightweight natural rubber tubes. You’ll notice better pressure retention over long rides and fewer roadside fixes.

• Enhanced airtightness to maintain tire pressure longer
• Greater flexibility to absorb impacts without splitting
• Improved durability against thorns and rough terrain

Will the TR4 lockable valve stem fit my motorcycle rim and prevent tube slippage?

The TR4 straight valve stem included is a common size for 16" motorcycle tubes intended for 3.25–3.50" widths and works with most rims of this spec. The alloy stem and locking nut secure the tube to the rim to reduce movement that can lead to tearing.

• Universal TR4 straight valve for many 16" rims
• Alloy construction resists rust and oxidation
• Locking nut helps stabilize the tube on the wheel
