Maxxis Tube Heavy Duty 90/100-16 TR4 (XCS)

Maxxis Tube Heavy Duty 90/100-16 TR4 (XCS) inner tube is engineered for riders who demand reliability, longevity, and confident performance from every mile. Sized specifically for 90/100-16 tires, this heavy‑duty tube delivers stable air retention, reinforced durability, and a trustworthy seal on busy commutes and light adventure rides alike.

Why this tube stands out

Built around XCS constructed fundamentals, the TR4 lineage emphasizes robust stress points, a tougher valve area, and thicker wall design to resist pinch flats and stem damage. The result is a tube that stays inflated longer, handles the bumps of urban roads, and maintains consistent shape under load—so your tire stays properly seated and true to your ride.

Key benefits

• 90/100-16 compatibility: Precisely matched to common 16‑inch tires, ensuring a reliable fit on a wide range of street and light‑off‑road bikes.
• Heavy‑duty wall construction: Thicker walls and reinforced regions provide added puncture resistance and longer service life, especially on rough pavement and curb impacts.
• Durable valve area: Designed to resist leakage and stem damage during inflation and during impact with road hazards.
• Stable air retention: Low-permeability formulation minimizes gradual air loss, helping you maintain optimal tire pressure between rides.
• Consistent seating and fit: Precision manufacturing reduces fitment wobble, promoting even bead seating and predictable handling.

Who benefits most

This tube is ideal for daily commuters, delivery riders, and casual motorcyclists who ride 16‑inch wheels and want a durable inner tube that stands up to busy urban environments, potholes, and variable road surfaces. If you’re restoring an older bike or upgrading aging tires, the Maxxis Heavy Duty tube provides a reliable, long‑lasting option that pairs well with a wide range of 16-inch tubed tires.

Practical use scenarios

• Daily city commuting with frequent stop‑and‑go traffic, where puncture resistance and consistent inflation matter most.
• Delivery or courier rides on mixed surfaces, benefiting from a tube designed to maintain pressure under variable loads.
• Redriving a classic or budget‑friendly 16‑inch setup where you want dependable performance without cornering on worn components.

Installation and care tips

• Ensure tire and rim compatibility with 90/100‑16 sizing before installation.
• Clean the rim surface and inspect for sharp edges or protrusions that could nick the tube during seating.
• Install the tube with a light coat of tire lubricant or soapy water to ease seating, then inflate gradually to the tire’s recommended pressure.
• After initial inflation, check for leaks and recheck pressure after a short ride to confirm a secure seal.

Choose the Maxxis Tube Heavy Duty 90/100-16 TR4 (XCS) for a dependable inner tube that aligns with practical riding needs and the realities of everyday roads.
