TYK Industries ATV Inner Tubes 25x8-12 2-Pack — TR6 Metal Valve Stems, Thick Butyl Durability

These are a two-pack of heavy-duty TYK Industries inner tubes sized for 25x8-12 wheels, compatible with 25x9-12 and 25x10-12 ATV/UTV tires and fitted with durable TR6 metal valve stems.

Replace worn or leaking tubes with these reinforced butyl rubber inner tubes from TYK Industries. Engineered for thicker walls and a robust valve seal, they reduce air loss and improve puncture resistance compared with thinner aftermarket tubes. Each tube is factory-inflated and inspected, and the pair includes valve lock nuts so you can safely run lower pressures for better traction when needed.

How do these tubes improve durability compared to standard options?

TYK Industries builds these tubes with a substantially thicker butyl compound that slows air permeation and stands up to impact and pinch punctures. The enhanced construction offers longer service life under typical off-road stresses.

• Up to four times thicker walls than many competitors
• Butyl rubber formulation resists slow leaks and ozone degradation
• Factory-tested inflation to confirm integrity before shipping

Which tire and wheel sizes will these inner tubes fit?

Although labeled 25x8-12, these tubes are sized to fit a variety of tires and wheel diameters commonly used on ATVs and some utility vehicles. They also match several 11-inch wheel tire sizes, making them versatile for multiple applications.

• Main fit: 25x8-12 tires
• Also compatible: 25x9-12 and 25x10-12
• Additional fits: several 11" wheel sizes such as 23x8R11, 23.5x8R11, 23x9R11, 23x10R11

What makes the TR6 metal valve stem and seal better for off-road use?

The TR6 metal valve is vulcanized into the tube to create a reliable seal that resists pulling and leakage. A threaded lock nut is included to secure the valve base, helping maintain pressure when operating at low psi for improved traction.

• Vulcanized valve seat provides a strong, permanent bond
• Metal TR6 stem resists bending and valve failure
• Valve lock nut lets you set and secure lowered pressures safely

What warranty and quality checks come with each purchase?

TYK Industries backs these inner tubes with a three-year warranty against manufacturing defects, and each tube is individually inflated and inspected at the factory to help ensure a smooth installation on arrival.

• Three-year coverage for workmanship and materials
• Factory test inflation verifies basic integrity prior to shipping
• Sold as a convenient two-pack for paired wheel replacements

Who is this for? These TYK Industries 25x8-12 inner tubes are ideal for ATV and UTV owners who want a more rugged, longer-lasting replacement than thin stock tubes—especially riders who value reduced air loss, better puncture resistance, and the option to run lower pressures for traction. They also suit owners of trailers, garden wagons, golf carts, and quad bikes compatible with the listed sizes who need dependable, service-ready tubes backed by a warranty.
