Maxxis Tube 3.00/3.25-12 TR4 (XCS) is a purpose-built inner tube for compact wheels. It fits tires in the 3.00–3.25 inch width on 12-inch rims and uses a TR4 valve stem for dependable inflation and sealing.

Reliable performance where you ride

With a durable butyl rubber construction, this tube minimizes air loss between inflations and provides consistent pressure across a wide range of temperatures and operating conditions. The TR4 valve is designed for robust seating on standard air pumps and valve accessories, helping you get back on the road quickly after a flat.

• Fit and compatibility: specifically sized for 3.00/3.25-12 tires on 12" wheels. Works on minibikes, scooter platforms, go-karts, and light utility vehicles that use tubed tires.
• Durable construction: reinforced sidewalls and valve patching reduce the risk of leaks at the stem and along the tube.
• Installation-friendly: flexible tube that inflates evenly, making seating bead easier and reducing pinching when mounting on rims with standard rim tapes.
• Maintenance and longevity: holds air consistently and resists aging with exposure to heat, sunlight, and regular use.

Smart use cases

Examples: replace worn tubes on a 12" minibike or scooter, restore reliability to a small go-kart, or refresh lawn- and garden-equipment with 12" wheels. When you need predictable traction and dependable flats protection, this Maxxis tube delivers.

Care and tips

• Check inflation before rides and adjust to the recommended pressure for your tire and load.
