A tire inner tube is an inflatable ring that forms the interior of some pneumatic tires. The tube is inflated with a valve stem, and fits inside of the casing of the tire. The inflated inner tube provides structural support and suspension, while the outer tire provides grip and protects the more fragile tube. They are widely used in bicycles and are also used in many motorcycles and heavy road vehicles such as trucks and buses. They are now less common in other wheeled vehicles because of the benefits of having no tube, such as the ability to operate at low pressure and at high pressure (unlike a tube tire, which would pinch at low pressure and burst at high pressure), without going flat. Large inner rings also make effective flotation devices and are widely used in the leisure activity of tubing.

Truck tube is the tube designed for truck. The truck tube provides cooler running for long haul, high speed service. It helps provide longer tread wear, allowing for a higher TMPH rating for improved overall performance. And it helps provide traction both forward and backward.

Car tube is the tube designed for car. Tube is a circular and ring-like part of a vehicle which comes in contact with ground. Tubes are fitted on rims and are filled with compressed air. Since their invention, natural rubber is the most widely used material in manufacturing of tubes.

OTR tubes are the short name of off the road tube. OTR tube mainly used for the giant truck vehicles in mine area. Aggressive tread pattern offers long even tread wear, a cooler running design and improved traction, which is specifically designed for high speed service. The radial construction also allows for a softer ride, improved treadwear and better fuel economy.

A bicycle tube is a unit designed as a bicycle accessory. It is usually made from durable rubber materials such as butyl rubber compound for enhanced durability and the highest level of strength known to man. These bike tubes help protect your tires from getting flat or developing punctures.

Motorcycle tubes are manufactured from natural rubber and are fitted with a centrally position straight metal valve.

The tire flap is an integral part of a tube type truck tire and protects the tube from chafing, heat, and protrusion from the valve hole. Rex-Hide became the only independent producer of truck tire flaps in the United States and at the time marketed its product strictly to tire manufacturers.

Snow tubes are basically oversized inner tubes with a round cut-out section in the center. They are often referred to as "donuts" because of their shape. Rather than lying down as you would on some sleds, you sit across the top of the tube, holding onto the handles on either side for support, and zip down the slope.
