Inner Tube - 145x70-6 - Bent Valve - 6 Inch

It refers to the tire's dimensions: approximately 145mm wide, with a 70% aspect ratio (sidewall height is 70% of width), designed for a 6-inch rim diameter.

It is suitable for 6-inch rims that are designed to accommodate tire sizes listed, such as 145x70-6, and have a standard valve stem hole.

While there might be some flexibility, it's best to match the tire size as closely as possible for optimal fit and performance. This tube is specifically designed for the listed sizes.

A Schrader valve is the standard type of valve used on car tires, bicycles, and many other pneumatic applications. It's characterized by a single pin in the center of the valve stem.

Signs include frequent deflation, visible damage like cracks or bulges, or if the tube is old and brittle. If you suspect a leak, try submerging the inflated tube in water to find bubbles.

The bent valve primarily affects convenience during inflation. It does not typically alter the fundamental performance of the inner tube itself, but it can make maintenance easier.

Information regarding warranty is not provided in the product details. Please refer to the retailer or manufacturer's official documentation for warranty information.

Ensure the valve cap is removed and the Schrader valve core is functional. Check that the tire is properly seated on the rim and not pinching the valve stem.

Check for punctures in the inner tube or damage to the tire. Ensure the valve stem is not leaking. Verify the tire bead is properly sealed against the rim.

Check that the inner tube is evenly seated within the tire and not bunched up. Ensure the tire pressure is correct and consistent.

The bent valve is designed for easier access, but if significant difficulty persists, ensure you are using an appropriate pump connector for a Schrader valve.
