Our 145/70-6 inner tube with a 90-degree angled valve stem for go-karts and mini bikes is a great item for the offroad machines that take a lot of hard use. In addition, the 90-degree angled Schrader valve stays close to the rim and out of the way. This makes chucking the air hose easier and far less frustrating.

Many tires in this size are what is referred to as "tubeless pneumatic" and stamped with "TL" on the sidewall. Many offroad enthusiasts add a tube such as this to their "tubeless" tires for a variety of good reasons. Some riders appreciate the dependability of a tube, while others use tubes to help seat a tire to the tire's bead to the rim. As offroad rims can take a beating and suffer slight deformities, this makes a great solution for many people.

The 145/70-6 size tire is very popular on a wide range of go-kart and mini bike models from brands such as Baja, Coleman, Mega Moto, TaoTao, and many others. If you would prefer your offroad tires to roll on the additional layer of dependability that only an inner tube can offer, then this 145/70-6 tube may be just what you need.

Note:When inflating your inner tube, please use your best judgment. The recommended PSI for an inner tube can vary depending on elevation and air pressure, and should not be taken as absolute.
