Absolutely! The inside of an inner tube is perfectly smooth, the ideal surface for Dyna Beads. We strongly advise using new inner tubes before installing Dyna Beads. This applies to motorcycles as well. The reason is that old inner tubes often have accumulations of compressor oil, which makes the inside tacky or sticky, which will inhibit Dyna Beads from working properly, or not at all.
Note: Some vehicles, like the Unimog, occasionally run inner tubes in these large aggressive tires. Some of these tubes can add 15 - 20 lbs per tire to the weight, so it's advisable to let us know this when you inquire."Bear in mind though if using these in tubed tires. Inner tubes can be prone to folds and crease if they are improperly installed in a tire. These folds or creases, I would imagine, could/will trap the beads. Rendering them either entirely useless as balancing beads or intermittently functional. JMO
