What size are the wheels? Usually the 6.5" wheels are Tubeless, and sometimes the larger wheels have tubes, I like tubeless, like on cars, but tube tires will stay inflated for longer when sitting "Idle" waiting for you to have fun and ride! :thumbsup:I'm looking for a new rear tire for my mini-chopper. The current tire has a tube. I know the tires on my CAG are tubeless. Are there any advantages to one or another? Are tube and tubeless tires interchangeable or is the rim different?
