Off road tyres for 6,5" hoverboard motors (240mm OD)

Intro:

These are the rear tyres developed for the Breezebuggy outdoor play car (Paid model),

but they can probably be used in other applications where hover board motors are desirable.

The size allows for good volume to incorporate some cushioning as well as increasing the top speed for lighter applications. A standard 36V system hoverboard motor with this tyre will do a bit over 20km/h.

The motor hub does not protrude past the tyre.

Printing:

I have had good results with printing these from Recreus Filaflex 82A, but any flexible filament of suitable softness can be used.

The mentioned works well for lighter loads (10-25kg per tyre) 0,6mm nozzle with 4walls and 15% gyroid infill. This results in a fairly stiff tyre with decent rolling resistance that can take a beating. 3 walls and lower infill% can be used for an even softer tyre.

The tyre is 240mm outer diameter and fits directly on the hoverboard motor.

Can be printed with a small amount of support material.

Installation:

Due to the flexibility of the mentioned filament, it is possible to install the tyres without disassembling the motors. It requires some strength but is doable. Removing a standard hoverboard tyre without disassembling the rear flange is not reasonably possible without cutting it though. This can be the preffered method if there is motor cabling that cant be split etc.

An easier method for the install is to disassemble the rear flange of the motor and install it that way. Another benefit with this method is the chance to add extra sealing to make the motor more water resistant if that is needed.

The friction fit to the hub has been providing enough torque hold capability in our testing.
