Changing the Tire/Wheel
Install a new tire when the tread is less than 1.0 mm (0.04 inches) deep
or when the tire is punctured.
CAUTION
It is recommended that you bring your tire/wheel assembly to a Ninebot
authorized service center when installing a new tire on the wheel.
Performing this repair without the proper tools could result in damaging
the wheel.
If you cannot bring your PTR to a Ninebot authorized service center, we
suggest you replace the whole tire/wheel assembly. Follow the steps
below to remove the tire/wheel assembly.
1. Make sure the PTR is unplugged and powered off
2. Raise the PTR on blocks so the wheels are off the ground.
3. Use a flathead screwdriver to pry loose the wheel cap.
4. Use a 10 mm socket wrench to remove the three nuts.
5. Remove the tire/wheel assembly.
6. Install the tire/wheel assembly in the reverse order of removal.
7. Make sure the tire is inflated to the specified pressure (see Tire
Pressure).
