Changing a Flat Rear Tyre on a Pure Air Scooter
Let’s go through how to easily change the tyre and inner tube on the rear wheel of a Pure Air scooter.
The second-generation Pure Air scooters, including Pure Air Go, Pure Air Pro, and Pure Air Pro LR, have the same wheels on the front and rear, so you can follow this guide without any issues regardless of your model.
🛒 We will soon offer 10×2.125-inch tyres for your Pure Air.

Removing the Rear Wheel
First, I’ll lay the scooter on its back.
Next, I’ll use a large 8mm Allen wrench to loosen the two nuts on the left and right sides of the rear wheel.
As for the order of the washers, we have an initial locking washer, a small flat washer, and a third split washer.
Now, you can pull the wheel backward, being careful not to pull too hard on the motor cable. Retrieve the washers on the left and right sides of the axle.
And place the wheel back onto the scooter.
Removing the Old 10×2.125 Tyre
I remove the small cap from the inner tube and ensure there’s no air left in the tyre.
Next, I apply a little soapy water around the rear wheel. This significantly eases the disassembly process as the tyre slides more easily.
I push the lower part of the tyre into the rim, causing the opposite side to come out slightly.
I gradually remove the first sidewall of the tyre by going around the wheel with tyre levers.
Next, I push the valve of the inner tube inside the rim.
I pull the valve out of the wheel and remove the flat inner tube.
Then, I can remove the second part of the tyre by hand.
If our tyre isn’t too worn, and we want to reuse it, we ensure there are no debris inside.

Mounting the New Tyre
Next, I apply some soapy water around the wheel and tyre.
We install the first side into the wheel.
If you find it difficult to put on your tyre, don’t hesitate to use a tyre lever to assist with the installation.
Then, I press my tyre around the valve hole and insert the inner tube valve into its housing.
And I slide the new 10×2.125 inner tube with a bent valve into the tyre.
I apply a little soapy water for lubrication. I press and push the lower part of the tyre into the rim.
I gently work my way towards the valve by pressing on the tyre’s edges.
If it gets stuck, I can, of course, use a tyre lever.
Installation of the Repaired Rear Wheel
Now that the tyre is mounted, I place the wheel back on the rear fork, making sure not to forget the two washers.
I tighten the rear wheel of our Pure Air with the two screws and washers.
Inflating the Pure Air Tyre
And all that’s left is to inflate the rear tyre to 36 PSI or 2.5 bars.
