Xiaomi electric scooters are deservedly considered one of the most popular personal mobility tools in the world, but their reliability and comfort directly depend on maintenance, and first of all – on the condition of the wheels.
Many owners ignore the pressure check until they are faced with a sharp drop in mileage or worse, a camera puncture, although the right air balance is the foundation of safety.
In this article, we will discuss in detail how many atmospheres or PSIs need to be pumped depending on the model and weight of the rider, so that your Mi Electric Scooter lasts long and delights with smooth running.
Why it is important to monitor tire pressure
The underperformed wheels create a huge rolling resistance, forcing the motor to work at the limit of possibilities, which leads to overheating of the controller and rapid discharge of the battery.
At low pressure, the camera inside the tire begins to rub against the inner surface of the tire and rim of the disc, which in 90% of cases leads to the so-called “snake bite” – a double puncture that is difficult to seal.
On the other hand, over-pumped tires make the ride tough and dangerous, as the over-pumped wheel loses the ability to cushion asphalt irregularities, transmitting vibration to the frame and electronic components.

⚠️ Attention: Riding on flat wheels even for several kilometers can completely destroy the camera and damage the structure of the tire, making it unsuitable for further operation.
Regular pressure check with a pressure gauge allows you to extend the service life of the tires and maintain the manufacturer's declared range.
💡
Optimal pressure is a trade-off between comfort (less pressure) and mileage/puncture protection (more pressure).
Table of pressure standards for different models Xiaomi
The manufacturer sets different recommendations for different versions of scooters, as they have different weight, engine power and wheel design.
Below is a summary table that will help you quickly navigate the necessary parameters for your Xiaomi model.
| Model scooter | Pressure (Bar/Atm) | Pressure (PSI) | Max. load (kg) |
|---|---|---|---|
| Xiaomi M365 | 3.5 – 4.0 | 50 – 58 | 100 |
| M365 Pro / Pro 2 | 3.5 – 4.5 | 50 – 65 | 120 |
| Essential (Lite) | 3.5 – 4.0 | 50 – 58 | 100 |
| Xiaomi Scooter 3 / 4 | 3.5 – 4.5 | 50 – 65 | 120 |
| Xiaomi Pro 2 Mercedes | 4.0 – 4.5 | 58 – 65 | 120 |
Note that the values in the table are averaged, and for riders with above-average weight, it is recommended to adhere to the upper limit of the range.
Using a pump with a digital display greatly simplifies the process, allowing you to monitor the pumping process in real time without the risk of error.
The effect of rider weight on wheel pumping
Standard manufacturer recommendations are often designed for the average user, but the individual weight of the rider plays a key role in the choice of pressure.
If your weight is above 80-90 kilograms, a standard 3.5 atmosphere may not be enough and the wheel will be severely deformed under load, increasing the risk of breakdown.
For heavy riders, the optimal solution is to pump the wheels up to 4.5 atmospheres (about 65 PSI), which will provide the necessary stiffness and protection of the camera.
At the same time, light users (up to 50 kg) do not make sense to swing the wheels to the maximum, as this will lead to excessive shaking and reduced traction.
Adjusting pressure depending on weight is an easy way to customize the behavior of the scooter to your needs without making changes to the design.
Seasonal Features: Summer and Winter
The ambient temperature directly affects the pressure inside the tire: when cooling, the air is compressed, and the pressure drops, and when heated, it expands.
In winter, when the temperature drops below zero, the pressure in the wheels can drop by 10-15% compared to summer indicators, which requires periodic pumping.
In summer, especially when traveling on hot asphalt, the air inside the chamber heats up, and if you pumped the wheels “to zero” along the upper limit, there is a risk of rupture.
⚠️ Warning: Never lower hot wheels immediately after a long trip, wait for them to cool to room temperature for accurate measurements.
Experienced owners recommend keeping the pressure slightly above normal in winter (for example, 4.2-4.5 atm) to compensate for the natural drop in the cold.
💡
Check the pressure in the wheels in the morning, before the first trip, when the scooter has not yet had time to heat up from the operation of the engine and friction against the road.
Instructions: how to measure and pump correctly
To perform the procedure, you will need a pump with a pressure gauge, which can be electric (car or special for scooters) or mechanical.
First, remove the protective cap from the wheel nipple and, if a car pump is used, gently blow a little air to knock the valve down.
Tightly press the head of the pump against the nipple and start pumping, periodically stopping to check the readings on the pressure gauge.
☑️ Proper pumping of wheels
Once you reach the desired value, quickly disconnect the pump and twist the cap to prevent dust and moisture from entering the nipple.
If you use an electric compressor, many Xiaomi models allow you to adjust the target pressure, after which the pump itself will shut down.
Common Mistakes and Myths
There is a misconception that the softer the wheel, the better the cushioning, but for Xiaomi chamber wheels, this is the way to quickly fail.
Some users try to pour a sealant or anti-puncture into the wheels, which can disrupt the wheel's balancing and lead to beating at high speeds.
Another common mistake is ignoring visual inspection: even at normal pressure, an old, cracked tire will not be able to keep the camera from damage.
Should I switch to a tyreless tire?
It is important to understand that the camera and tire are consumables and their replacement or maintenance should be done regularly.
