The question of how much atmosphere should be in the wheels of the Xiaomi electric scooter is one of the most critical for owners of this popular device. Many beginners ignore this parameter, relying on intuition or pumping tires “on the eye”, which ultimately leads to frequent punctures, rapid wear of the tread or even camera failure. Properly selected pressure directly affects the safety of movement, comfort when driving on irregularities and, especially important for electric transport, the real range of the battery.
The manufacturer clearly regulates the pumping parameters, but they often vary depending on the specific model of the scooter, whether it is a classic Mi Electric Scooter 1S or the more powerful Xiaomi Pro 2. Insufficient pressure makes the motor work with overload, trying to turn the soft wheel, which leads to overheating of the controller. Excess pressure turns the trip into a shaking and increases the risk of explosion of the camera when you fall into a hole. In this article, we will analyze all the technical details so that you can adjust your gadget perfectly.
Factory standards and the impact of pressure on operation
Xiaomi engineers run thousands of hours of tests to determine the ideal parameters for each model. For most of the current electric scooters of this brand, such as the Mi Electric Scooter Essential or Pro 2, the recommended pressure range is from 3.5 to 4.5 atmospheres (Bar), which is within this range of pneumatic tires are able to effectively cushion small irregularities of asphalt, while maintaining sufficient rigidity for a stable run-down. If you fall below 3 atmospheres, the risk of a snakebite (snap camera break) when you repeatedly hit the age.
It's important to understand that tire pressure is not a static parameter, it varies with the ambient temperature and the heating of the tire during the movement. In summer, in hot weather, the air inside the chamber expands, and the pressure can increase by 0.2-0.3 atmospheres. In winter, on the contrary, the rates fall. So the check must be done on "cold" rubber, when the scooter stood without movement for several hours.
⚠️ Warning: Never check or adjust the pressure immediately after a long trip.A heated camera will show falsely inflated values, and after cooling the wheel will be underperformed, which is dangerous for the design.
Factory compliance allows the electric motor to operate normally, delivering the manufacturer's stated speed and acceleration dynamics, and neglecting this rule is the most common cause of premature wear on the transmission and the motor-wheel itself.
Table of recommended values for different models
Different scooters have different engine weights and power, which dictates their requirements for wheel stiffness. Below is a summary table that will help you quickly navigate. Note that the values are listed in Bar (atmospheres) and PSI (pounds per square inch), as the scales at the pumps may differ.
| Model scooter | Pressure (Bar) | Pressure (PSI) | Max, load. |
|---|---|---|---|
| Xiaomi Mi Scooter 1S | 3.5 – 4.0 | 50 – 58 | 100 kg |
| Xiaomi Pro 2 / Pro 2+ | 3.5 – 4.5 | 50 – 65 | 100 kg |
| Xiaomi Essential | 3.5 – 4.0 | 50 – 58 | 90 kg |
| Xiaomi Scooter 3 / 3 Lite | 3.5 – 4.5 | 50 – 65 | 100 kg |
Using a pressure gauge with high accuracy will allow you to withstand these values with an error of up to 0.1 atmosphere. For heavy riders (weighing more than 90 kg), it is recommended to keep the pressure closer to the upper limit of the range indicated in the table, this compensates for the additional load on the camera and reduces the likelihood of breakdown.
If you plan to drive predominantly on poor asphalt or pavers, you can slightly reduce the pressure to a minimum threshold (3.5 Bar) to improve traction and comfort. However, for smooth urban roads and maximum energy efficiency, it is better to aim for values of 4.0-4.2 Bar.
Effect of pumping on range and speed
Many users don't realize that soft wheels are the main enemy of electric scooter autonomy. When the pressure is below normal, the area of contact between the tire and the road increases, which leads to an increase in rolling resistance. The motor has to use up battery power to maintain speed. It has been experimentally proven that the difference in range between wheels pumped up to 3.0 Bar and 4.5 Bar can be as high as 15-20%.
In addition, the soft wheel is worse at keeping the trajectory at high speeds. The scooter becomes more "sluggish" in acceleration, and the top speed may decrease slightly due to increased friction. If you notice that your Xiaomi has started to travel less than kilometers on a single charge, first check the compressor and tire pressure.
⚠️ Attention: Riding on flat wheels can damage the internal structure of the tire and even cause the engine wheel to fail due to a violation of the heat sink.
On the other hand, pumped wheels (above 5.0 Bar) will make the scooter stiff and slippery, especially on wet pavement, which reduces safety and increases braking distance. The optimal balance is the middle ground recommended by the manufacturer.
💡
Use a car pump with a pressure gauge for precise pumping. The regular pumps in the kit often don't have a scale or show inaccurate data.
Instructions: how to properly check and pump the wheels
The maintenance procedure for the wheels is simple, but requires a certain order of action. First you need a pump.Combined with some models comes a simple pump, but for regular maintenance, you should get a compact electric pump Xiaomi Mijia or equivalent with a digital pressure gauge.
Before you start, make sure the nipple is clean and has no dirt or water in it. Unscrew the safety cap. If you're using a mechanical pump, plug it in and do some pumping, then check the pressure. If you're using an electronic device, just plug the hose in and turn on the power.
- Relieve the current pressure if it is above normal by gently pressing the center of the nipple.
- Connect the pump and pump the wheel to the desired value.
- With a quick movement, disconnect the hose to minimize air loss.
- Check the pressure with the pressure gauge again and twist the protective cap.
It is important to perform this procedure regularly, at least every two weeks, as even serviceable cameras are prone to natural diffusion of air through rubber walls.
☑️ Monthly wheel check
Seasonal Features: Summer and Winter
The temperature changes the maintenance of the equipment. In summer, when the asphalt is hot to 50-60 degrees, the air in the chamber expands. If you pump the wheels to a maximum (4.5 Bar) in a cool garage and then go out in the sun, the pressure can jump to critical values. So in the hot season, it is better to stick to the average values (about 4.0 Bar).
Winter scooters are a separate subject, but if you're going out, remember: in the cold, the pressure drops. The rubber blubbers and loses its elasticity. In the cold season, it's recommended to keep the pressure closer to the upper limit, but not exceed it, so that the camera does not burst in the cold. Also in the winter, the condition of the tread is critical.
⚠️ Warning: Do not leave an electric scooter with pumped wheels in extreme cold or in direct sunlight for a long time. Temperature changes can destroy the structure of the rubber.
Regular monitoring of tire conditions in the off-season will help avoid unpleasant surprises.Sharp temperature spikes are the main enemy of stable pressure.

Frequent problems and their solution
Even with proper care, there can be problems. The most common is spontaneous pressure reduction. If the wheel deflates faster than in a week, you have a micropuncture or a leaky nipple. Check the nipple with water on it, the appearance of bubbles will indicate a problem.
Another problem is the wheel beat, which can happen if the camera inside the tire is twisted or if the pressure is uneven, in which case you have to completely lower the wheel, straighten the camera and pump it again, and sometimes the beat causes the rim or the tire to deform after hitting the curb.
If you notice that the scooter is moving aside when braking, check the uniformity of pressure in the front and rear wheels. The difference in the rigidity of the wheels can disrupt the course stability.
💡
Stable tire pressure is 50 percent of your success in the long life of your scooter, and it costs you more to be lazy about it.
