Owning an electric vehicle requires regular maintenance, and the key aspect here is the condition of the tires. Many users wonder how to pump the Xiaomi scooter wheel, since the correct pressure directly depends on the dynamics of acceleration, range and driving safety. Insufficient pressure in the cameras Xiaomi Mi Electric Scooter Pro 2 or M365 leads to rapid wear of rubber, increased risk of puncture and a significant increase in battery power consumption.
On the other hand, over-pumped tires make driving tough, reduce traction, and can cause the chamber to rupture when heated. In this article, we will discuss in detail the pumping process, the tools needed and optimal parameters for different operating conditions. Regular inspection will help to avoid unpleasant situations on the way.
Optimal pressure: standards and tables
Before starting pumping, you need to clearly understand the target values of pressure. The standard indicator for most models, including the Xiaomi M365, Pro and Pro 2, is the range from 3.5 to 4.5 atmospheres (Bar). However, the specific figure depends on the weight of the rider and the type of road surface. For an adult weighing more than 80 kg, it is recommended to keep the pressure closer to the upper limit of 4.0-4.5 Bar.
Using a pressure gauge is mandatory because it is impossible to determine the exact pressure in Xiaomi tires by eye; relying on the sensation of a finger when pressing a tire is a gross mistake that often leads to misuse of vehicles; accurate measurements allow you to extend the life of the camera and rim.
| Rider weight | Type of coating | Recommended pressure (Bar) | Recommended pressure (PSI) |
|---|---|---|---|
| 60 kg | Smooth asphalt | 3.2 - 3.5 | 46 - 50 |
| 60 - 80 kg | Mixed cycle | 3.5 - 4.0 | 50 - 58 |
| 80 - 100 kg | Asphalt/Tile | 4.0 - 4.5 | 58 - 65 |
| over 100 kg | Hard coating | 4.5 - 5.0* | 65 - 72* |
Note that exceeding the 5.0 Bar can be dangerous for Xiaomi’s regular cameras, especially in hot weather.The maximum allowable pressure for Xiaomi’s regular cameras is usually 50 PSI (about 3.4-3.5 Bar) according to the labeling on some lots, however, practice shows resistance to 4.5-5.0 Bar when using quality counterparts. Always check the marking on the sidewall of your particular tire.
⚠️ Warning: Never take pressure immediately after a long trip. When heated by friction and compression, the camera shows inflated pressure, which is not an objective indicator for cold pumping.
Selection of a pump for an electric scooter
Xiaomi’s wheel pumping process is greatly simplified with the right equipment.The full-time pumping port is located on the inside of the rim and has a Schrader-type (AV) threaded connection similar to car nipples, but often requires more careful handling due to the depth of the landing in the disk.
The most convenient solution is to use portable electric compressors such as the Xiaomi Mi Portable Electric Air Compressor, which is perfectly integrated into the ecosystem, has a digital pressure gauge and automatically shuts down when it reaches a set value. The alternative is classic foot or hand pumps, but they require physical effort to reach 4-4.5 atmospheres.
- 🔋 Electric compressor: Battery-powered, connects directly to the wheel port, ideal for pumping on the road.
- 🦶 Foot pump: Reliable mechanics, does not require battery charge, but requires fixing the scooter with your feet while working.
- 🤲 Manual pump: Compact option for emergency pumping, but pumping the wheel up to 4 atmospheres manually is extremely time-consuming.
⚠️ Attention: When using powerful car compressors, be careful.The airflow may be too strong, leading to a sharp surge in pressure and the camera rupture.Dosing the air supply with short presses.
Step-by-step: how to pump the wheel
The pumping process on the Xiaomi M365 and Pro scooters is almost identical, but requires attention to detail. First, you need to access the nipple. On models with whole discs, the pump hole is closed with a rubber plug that must be carefully removed. If the plug is lost, it is recommended to purchase a new one so that moisture and dirt do not get inside the disk.
Next, you need to prepare the pump. If you use a compressor with a flexible hose, attach it to the nipple to the end. If you use a rigid tip (as on some bicycle pumps), make sure that it sits tightly on the thread, otherwise the air will come out and not into the chamber. For Pro 2 models, where the wheel is removed more difficult, they often use long-hose pumps to avoid dismantling the wheel.
☑️ Wheel pumping algorithm
Once you've reached the right pressure, quickly unplug the pump hose. Because of the design of the nipple, some of the air can come out at the time of undocking, which is normal. Immediately close the hole with a rubber plug. If there's no plug, you can temporarily use a piece of chewing gum or a special cap, but this is a temporary solution.
💡
To make it easier to screw the pump hose onto the wheel's nipple, lubricate the thread with a drop of silicone lubrication, which will also prevent corrosion of the metal.
Features of service of tubeless and chamber tires
Owners of Xiaomi scooters often face a dilemma: regular chamber tires or switch to tubeless. Staff cameras are prone to punctures and require regular pressure checks. tubeless tires, in turn, better hold punctures thanks to sealant, but more difficult to install and require a perfectly flat rim.
If you have chamber tires installed, make sure that the camera is not squeezed between the tire and the rim. When pumped to high values (4.5 Bar and above), the risk of "biting" the camera increases. In tubeless systems, it is important to periodically (every 3-4 months) check the amount of sealant inside and update it, as it has the property to dry out.
- 🛠️ Chamber tires: Cheaper to maintain, easier to change, but higher risk of puncture and the appearance of a "snake bite" at low pressure.
- 💧 Cutless tires: Self-tighten with small punctures, better to hold pressure, but require special tires and installation skills.
- 🔄 Hybrid option: Install a durable camera (like Kenda) in a tubeless tire for reliability.
When switching to a tubeless system, a special sealant is often used, which fills microcracks and small holes, but if you decide to go back to the cameras, carefully clean the inner surface of the tire of the dried sealant, otherwise it will interfere with the installation of the new camera.

Diagnostics of wheel problems
There's a little bit of a problem with the Xiaomi scooter wheels, if you notice that the range has decreased by a little bit. 10-15%, And the acceleration rate has dropped, and the first thing you need to check is the tire pressure, and the lower pressure is also indicated by the milder cushioning and the appearance of excess vibrations transmitted to the deck.
Frequent punctures can indicate not only poor road conditions, but also rim problems. If the edges of the spoke or inner surface of the disc have sharp burrs, they will cut through the camera from the inside with each bump, in which case simply changing the camera will not help - you will need to grind the rim or install a flipper (protective tape).
Another common problem is the etching of air through the nipple. If the wheel descends in 2-3 days without visible punctures, try to tighten the nut of the nipple (if any) or replace it. Sometimes the spool inside the nipple gets clogged with dirt or loses its tightness.
💡
A constant loss of pressure without visible punctures often indicates leakyness of the nipple or the presence of microcracks in the rim of the disc.
