Xiaomiβs electric vehicles have become the benchmark for urban mobility, but even the most reliable devices require regular maintenance. One of the most critical parameters for a comfortable and safe ride is the right tire pressure. Insufficient tire pumping leads to rapid battery discharge, engine overheating and, most dangerously, punctures and βpinch flatsβ of the cameras.
Many owners are faced with the question: what kind of pressure should be maintained and how to pump the wheels? In this article, we will examine the tyre maintenance process in detail, examine the differences between scooters models and give exhaustive answers to technical nuances. Proper preparation for the trip begins not with the device, but with the check of rubber.
Why it is important to monitor tire pressure
Ignoring the manufacturer's recommendations for tire pumping is a direct route to expensive repairs. When the pressure drops below normal, the stain of contact between the wheel and the road increases, which creates excessive friction. This causes the motor-wheel to work at increased load, consuming more energy and heating faster, as a result, you lose up to 30% of your range on a single charge.
In addition, a defective tire becomes vulnerable to mechanical damage, when hitting a curb or pit, the soft wheel crumples to the rim, and the camera clamps between them, which causes a characteristic double puncture, which is difficult to seal in the field, and low pressure also negatively affects cushioning: instead of springing, the wheel begins to hit the rim, which can damage the spokes or the design of the disk itself.
β οΈ Attention: Flowing wheels can cause permanent damage to the internal structure of the tire, requiring a complete rubber replacement rather than just a camera repair.
On the other hand, over-pumped tires also carry risks: Excessive pressure makes the scooter rigid, transferring all vibrations from the road surface to the frame and electronics, which can lead to loosening of the mounts and damage. BMS-So the middle ground, as specified in the specification, should be as accurate as possible.
Pressure standards for different Xiaomi models
Different scooters have different weights, engine power and wheel designs, so they have different pumping requirements. The standard range for most urban models, such as the M365 and Pro 2, is between 3.5 and 4.5 atmospheres (bar).
Below is a table with recommended pressure values for popular models:
| Model scooter | Diameter of the wheel | Recommended pressure (PSI) | Recommended pressure (Bar) |
|---|---|---|---|
| Xiaomi Mi Electric Scooter M365 | 8.5 inches | 45-50 | 3.0-3.5 |
| Xiaomi Mi Electric Scooter Pro 2 | 8.5 inches | 50-55 | 3.5-3.8 |
| Xiaomi Electric Scooter 4 Pro | 10 inches | 40-45 | 2.8-3.1 |
| Xiaomi Mi Scooter Essential | 8.5 inches | 45-50 | 3.0-3.5 |
It's important to remember that tire pressure is affected by ambient temperature, and in winter or cold season, the air compresses and the pressure drops, and in summer, especially after a long trip, it can increase significantly due to heating of the tire, so it's best to check the indicators for cold, before you start driving.
Essential tools for pumping
To perform the wheel maintenance procedure, you will need the minimum set of tools that every electric vehicle owner should have: the main appliance is the pump, it can be manual (legged or piston) or electric. Electric compressors are preferable, since they allow you to accurately set the target pressure and shut down automatically.
It is essential to have a pressure gauge if your pump is not equipped with a built-in digital sensor. Mechanical hand gauges often have an error, so it is better to use electronic analogues. Also remember to prepare a nupsel plug to protect the valve from dust and moisture after pumping.
- π² Electric compressor β provides fast and accurate pumping, operates on the battery of a scooter or a poverbank.
- π§ Manual pump β a reliable backup that does not require power, but requires physical effort.
- π Digital pressure gauge β required for accurate pressure monitoring, especially if the pump does not have a built-in sensor.
If you plan to service the scooter regularly, it makes sense to purchase a specialized mini compressor that attaches to the deck or fiddles in the bag.Some Xiaomi models are compatible with pumps that connect directly to the scooter charging port, which is very convenient on the road.

Use a pump with a digital display: it allows you to set an exact pressure value and automatically stops the air supply, eliminating the risk of pumping the wheel.
Step-by-step: how to pump the wheel
The process of pumping the wheels on Xiaomi scooters is technically simple, but requires attention to detail. First find the nipple on the rim of the wheel. On most models it is closed with a rubber or plastic cap that must be carefully removed. If the plug is boiling, do not pull it sharply so as not to damage the thread.
Before you plug the pump in, just press the nipsel spool lightly to release some air, which helps clear the valve of dust and dirt that might have gotten there, then put the pump hose tightly on the nupple, and it's important to lock the connection so that the air does not poison the sides while the compressor is running.
βοΈ Checklist before pumping
Turn on the pump and watch the pressure gauge. Once the arrow or numbers reach the desired value, stop the air supply. Quickly disconnect the hose and immediately twist the protective cap. The sharp sound of the outlet air when disconnected is normal, as long as there is no hissing after installing the plug.
β οΈ Warning: Never leave a working compressor unattended. A sudden surge in pressure can cause the chamber to rupture if the process is not stopped in time.
Features of service of tubeless and chamber tires
Itβs important to understand what type of rubber youβre dealing with. The early Xiaomi M365 models were often supplied with chamber wheels, while newer versions like the Pro 2 and 4 Pro are predominantly equipped with tubeless tires. They have similar pumping principles, but there are critical differences in puncture behavior.
A tubeless tire requires a tighter fit to the rim, and if you have a fully deflated tire, you may not be able to pump it with a conventional pump, because the tire sides may not fit in, and in such cases, you need a powerful short-term airflow that only special compressors or CO2 cylinders can provide.
Chamber wheels are more forgiving in this regard: even if the camera is flat, it can be pumped with any pump and it will take shape inside the tire, but the cameras are more prone to snake bites and require checking for scuffs against the inner walls.
How to distinguish a tubeless tire from a chamber tire?
Frequent problems and their solution
In the process of operation, owners may encounter a situation where the wheel does not hold pressure. If after pumping the air quickly comes out, first check the nipsel spool. Sometimes it is enough just to twist it or replace it if the thread is broken. Also common cause is a microcrack in the rim or the entry of small debris between the tire and the rim.
Another problem is a hernia on the wheel, which is the swelling of the tire that occurs because the internal strands of the cord break, and it becomes a beating when you spin, and it's dangerous, and it's strictly forbidden to operate a herniated scooter because it can cause the tire to rupture at speed.
- π Permanent loss of pressure β most likely a puncture or leaky nipsel.
- π Noise when driving - perhaps a stone or nail stuck in the tread.
- π Visual deformation β a sign of the destruction of the tire structure or improper installation.
You can use soap solution to look for a puncture in chamber wheels, put a pumped camera on it, look for bubbles. In tubeless tires, this method works worse, because the sealant inside can immediately tighten the small holes, which requires the removal of the tire and visual inspection of the inner surface.

Regular pressure checks (every 1-2 weeks) prolong the life of the battery and motor, and prevent 90% of sudden punctures on the road.
Prevention and advice on extending the service life
To keep the wheels running for a long time, try to avoid riding on rough terrain if your scooter is not designed for this. Sharp stones, broken glass and metal shavings are the main enemies of rubber. After traveling on wet asphalt or dirt, it is advisable to wipe the wheels, since reagents and dirt accelerate the aging of rubber.
If you plan to stay away from the scooter for a long time (for example, in winter), do not leave it on flat wheels. Being under load for a long time in a compressed state deforms the rubber. It is best to hang the scooter or put it on stands so that the wheels do not touch the floor.
β οΈ Warning: Do not use car sealants to repair the wheels of the scooter.They can be too viscous and upset the balance of the small wheel, which will lead to vibrations and breakage of bearings.
Replacing worn rubber in a timely manner is a guarantee of your safety. If the tread has worn down to the indicators or there are deep cracks in the sidewalls, you can not postpone buying new tires. Remember, saving on rubber can cost more than repairing electronics after a fall.
