Electric vehicle owners often wonder about the proper maintenance of the chassis, because it is the quality of rubber that determines the comfort and safety of movement. Tire pressure is one of the key parameters that directly affects the range, acceleration dynamics and cushioning of road irregularities. Many users mistakenly believe that the softer the wheel, the better it swallows pits, but this is not quite true.
Low pressure increases the contact spot, which improves grip, but at the same time increases the risk of puncture of the camera and reduces the efficiency of braking. Too high-pumped wheel makes the ride stiff and can cause the camera to rupture when overheated. So it is important to maintain the balance recommended by the manufacturer Xiaomi and proven practice of operation in various conditions.
In this article, we will detail how much atmospheres the wheels on popular scooters can pump, how often pressure tests are needed, and what tools are needed to do so. Properly pumping will prolong the life of rubber and ensure stable road traffic behavior, and ignoring these norms can lead to costly repairs or injuries.
β οΈ Warning: Never test the pressure immediately after a long trip when the tires are warmed up. 15-20 minutes, otherwise the gauge readings will be incorrect.
Optimal tire pressure according to models
The Chinese giantβs range of electric scooters is constantly expanding, and each series has its own specifications. For the classic Xiaomi M365 model and its modification Pro, pressures in the range from 3.0 to 3.5 atmospheres (Bar) are considered the gold standard, which provides sufficient rigidity for effective coasting and acceptable cushioning.
Newer versions, such as the Xiaomi Pro 2 and Essential, feature reinforced sidewall tires, allowing for a few variations in pumping parameters. The recommended pressure here is often indicated on the sidewall of the tire itself, but it should usually not exceed 4.0-4.5 Bar to prevent rubber from bloating. If you weigh more than 90 kg, it makes sense to keep the indicator closer to the upper limit of normal.
Consider that the rear wheel is under a lot of stress due to the weight of the rider and the motor. Therefore, some experienced users recommend pumping the rear tire 0.2-0.3 atmosphere more than the front one. This helps compensate for drawdown and improves handling at high speeds. However, a significant difference can lead to uneven tread wear.
Effects of Rider Weight and Road Coverage
There is no universal figure for everyone, as the physics of the process depends on the driver's weight.A light rider (up to 60 kg) will be more comfortable at a pressure of about 2.8-3.0 Bar, since high pressure will make the trip too shaky.For a heavy user (over 100 kg), the minimum threshold should start from 3.5-3.8 Bar to avoid breaking the camera against the wheel rim when hitting the pit.
The type of pavement also dictates its operating conditions: on perfectly smooth asphalt, you can afford higher pressures for maximum energy efficiency. In such conditions, rolling resistance is minimal, and the battery is spent more economically. If you plan to travel on pavements or tiles, the pressure is better reduced to 2.8-3.0 Bar.
Why can't you ride flat tires?
So more frequent pumping is required in the fall/winter period, and ignoring this fact can lead to you getting on the road with critically low pressure, even if you pumped the wheels yesterday.
Table of recommended pressure values
For user convenience, we have organized data on the main models of electric vehicles, and use this table as a baseline, adjusting values based on your weight and riding conditions, and you can always find accurate data on the side of your device's tire.
| Model scooter | Min. pressure (Bar) | Optimal (Bar) | Max. Pressure (Bar) |
|---|---|---|---|
| Xiaomi M365 | 2.8 | 3.2 - 3.5 | 4.0 |
| Xiaomi M365 Pro | 3.0 | 3.5 - 3.8 | 4.2 |
| Xiaomi Pro 2 | 3.2 | 3.6 - 4.0 | 4.5 |
| Xiaomi Essential | 2.8 | 3.0 - 3.4 | 3.8 |
Note that the values are given in atmospheres (Bar), which are most often used on pressure gauges in the CIS. In English documentation, the designation PSI may be found. For translation, use the ratio: 1 Bar β 14.5 PSI. For example, 3.5 Bar is about 50 PSI.
How to measure and pump the wheels correctly
To make accurate measurements, you'll need a high-quality pressure gauge. Sensors built into cheap pumps often have a large margin of error, so it's better to use a separate device or pump with a digital display. The measurement process is simple: remove the cap from the nupple, press the pressure gauge tightly and record the reading.
If the pressure is below normal, you need to pump the wheel, you can use a car compressor, a hand pump or a special electric pump Xiaomi Mijia. It is important not to overdo it when pumping, because it is more difficult to raise the pressure sharply above normal than to blow excess air. Do this in short bursts, constantly monitoring the process.
βοΈ Tyre pressure check
After pumping, make sure to check the tightness of the joint by applying a little saliva or soapy water to the nipple. If bubbles appear, then the spool poisons the air and needs to be twisted or replaced, such a simple procedure will help to avoid a sudden descent of the wheel in the way.
Typical errors and their consequences
One of the most common mistakes is to ignore regular checks. Air tends to gradually penetrate through the rubber pores, so the pressure drops by about 0.1-0.2 Bar per week even without visible punctures. Riding on half-deflated wheels leads to rapid wear of the tread at the edges and deformation of the cord.
The other extreme is pumping tires in the hope of increasing range, and although rolling resistance does decrease, safety suffers, a pumped wheel is less tractable, especially on wet pavement, and the risk of aquaplaning increases, and the camera is more likely to rupture if the engine or brake system overheats.
β οΈ Warning: Do not use compressors with a high flow of air without a pressure gauge to pump tires. In seconds, you can exceed critical pressure and blow up the camera.
Cheap cameras from Chinese brands may not keep the pressure or quickly become obsolete, and it is better to use original components or proven analogues from well-known rubber manufacturers.
Care for cameras and tires
To keep the wheels running for long, you need to monitor not only the pressure, but also the overall condition of the rubber. Regularly clean the tread from small stones, glass and metal shavings that can get stuck in the drawing. Over time, they can pierce the camera from the inside.
Keep the scooter in a dry room, away from direct sunlight and heat sources. Ultraviolet and high temperature destroy the structure of the rubber, making it brittle (breakable) and prone to cracks. If you do not plan to ride for a long time, lift the scooter so that the wheels do not touch the ground, or periodically scroll them.

To prevent punctures, you can use a special sealant for tubeless tires (anti-puncture), which seals small holes up to 3 mm in diameter right while driving.
Replacing worn tires in a timely manner is a guarantee of your safety, and if the tread has worn off to a wear indicator or there are deep cracks on the sidewalls, it becomes dangerous to operate the vehicle, and in such cases, no pressure will save the situation.
