The Xiaomi M365 remains one of the most popular vehicles in the city, but even experienced owners have a question: how many atmospheres to pump into the wheels to ensure comfortable driving, safety and durability? Incorrect pressure can lead to rapid wear of tires, increased energy consumption or even emergency situations. In this article, we will analyze official recommendations, nuances for different operating conditions and common mistakes that reduce the life of the scooter.
The manufacturer specifies the basics, but in practice, the pressure depends on the weight of the rider, the quality of the road surface, and even the temperature of the air. For example, in heat, tire pressure increases naturally, and in winter it drops. We analyzed the data from the Mi M365 manual, owners' feedback and tips from service centers to make the most complete guide. You will also find here a pressure table for different weight categories, a pressure gauge manual and answers to frequent questions.
Xiaomi’s Official Recommendations for the M365
The operating instructions for the Xiaomi Mi Electric Scooter M365 indicate the optimal tire pressure: 35-40 PSI (which corresponds to 2.4-2.8 atmospheres).
- 👤 Rider weight up to 100 kg;
- 🛣️ Riding on asphalt or flat pavers;
- 🌡️ Air temperature +15…+25°C.
But these numbers are just a reference point. For example, if you weigh more than 100 kg, you should increase your pressure to 3.0-3.2 atm to avoid punching the camera against the rim of the wheel when hitting obstacles. On the other hand, for light users (up to 60 kg), you can reduce the pressure to 2.2 atm, which will make the ride softer, but slightly increase the risk of puncture.
Important: The M365 is equipped with tubeless tires measuring 8.5 inches, and their pressure directly affects:
- 🔋 Range - the higher the pressure, the less rolling resistance and the longer the battery runs;
- 🛡️ Resilience – pumped wheels are worse depreciate, and under-performed worsen management;
- 💥 Risk of puncture – low pressure increases the load on the sidewalls of the tire.
⚠️ Warning: Exceeding pressures above 3.5 atm can cause the chamber to rupture or the tire to detach from the rim, especially for scooters with a mileage of more than 2000 km, where rubber loses elasticity.
Pressure table for Xiaomi M365 depending on weight
The following is a table with recommended pressure values for different weight categories, based on owner tests and service center recommendations, all values are given in atmospheres (atms) and PSI for convenience.
| Rider weight (kg) | Pressure (atm) | Pressure (PSI) | Notes |
|---|---|---|---|
| Up to 60. | 2,2–2,4 | 32–35 | Soft driving, but increased risk of snakebite (rim puncture camera) |
| 60–80 | 2,4–2,6 | 35–38 | Optimal balance of comfort and safety |
| 80–100 | 2,6–2,8 | 38–40 | Recommended by the manufacturer for most users |
| 100–120 | 2,8–3,0 | 40–43 | Increases load on bearings, but reduces the risk of punctures |
| Over 120. | 3,0–3,2 | 43–46 | Requires regular blood pressure checks (every 2-3 days) |
For accurate measurements, use a digital pressure gauge with an error of no more than ±0.1 atm. Analog pressure gauges (especially cheap ones) often show incorrect values. If you do not have a pressure gauge, you can purchase it separately or use a pump with a built-in sensor - for example, the Xiaomi Portable Electric Air Pump (suitable for scooters and bicycles).
How to properly pump the wheels: step-by-step instructions
The process of pumping the Xiaomi M365 wheels has several nuances, especially if you are doing it for the first time.
- Preparation: Put the scooter on a flat surface, turn it off (to avoid accidental start). If the wheels are hot after driving, let them cool for 10-15 minutes - the pressure in the heated tires is higher.
- Removal of the cap: On the nipple of the wheel, unscrew the protective cap. Be careful - do not lose it!
- Pump connection: Tightly put the pump hose on a nipple. The M365 uses a standard Schrader (car) nipple.
- Pumping: Start pumping by periodically checking the pressure with a pressure gauge. The pump should be in High Pressure mode.
- Control: After reaching the desired value, disconnect the pump, quickly put on the cap and repeat the check after 5 minutes (possible leakage through the nipple).
If you use a hand pump, be prepared for physical effort – it takes 150-200 pumps to reach 2.8 atm. an electric pump can handle it in 1-2 minutes, but make sure it does not overheat (especially cheap models).

⚠️ Warning: Never use compressors at gas stations without pressure control! they often give out more than 6-8 atm, which will instantly rupture the tire M365. Always adjust the pressure manually.
Effect of temperature on tire pressure
The pressure in the tires of the scooter varies with the ambient temperature, and this is due to the physical laws: when heated, the air expands, when cooled, it contracts.
- 🌞 In summer, +30°C, tire pressure can increase by 0.3–0.5 atm compared to the measurement in a cool room.
- ❄️ In winter, at -10.°C, the pressure drops by 0.2-0.4 atm, which is especially critical if you keep a scooter in an unheated garage.
If you pumped the wheels to 2.8 atm in a warm room (+20°C) and then rolled the scooter out into the cold (−5°C), the real pressure drops to ~2.4 atm.
- 🔋 Reduced range by 5-10%;
- 🛡️ Deterioration of controllability on a slippery surface;
- 💥 Increased risk of puncture when hitting ice irregularities.
Seasonal recommendations:
- 🌡️ Summer: Pump the wheels 0.2 atms less than the recommended (e.g. 2.6 instead of 2.8) to avoid excessive heat pressure.
- ❄️ Winter: Increase pressure by 0.2 atm (e.g. 3.0 instead of 2.8), as it will naturally drop in the cold.
💡
If you keep a scooter in an unheated room in the winter, check the pressure before each trip, and even overnight, the pressure can drop by 0.3 to 0.5 atm due to the low temperature.
Frequent errors and their consequences
Many Xiaomi M365 owners make mistakes when pumping wheels, which leads to premature wear and tear or accidents.
- Ignoring regular checks, tire pressure decreases over time because of the micropores in the rubber, even in a new tire, the loss is ~0.1 atm per month. If you don't control that, in 3-4 months, you'll be riding half-flattened wheels: 🔋 Increases battery consumption by 15-20%; 🛡️ Makes the scooter less stable on corners; 💥 Increases the risk of a “snake bite” (double puncture of the rim camera).
Use the wrong pump.
Some owners try to pump the wheels with a Presta nipple (thin), but the M365 requires a Schrader (car).
- 🔧 Nipple damage;
- 💨 Air leakage;
- 😤 Loss of time and nerves.
- Wheel pumping: Pressures above 3.5 atm make the ride tough and put more stress on the bearings, and pumped tires make it easier to hit sharp objects, as the rubber becomes less elastic.
Another common problem is the uneven pressure in the wheels, for example, the front wheel is pumped to 2.8 atm, and the rear wheel is pumped to 2.4 atm, which leads to:
- 🔄 I'll take the scooter aside when I'm driving;
- 🛞 Uneven tread wear;
- 🚨 Risk of losing control at high speed.
What to do if the wheel is moving too fast?
When should I deviate from the recommendations?
Although the manufacturer gives clear instructions, there are situations when it is advisable to change the pressure:
- Off-road driving. If you often ride on gravel, sand or forest paths, reduce the pressure to 2.0 to 2.2 atm. This will increase the tyre's contact spot with the surface and improve traction: 🔋 Reduced range by 10-15%; 🛡️ Increased risk of puncture; 💨 More frequent pressure checks (every 2-3 days).
Long trips (over 20 km).
On long routes, tires heat up and pressure rises. To avoid pumping, pump the wheels 0.2 atms less than the standard value. For example, instead of 2.8 atm, use 2.6 atms.
Aggressive driving style.
If you like to accelerate and brake abruptly, increase the pressure to 3.0-3.2 atm. This will improve handling, but make the ride harder. Be sure to check the condition of bearings and shock absorbers - they are under increased load.
For example, with reduced pressure, the risk of puncture increases 2-3 times, and with increased wear of bearings and forks increases.
💡
Optimal pressure is always a trade-off between comfort, safety and durability, and test different values regularly in safe conditions to find your perfect balance.
