Why is the pressure in the tires of the Xiaomi electric scooter is critical?
Have you ever wondered why your Xiaomi M365 or Pro 2 suddenly gets worse at driving, discharges faster, or makes weird noises when driving? 90% of the time, the problem is the wrong wheel pressure. It's not just a technical detail, it's a safety, battery life, and even the legality of using a scooter in some countries.
The manufacturer clearly regulates the pressure standards for each model, but many users either ignore these recommendations or simply do not know how to measure and adjust the pressure. Meanwhile, even a deviation of 0.2 atmosphere can lead to an increase in energy consumption by 10-15%, and if a severe failure of the pump, the risk of puncture or βsnake biteβ (double puncture of the camera) increases by 3 times. In this article, we will analyze the exact pressure values for all popular Xiaomi models (including the new 2026 years), learn how to check it without a gauge and tell what mistakes 95% of owners make.
Official pressure standards for all Xiaomi models (Table 2026)
Xiaomi lists the recommended wheel pressure for each model in the technical documentation, but this data is often lost or ignored. Below is an updated table with the latest updates from the manufacturer (this is confirmed by Xiaomi service centers in Russia and Europe).
| Model scooter | Wheel size | Recommended pressure (atm/bar) | Maximum pressure (atm) | Type of tire |
|---|---|---|---|---|
| Xiaomi M365 (2016-2020) | 8.5" | 3.5β4.0 | 4.5 | Pneumatic (chamber) |
| Xiaomi Pro 1/Pro 2 | 8.5" | 3.8β4.2 | 4.8 | Pneumatic (chamber) |
| Xiaomi Essential | 8.5" | 3.5β4.0 | 4.5 | Pneumatic (chamber) |
| Xiaomi 1S / Pro 2 (2021+) | 8.5" | 4.0β4.3 | 5.0 | Pneumatic (chamberless) |
| Xiaomi 4 / 4 Pro | 10" | 2.8β3.2 | 3.5 | Pneumatic (chamberless) |
| Xiaomi Air 125 | 12.5" | 2.5β2.8 | 3.0 | Pneumatic (chamberless) |
β οΈ Attention: The data in the table are for cold wheels (the scooter was not used for at least 2 hours). When driving actively, the pressure can increase by 0.3-0.5 atm due to the heating of the air inside the tire. Do not deflate immediately after the trip, wait for cooling!
For models with tubeless tires (for example, Xiaomi 1S or 4 Pro) allowed the upper limit of normal (for example, 4.3 atm instead of 4.0), because the risk of puncture is lower. However, to exceed the maximum value (5.0 atm for 8.5" wheels) strictly not β this can lead to rupture of the side of the tire.
How to check the pressure: 3 working methods (with and without a pressure gauge)
Check the pressure in the wheels of the scooter at least once every 2 weeks (or before each long trip).
- π Digital pressure gauge (inaccuracy) Β±0.1 atm: the most accurate way. Connects to the wheel nipple, shows the current pressure on the screen. Costs from 300 rubles (for example, Xiaomi Mijia Tire Pressure Gauge).
- π§ Mechanical gauge (inaccuracy) Β±0.2 Atm: cheap and reliable. It is important to choose a model with a scale of up to 5-6 atm, since standard car pressure gauges often do not show values below 1.5 atm.
- π "Manual testβ (inaccuracy) Β±0.5 atm: press your thumb on the tire. If it bends more than 5 mm, the pressure is below normal. If it barely pushes, it may be pumped. The method works only for advanced users!
πΉ Step-by-step instruction with a manometer:
- Remove the protective cap from the wheel nipple.
- Press the pressure gauge tightly against the nipple (short air bursts should be heard).
- Wait 2-3 seconds for the arrow or numbers on the screen to stabilize.
- Compare the readings with the table above.
- If the pressure is below normal, pump the pump. If higher, blow the air by pressing the pin of a nipple (for example, the back of the cap).

Check the pressure gauge for operability (press reset) |
Make sure the wheel is cold (not driven 2)+ hour)|
Prepare the pump or compressor (if required)-->
β οΈ Warning: Never use a car compressor to pump the wheels of a scooter at a gas station! They supply high-pressure air (often 6 atm) and can instantly tear the camera. Use only hand-held bicycle pumps or special electric pressure-adjusted pumps (e.g. Xiaomi Portable Electric Air Pump).
What happens if you pump the wheels wrong? 5 real consequences
Many scooters treat tire pressure as a trifle, but in practice, it affects everything from ride comfort to safety. Here are the specific problems you'll face when you're off the mark:
- π 15-30% reduction in range: at a pressure below 3.0 atm (for 8.5" wheels), the scooter spends more energy on overcoming resistance. M365 with half-deflated wheels will travel not 30 km, but only 20-22 km on one charge.
- π¨ Risk of puncture or snake bite: at pressures below 2.5 atm, the camera deforms and can pinch between the rim and the road, leading to a double puncture).
- π Deterioration of braking and handling: over-pumped wheels (above 4.5 atm) lose traction, especially on wet pavement. Brakeway increases by 20-40%.
- π Increased noise and vibration: at a pressure above 4.2 atm, the scooter begins to "jump" on irregularities, and bearings and shock absorbers wear out 2 times faster.
- βοΈ Problems with the law: in some countries (for example, Germany or France) riding a scooter with a pressure below normal is equivalent to driving a faulty vehicle and is punishable by a fine of up to 50 euros.
What is a βsnake biteβ and how to avoid it?
π‘ If you often drive on bad roads (gravel, pits), you can slightly reduce the pressure by 0.2-0.3 atm from normal, this will improve cushioning, but increase the risk of puncture. A compromise option is to use gel cameras (for example, Tannus Armour), which are not afraid of punctures and allow you to drive with a pressure of 2.5-3.0 atm without risk.
How often do I check and adjust my blood pressure?
Even if you don't use a scooter, the pressure in the wheels gradually decreases because of the micropores in the rubber, and here are the optimal intervals for checking:
- π Active use (driving every day): check the pressure every 3-5 days. Pump up when falling 0.3 atm from normal.
- π Rare use (1β2 times a week): checks every 2 weeks are enough.
- βοΈ Winter: pressure drops by 0.1β0.2 atm with a decrease in temperature for every 10Β°C. Check before each trip!
- βοΈ Summer period: at temperatures higher +25Β°C pressure can rise by 0.2-0.3 atm. blow the excess air if the value exceeds the maximum.
πΉ When an urgent inspection is required?
- After hitting a curb or a hole.
- If the scooter has become "heavy" or worse accelerated.
- When there is a noise, there is a noise.
- Before a long trip (more than 10 km).
π‘
Even if the wheel looked normal, the pressure could drop by 0.5-1.0 atm without any visible signs, and regular pressure gauges are the only reliable way to monitor it.
Top.-5 Mistakes in Wheel Pumping (and How to Avoid Them)
Experience from service centers shows that 80% of problems with Xiaomi scootersβ wheels are caused by elementary pumping errors, and the most common ones are:
- Using the wrong pump: Car compressors or pumps without a pressure gauge often pump the wheels. Solution: use a bicycle pump with a pressure gauge or a special electric one (for example, Xiaomi Mi Electric Pump).
- Pumping "by eye": even experienced riders make a mistake by Β±0.5 atm. Solution: always use a pressure gauge, even for a "quick" check.
- Ignoring temperature: The pressure changes when you heat up/cool down. Solution: pump the wheels in the shade and let the scooter cool down after the ride.
- Forgetting about the rear wheel: many people only check the front wheel, and the rear wheel remains half-deflated. Solution: check both wheels, even if they look the same on the outside.
- Improper storage: if you leave the scooter in the cold with the wheels pumped, the pressure will fall, and the rubber can crack. Solution: for the winter, reduce the pressure to 2.0-2.5 atm and store in a cool place (at least + 5 Β° C).
β οΈ Note: If you use a tire sealant (such as Slime), remember that it can dry up during long downtime. Shake it before pumping it so that the sealant is evenly distributed throughout the chamber. If the pressure drops faster than usual (more than 0.5 atm per week), this is a sign that the sealant has lost its properties and needs to be replaced.
