Xiaomi electric scooter tire pressure: how many atmospheres to pump for safety and durability

Xiaomi scooters are some of the most popular vehicles in the city, but their reliability depends on proper care. One of the key parameters that many owners miss is tire pressure, which affects not only ride comfort, but also battery life (up to 15% of the difference in mileage on a single charge), tire wear and even wet road safety. In this article, we will discuss how much atmosphere you need to pump in the wheels of the Xiaomi M365, Pro 2, 4 Pro, Electric Scooter 3/4 Lite and other models, and how to go wrong.

The manufacturer lists recommended pressures in the technical documentation, but these data are often lost or ignored. Meanwhile, underperforming tires increase rolling resistance and reduce mileage by 10-20%, and overpumped tires make driving tough and increase the risk of puncture. We collected current data for all modern Xiaomi models, including rare versions, and added practical tips for checking and adjusting pressure.

Xiaomi’s official tire pressure recommendations

Xiaomi in the instructions for electric scooters indicates the pressure range for the front and rear wheels.

• 🔋 Weight of the scooter (usually 12-15 kg excluding the rider).
• 👤 Maximum load (up to 100-120 kg for most models).
• 🛞 Type of tires (cameraless or chamber, diameter 8.5-10 inches).
• 🚀 Optimal balance between grip and energy efficiency.

Important: Pressure is measured in atmospheres (atms), but some pressure gauges show values in PSI (pounds per square inch) or bar (1 bar ≈ 1 atm). For translation, use the formula: 1 atm = 14.5 PSI. For example, the recommended 2.5 atm = 36.25 PSI.

Pressure table on Xiaomi models (2020-2026)

⚠️ Note: For models with puncture-resistant tires (for example, Xiaomi Pro 2 with self-sealing gel), a pressure reduction of 0.2-0.3 atm from the upper limit is allowed. This compensates for the stiffness of the tire, but requires more frequent inspection (every 2 weeks).

How to measure pressure correctly: step-by-step instructions

To check the pressure, you'll need a bicycle or a car pressure gauge with an accuracy of 0.1 atm. Cheap plastic pressure gauges are often lying at ±0.3 atm - it's better to use digital or mechanical with a metal body.

Remove the caps from the nipples (if any)

Connect the pressure gauge to the nipple and fix

Reset the readings of the device (if there is a zero button)

Check the pressure on cold tires (at least 2 hours after driving)-->

If the pressure is below normal:

1. Connect the pump to the nipple (a standard Schrader bicycle nipple is suitable for Xiaomi).
2. Pump short pulses of 5-10 seconds, periodically checking with a gauge.
3. Stop pumping when the value reaches the lower limit of the recommended range (e.g., 2.3 atm for Pro 2).
4. Check the pressure after 10 minutes - the air in the tire heats up during pumping and may show an overestimated value.

💡 Useful advice: If you do not have a pressure gauge, use a contactless method: press hard on the tire with your thumb. At the right pressure, the tire should bend no more than 2-3 mm. However, this method is subjective and only suitable for approximate assessment.

Consequences of improper pressure: what will happen if you pump or under-pump

Deviating from the recommended values even by 0.5 atm can lead to serious problems.

🔴 Unproven tyres (<1.8 atm)

• 🔋 15-25% reduction in mileage due to increased rolling resistance.
• 🛞 Accelerated tread wear at the edges (tyres are “smeared” when cornering).
• 💦 The risk of aquaplaning on a wet road - water does not have time to be pushed out from under the wheel.
• 🚨 Rim damage when falling into a pit (tyres do not cushion impact).

🟢 Over-inflated tyres (>3.5 atm)

• 🦵 Hard driving - all irregularities are transmitted to the hands and feet, the vibration increases.
• 💥 Increased risk of puncture – the tire becomes thinner and more vulnerable to sharp objects.
• 🛑 Deterioration of traction with the road (less contact area).
• 🔧 Load on bearings and wheel sleeve due to reduced depreciation.

⚠️ Note: If you notice that Xiaomi tires flatten 1-2 days after pumping, this is a sign of damage to the camera or nipple.In 80% of cases, the problem is solved by replacing the nipple reverse valve (costs) ~100 rubles, but sometimes a full replacement of the camera is required.

Pressure check frequency: when and how often to pump wheels

Even under ideal conditions, Xiaomi tires lose ~0.1–0.2 atm per month due to micropores in rubber.

• 📅 Every 2 weeks – for daily use.
• 🏠 Before the long trip (>10 km) or after a month's downtime.
• ☀️ With sudden changes in temperature (for example, autumn)→Cold reduces pressure by 0.1-0.3 atm.
• 🚗 After transportation in the trunk - vibration can knock down a nipple.

🔹 Seasonal adjustments:

In winter (+5°C and below), tire pressure drops by 10–15% due to physical air compression. If you pump 2.5 atms in summer, this will drop to ~2.1 atms in winter. To compensate for the effect, pump the wheels 0.2–0.3 atms above the recommended in summer. For example, for the Xiaomi Pro 2 in winter, 2.8–3.0 atms are optimal.

💡

Use winter tread tires (such as Xiaomi Winter Tires) below +7°C, which retain elasticity and grip.

Choosing a pump for Xiaomi electric scooter

Not every pump is suitable for pumping Xiaomi wheels.

• 🔌 The type of nipple is Schrader only (car). Presta (bicycle thin) doesn't fit!
• 📏 Maximum pressure - at least 4 atm (most cyclone pumps are limited to 3 atm).
• 🔋 Manometer - mandatory for accurate adjustment.
• 🚲 Compact – it is better to choose a pump with a folding handle (for example, Xiaomi Portable Electric Air Pump).

🔹 Top.-3 pumping:

1. Xiaomi Mi Portable Electric Air Pump – automatically pumps to a given pressure (supports up to 150 PSI), works from Power Bank.
2. Decathlon B’Twin 500 – mechanical pump with an accurate manometer, budget version (~ 1000 rubles).
3. Lezyne Sport Drive HP is a premium pump with an aluminum body, suitable for high pressure.

⚠️ Warning: Do not use car compressors without a pressure limiter! They can pump the tire in seconds (up to 6-8 atm), which will cause the tire to rupture. If you have to use a compressor, pump in pulses for 1 second with constant pressure gauge control.

Frequent mistakes in the pumping of Xiaomi tires

Even experienced scooters make mistakes that shorten the life of wheels.

• 🌡️ Measurement of pressure on hot tires (immediately after driving). The air inside heats up, and the pressure gauge will show an inflated value of 0.3-0.5 atm. Always wait 2-3 hours.
• 🔧 Using a sealant without checking a nipple. If the tires are coming down because of a faulty valve, the sealant won't help, you need to replace the nipple.
• ❄️ Storage of the scooter in winter with the tires pumped up. In sub-zero temperatures, the rubber tans and the pressure can exceed the strength limit. In winter, lower the wheels to 1.5-1.8 atm.
• 🛠️ Self-repairing tubeless tires without special equipment, without a crimping machine, you can't evenly glue the patch.

💡 If you often drive on gravel or construction sites, install anti-puncture inserts (for example, Tannus Armour) that protect the camera from sharp objects and reduce pressure by 0.2-0.3 atm without the risk of puncture.
