Owning a Xiaomi electric scooter requires regular maintenance, and one of the most critical parameters is tire pressure, which many users ignore before the first problems with mileage or the appearance of “eights” on the disks. Optimal pressure directly affects not only the comfort of the trip, but also the safety of the driver, as well as the life of the battery.
Incorrectly inflated tires can lead to rapid tread wear, reduced top speed and increased power consumption. In this article, we will discuss in detail what the atmospheric values are reference for different models of the brand, how often you need to check this parameter and why electronic pressure gauges can give an error.
Optimal pressure indicators for different models
Xiaomi makes specific recommendations for each series of devices, but there is a universal rule for most models with wheels with diameters of 8.5 and 10 inches. The standard value for urban models such as the M365 or Pro 2 is the range from 3.5 to 4.5 atmospheres (Bar).
For more powerful versions, such as the Xiaomi Electric Scooter 4 Pro or Ultra, the requirements may vary slightly depending on the weight of the rider and the type of road surface.If you weigh more than 90 kg, it is recommended to keep the pressure closer to the upper limit of normal to avoid camera breakdown and rim deformation when hitting roughness.
⚠️ Note: Do not exceed the maximum value of 4.5 atmospheres (65). PSI) on standard cameras, as this can cause rubber to rupture or tyre bloating on the disc.
It's important to understand that the nominal pressure is not a static number. When you're driving and frictioning on the road surface, the air inside the chamber heats up and expands, which can briefly increase the gauge reading, so it's recommended to check and pump the wheels exclusively on the "cold" when the scooter stood motionless for several hours.
Table of pressure standards depending on model and weight
For the convenience of users, we have organized the data into a single table, which will help you quickly navigate if you do not remember the exact specifications for your modification of electric vehicles. Note that the values are given in atmospheres (Bar), since this is the scale most often used on household compressors.
| Model scooter | Diameter of wheels | Recommended pressure (Bar) | Maximum pressure (PSI) |
|---|---|---|---|
| Xiaomi M365 / Pro | 8.5 inches | 3.5 - 4.0 | 65 |
| Xiaomi 1S / Essential | 8.5 inches | 3.5 - 4.0 | 65 |
| Xiaomi Pro 2 / Pro 3 | 10 inches | 4.0 - 4.5 | 70 |
| Xiaomi Ultra / 4 Pro Max | 10 inches | 4.0 - 4.5 | 70 |
The data in the table is averaged and suitable for standard operating conditions. If you use a scooter in winter or on poor asphalt, the values can be adjusted. Winter tires or special all-season tires often require slightly less pressure for better traction, but do not fall below 3.0 Bar, otherwise the risk of puncture increases.
Effect of pressure on mileage and acceleration dynamics
Many riders wonder why their gadget travels fewer kilometers than the manufacturer claims. Often it is the flat tires that cause it. Lack of pressure increases the area of contact between the tire and the road, which leads to an increase in rolling resistance. The engine has to work harder, consuming more energy from the battery to maintain the same speed.
On the other hand, pumped wheels make driving stiff and uncomfortable, especially on pavers. However, in terms of dynamics and range, high pressure (within reasonable limits) is always preferable. At 4.0-4.5 Bar, the scooter accelerates more easily and retains inertia for longer when coasting.
💡
Check the pressure before each long trip, even a small difference of 0.5 atmosphere can reduce the actual mileage of the scooter by up to 15%.
The better to pump: pumps, compressors and accessories
There are several types of devices available for Xiaomi’s wheel maintenance, each with its own advantages. The standard mechanical pump that comes with some models requires a lot of physical effort to reach 4 atmospheres, especially if you need to pump two wheels at once.
The most convenient solution is an electric portable compressor, such as the Xiaomi Portable Electric Air Compressor, which allows you to set the exact pressure value on the digital display and automatically turn off when you reach the goal, this eliminates the risk of pumping and saves the owner time.
☑️ What you need to do for the right pumping
It is also important to consider the type of nipple. Xiaomi scooters usually use car nipples like Schrader, but in some versions or when changing cameras, Presta bicycles may be found. Make sure your pump is compatible with the type installed, or use an adapter.
How to measure and pump the wheels correctly
The paging process is simple, but it has its own technical nuances, ignoring which can lead to inaccurate results. The first thing you need to do is to unscrew the protective cap from the nipple and check its integrity. If the cap is lost, it is advisable to install a new one so that dust and moisture do not get inside.
Then you have to connect the pump or compressor hose, and if you press the lock lever, you'll hear a characteristic hissing sound, which is the extra air coming out of the adapter, and at that point the pressure gauge readings may be incorrect, so you need to start counting the pressure after the connection is sealed.
The Secret to Accurate Measurement
⚠️ Attention: When the pump hose is disconnected, there is always a slight loss of air. 0.1-0.2 atmosphere, so that after the detachment of the hose, the value returns to normal.
Frequent Mistakes and Myths About Tire Maintenance
There is a common misconception that the less pressure, the softer and more comfortable the ride. Yes, cushioning improves, but the risk of snakebite — camera failure on the rim when hitting an obstacle — becomes sharper, and low pressure also causes uneven wear of the sidewalls of the tire and can cause it to rupture.
Another myth is that you can put a sealant in a tubeless tire and forget about the checks forever. Seal gels do help to fix small punctures, but they eventually dry out and lose their properties. In addition, the presence of a gel inside can disrupt the balance of the wheel, causing the steering wheel to beat at high speeds.
💡
The golden rule: Keep the pressure at 3.8-4.2 Bar all year round, adjusting values only at extremely low temperatures or very high weight rider.
Seasonal features and temperature regime
The laws of physics say that when you change the temperature, the volume of gas changes, and in the summer, in hot weather, the pressure in the wheels can spontaneously increase. If you keep a scooter in a warm room and go out in the sun, the pressure gauge can jump to critical values, in which case it is recommended to put excess air before the trip.
In winter, the opposite is true: in the cold, the air shrinks and the pressure drops. If you pump the wheels to 4.0 atmospheres in a warm garage at +20°C, outside at -10°C, the pressure can drop to 3.2-3.4 atmospheres, which should be considered when preparing for winter operation.
