Pressure in the wheels of the Xiaomi scooter: how many atmospheres to pump and how to do it correctly

Why is the right pressure in Xiaomi scooter tires so important?

Xiaomi scooters are some of the most popular vehicles in the city, but they require attention to trifles. One of the key is the pressure in the wheels. It affects not only the comfort of the ride, but also the safety, battery life, and wear of tires. Too low pressure increases the rolling resistance, making the engine run at its limit, and high pressure makes the trip hard and increases the risk of puncture.

Owners of Xiaomi M365, The Pro 2, Essential and other models are often faced with the question: how much atmospheres to pump into the wheels so that the scooter rides gently, but does not lose in dynamics? The manufacturer specifies the recommended values, but they can vary depending on the weight of the rider, the type of road surface and even weather conditions. In this article, we will discuss all the nuances - from the choice of a pressure gauge to step-by-step pumping instructions.

It's important to understand that the wrong pressure affects more than just driving performance, for example, when the pressure is reduced, the Xiaomi scooter begins to "suck" on corners, and when the wheels are over-inflated, the vibration from irregularities is transmitted to the steering wheel, which tires the hands. In addition, the mileage on one charge depends on the pressure - the difference can reach 10-15%!

Optimal pressure for different Xiaomi models: table of values

The manufacturer specifies standard pressure values for most models, but they can be adjusted. Below is a table with recommended parameters for popular Xiaomi scooters. All values are given in atmospheres (atm), which is equivalent to a bar (1 atm). ≈ 1 bar).

Note that for tubeless tire scooters (such as Xiaomi Air), the pressure should be lower, as such wheels are less elastic and do not require high pressure to maintain shape. It is also worth considering that the rear wheel (which accounts for the main load from the engine) can be pumped 0.2-0.3 atm stronger than the front.

⚠️ Warning: Exceeding the maximum pressure by more than 0.5 atm can cause the chamber to rupture or damage to the rim of the wheel.

How does the weight of a rider affect the pressure in the tires?

The manufacturer’s standard recommendations are designed for an average weight of a rider – about 70-80 kg. However, if your weight is significantly different, the pressure should be adjusted:

• 👶 Weight up to 60 kg: you can reduce the pressure by 0.3-0.5 atm from the recommended. This will make the trip softer, but make sure that the wheels do not “sank” when loaded.
• 🏋️ Weight 80-100 kg: increase pressure by 0.2-0.4 atm. This will prevent excessive wear of the tread and improve handling.
• 🏋️‍♂️ Weight over 100 kg: pump the wheels to the maximum permissible value (see table) or consider installing reinforced tires.

For an accurate calculation, the formula can be used:

Optimum pressure = Manufacturer's recommended + (Your weight in kg is 75) × 0.02 atm

For example, if you weigh 90 kg and ride a Xiaomi Pro 2 (recommended pressure of 4.0 atm), then:

4.0 + (90 - 75) × 0.02 = 4.0 + 0.3 = 4.3 atm

Step-by-step: how to pump the wheels of the Xiaomi scooter

To pump the wheels of the scooter you will need:

• 🔧 Pump with pressure gauge (bicycle or car with an adapter for a Presta or Shrader nipple).
• 📏 Manometer (if not in the pump) for precise pressure control.
• 🔑 Key to remove caps from nipples (usually comes complete with a scooter).
• 🧴 Lubricant for nipple (optional, if the cap is poorly unscrewed).

Now let's get to the pump:

1. Prepare the scooter: place it on a flat surface so that the wheels do not touch the ground. If the scooter was in the cold, let it heat up to room temperature (tyre pressure changes with temperature changes!).
2. Remove the caps from the nipples. Xiaomi scooters usually use Shrader-type nipples (like cars), but some models (like the Pro 2) may have Presta, a narrow bicycle nipple. Make sure your pump fits!
3. Connect the pump: snugly put the head of the pump on the nipple. If you hear hissing, then the connection is leaky, check the rubber gasket at the pump.
4. Pump the wheel, periodically checking the pressure with a pressure gauge. Pump in 0.5 atm portions so as not to pump.
5. Check the leaks: after pumping, moisten the nipple with soap solution. If bubbles appear, the air is poisoned somewhere (possibly damaged camera).
6. Twirl the caps back. Don't tighten them too much -- tight enough.

If you don't have a pump with a pressure gauge, you can use a bicycle pump or even a compressor at a gas station, but in this case, be careful: automatic compressors often pump the wheels. It is better to pump by hand, checking the pressure with a separate pressure gauge.

⚠️ Warning: Never pump the wheels of a Xiaomi scooter to pressures above 5.0 atm - this can cause the camera to explode.

Frequent mistakes in pumping wheels and how to avoid them

Even experienced riders sometimes make mistakes that shorten the life of the wheels or make handling worse.

• 🌡️ Pumping in the cold: if you are swinging wheels outside in temperatures below +10°C, the pressure inside the chamber will be lower than the pressure gauge indicates. If it gets into heat, the air will expand and the wheels will be pumped. Solution: pump indoors or adjust the pressure to the temperature (for every 10 hours).°C difference ≈ 0.1 atm).
• 🔧 Using an incompatible pump: Trying to pump a Presta nipple with a car pump without an adapter will damage the valve.Solution: buy a universal pump with a nipple type switch.
• 🚴 Ignoring the difference between the wheels: the rear wheel (with a motor) wears out faster, so it can be pumped 0.2-0.3 atm stronger than the front. Solution: keep a separate pressure record for each wheel.
• 💨 Eye pumping: even experienced riders can't accurately determine pressure without a pressure gauge.Solution: use a digital pressure gauge (costs 300) ₽) precisely.

Another common problem is the uneven wear of the tires, and if one wheel is constantly deflecting and the other is not, it can be:

• 🕳️ Micropuncture of the camera (you need to look for a leak with soap solution).
• 🔩 Poorly twisted nipple (check cap and valve).
• 🚗 Damaged rim (if the scooter often falls into pits).

💡

If the scooter wheel Xiaomi drops overnight, but there are no punctures, try lubricating the nipple with silicone lubrication. Often the air poisons through the valve, not through the camera.

How often do I check the pressure in the wheels?

Even if the wheels are not allowed to pass through air, the pressure in them gradually drops due to natural diffusion.

• 📅 Every 2 weeks with regular use (daily trips).
• 📅 Every month with rare skating (1-2 times a week).
• 📅 Before each trip, if the scooter was in the cold or heat (pressure varies with temperature changes).
• 📅 After heavy blows (for example, if you flew into a hole or curb).

It is also worth checking the pressure if you notice:

• 🛑 The scooter became "sluggish" and accelerates worse.
• 🛑 Increased battery consumption on the usual route.
• 🛑 There was a vibration or beating in the steering wheel.

For convenience, you can keep a pressure diary (for example, in notes on your phone), where you can record the date of the check and the pressure gauge for each wheel, which will help you track if one of the wheels starts poisoning the air.

Which pumps are best used for Xiaomi scooters?

Not every pump is suitable for pumping scooter wheels, here's what to look for when choosing:

For scooters Xiaomi is best suited pumps with:

• 🔹 Manometer (required!).
• 🔹 Support for Shrader and Presta nipples.
• 🔹 Maximum pressure up to 6-8 atm (in case you need to pump to the maximum).
• 🔹 Compact size (to take with you on trips).

If you’re a frequent rider, consider buying a portable electric pump — it takes up little space and pumps wheels in 1-2 minutes.For example, the Xiaomi Mi Electric Inflator weighs only 450g and is powered by Power Bank.

💡

For Xiaomi scooters, the best choice is a pump with a pressure gauge and support for a Shrader nipple. Electric models are convenient for frequent trips, but manual ones control pressure more accurately.
