The Xiaomi M365 remains one of the most popular vehicles in the city, but its reliability and comfort are directly dependent on the condition of the wheels. One key parameter that owners often ignore is tire pressure. Insufficient or excessive pumping not only impairs handling, but also reduces the life of the tires, and in some cases even leads to accidents.
In this article, we will look at how many atmospheres should be in the tires Xiaomi M365 according to the manufacturer’s recommendations, how to measure pressure, what factors affect its change, and what will happen if you ignore these rules, you will also find practical tips for caring for wheels, a table of compliance with the pressure of the weight of the rider and answers to frequent questions.
Xiaomi’s official recommendations for M365 tire pressure
Xiaomi says in the instructions for the M365 that the optimum tire pressure is 35-50 PSI (equivalent to 2.4-3.5 bar or atmospheres), but this range is quite wide, and many owners are not sure what value to choose for their operating conditions.
It is important to understand that the recommended pressure is a trade-off between comfort, safety and wear.
- 🔹 35–40 PSI (2.4-2.8 bar) - soft driving, better cushioning on irregularities, but higher risk of puncture and rapid wear.
- 🔹 45–50 PSI (3.2-3.5 bar) – maximum energy efficiency and puncture protection, but hard driving, especially on bad roads.
In most cases, 40-45 PSI (2.8-3.1 bar) pressure is considered optimal, as it balances comfort and durability, but the final choice depends on the weight of the rider, the style of the ride and the quality of the road surface.
How the weight of a rider affects the pressure in tires
One key factor that is often overlooked is the weight of the person driving the scooter. The heavier the rider, the higher the pressure must be to prevent the tire from deforming and overheating.
| Rider weight (kg) | Recommended pressure (bar/atm) | Recommended pressure (PSI) |
|---|---|---|
| Up to 60kg | 2.4–2.8 | 35–40 |
| 60-80 kg | 2.8–3.1 | 40–45 |
| 80-100 kg | 3.1–3.4 | 45–50 |
| Over 100 kg | 3.4 to 3.5 (maximum) | 50 (maximum) |
If you weigh more than 100 kg, you should consider installing reinforced tires (for example, Xiaomi M365 Pro or tubeless tires), as standard M365 wheels are not designed for such loads and wear out faster.
⚠️ Warning: When riding with a passenger or cargo, the tire pressure should be increased by 0.3–0.5 bar relative to your weight.Exceeding the maximum pressure (3.5 bar) can cause the tire to rupture!
How to measure and pump tires correctly
To accurately monitor the pressure, you will need a pressure gauge (preferably a digital one, since mechanical ones often lie), and you need to measure the pressure with cold tires - after the trip, the tires heat up, and the readings will be inflated by 0.2-0.5 bar.
Step-by-step:
Remove the cap from the nipple (usually hidden under a plastic cap).
Connect the pump with a pressure gauge to a nipple (the M365 uses a standard Presta or Schrader bicycle nipple - check in the instructions).
Pump to the desired pressure, periodically checking the pressure gauge.
Close the nipple with a cap to avoid dirt.
Check the pressure in 10-15 minutes (possible leakage through the stool).-->
If you don't have a pump with a pressure gauge, you can use a compact bicycle pump or go to a bike master's.Some owners use car compressors, but they often pump tires, so you have to be careful.
💡
If the scooter becomes less manageable after pumping (for example, it walks along the road), check the uniformity of the pressure in both wheels. A difference of more than 0.3 bar can lead to a sideways withdrawal.
Consequences of improper tyre pressure
Many Xiaomi M365 owners do not pay due attention to tire pressure, which leads to serious problems.
Pressure is too low (less than 2.4 bar):
- 🚨 Increased risk of puncture – soft tires are easier to break through with sharp objects.
- 🔋 Fast battery discharge – scooter spends more energy overcoming resistance.
- 🛞 Accelerated tread wear - the side parts of the tire are worn unevenly.
- 😵 Poor handling – the scooter “floats” on corners, especially at high speed.
High pressure (over 3.5 bar):
- 💥 Risk of tire rupture – especially when hitting a curb or pit.
- 😖 Hard driving – all the roughness of the road is transmitted to the hands and feet.
- 🛑 Deterioration of traction – smaller area of contact with the road reduces the braking distance.
- 🔧 Rim damage - with a strong impact, the tire does not cushion, and the impact falls on the disc.
⚠️ Warning: If you notice that the scooter has started to wag in a straight line or brakes worse than usual, first check the pressure in the tires. In 70% of cases, the problem is solved by a simple pumping!
Frequent mistakes in the pumping of Xiaomi M365 tires
Even experienced scooters sometimes make mistakes that shorten the life of the wheels, and here are the most common ones:
- 🔧 Using an inappropriate pump – some car compressors are not compatible with nipples M365 (You need an adapter for Presta).
- ❄️ Measurement of pressure on hot tires - after the trip, the tires heat up, and the pressure gauge will show an overestimated value.
- 🚫 Ignoring slow leakage – if the tires are lowered overnight, the problem may be a spool or puncture.
- ⚖️ Uneven pumping of wheels - different pressure leads to the scooter sideways.
- 🔩 Tightening the nipple cap with force - this can damage the spool and cause leakage.
One of the most dangerous mistakes is to use a sealant instead of a puncture repair. Many owners put a puncture gel in their tires (like Slime), but this is a temporary solution. The sealant eventually dries out, clumps up, and can clog the nipple, and if the tire is broken, it's better to replace it or repair it in the workshop.

How often to check the pressure in the tires
The manufacturer recommends that the pressure be checked every 2 weeks, but in practice the frequency depends on the intensity of use:
- 🏙️ Daily driving in the city - once a week.
- 🚲 Rare trips (1-2 times a week) - once every 2-3 weeks.
- ❄️ Winter operation - before each trip (cold reduces pressure).
- 🔥 Summer heat - every 5-7 days (pressure increases with heating).
The pressure should also be checked in the following cases:
- 🛣️ After a long trip (more than 20 km).
- 💥 After hitting a curb or a pit.
- ⚡ If the scooter began to accelerate worse or "sucks" during braking.
💡
Even if the tyres look normal visually, it doesn't mean the pressure is normal.The Xiaomi M365 tires can lose up to 0.1-0.2 bar per week due to natural leakage through the camera.
Tips for extending the life of tyres
The right pressure is only part of the maintenance of the wheels, so that the tires last longer, follow these recommendations:
- 🛠️ Regularly inspect the tread for cuts, stuck stones or glass.
- 🚗 Avoid riding on gravel and broken glass - this is the main cause of punctures.
- 🔄 Periodically change the wheels in places (front / back) so that they wear evenly.
- 🧴 Use a special lubricant for the nipples so that they do not boil or let air pass.
- 🛑 Do not brake sharply at high speed - this leads to tire crumbs.
If you're on bad roads often, consider installing tubeless tires (such as the Xiaomi M365 Pro or Ninebot Max) that are less prone to punctures and hold pressure longer, but are harder to repair and more expensive than standard tires.
Another useful accessory is wheel safety inserts (such as Honeycomb), which prevent punctures and increase the stiffness of the tire, but slightly worsen cushioning.
