How many atmospheres to pump in the wheels of the Xiaomi electric scooter: a complete guide to 2026

Xiaomi scooters are some of the most popular vehicles in the city, but they require attention to trifles. One of the key ones is the pressure in the wheels. It affects not only the comfort of the ride, but also the safety, battery life, and wear of the tires. Many owners ask, "How much atmospheres can you pump in the wheels of the Xiaomi Scooter to avoid damaging the equipment?"

In this article, we will analyze the official recommendations for all current models (from M365 to 4 Ultra), explain how to measure pressure, what is the risk of pumping or under-pumping, and give advice on the choice of pumps and frequency of inspection.

If you've just bought a scooter, or you notice it's getting worse, don't be quick to blame the battery. In 70 percent of cases, the problem is with the wheels. Let's get it straight.

Official pressure standards for Xiaomi models

The manufacturer indicates the recommended tire pressure for each model in the instructions for use, these values are calculated taking into account the weight of the scooter, the maximum load and the characteristics of the tires. Below is the current table for popular Xiaomi models (data for 2026):

Note that scooters with 10 inches (like the 4 Pro) are generally less pressurized than 8.5-inch models, due to the greater contact area of the tire and the distribution of load.

⚠️ Note: If your scooter is equipped with tubeless tires (for example, Xiaomi Air 12), the pressure should be 0.2-0.3 atm above these values due to the design features.

Not sure about the model? Check the markings on the frame or in the Mi Home mobile app (Device → Information section). If your model is not in the table, focus on the similar characteristics (for example, for Essential, M365) will work.

What is the danger of improper pumping of wheels?

A deviation from the recommended values even by 0.5 atm can lead to serious consequences.

• 🔴 Over-pumped wheels (above normal): Reduced spot of contact with the road → The grip is worse, especially on wet pavement, and the load on bearings and shock absorbers increases. → rapid wear and tear: Risk of tire explosion when hitting an obstacle (e.g. curb).
• 🟡 Unproven wheels (below normal): Increased rolling resistance → 1 charge mileage reduction to 15%. tire sidebars wear out faster → Risk of hernia. Controlling is worse: the scooter swims at high speeds.

💡 Example from practice: the owner of Xiaomi Pro 2 rolled with a pressure of 2.8 atm instead of the recommended 4.0. After 3 months, the tire burst on the bump, and the mileage on one charge decreased from 30 km to 22 km.

⚠️ If you weigh more than 90 kg, add to the recommended pressure. +0.3 atm For weights over 110 kg — +0.5 atm. That compensates for the increased load on the wheels.

💡

Before a long trip (more than 20 km), check the pressure with a pressure gauge - when the tire is heated, the pressure can increase by 0.2-0.3 atm.

How to measure pressure correctly?

For accurate measurement, you will need a pressure gauge (built into the pump or separate).

1. Cool the wheels. Measure the pressure no earlier than 2 hours after the trip (or drive 1-2 km at low speed).
2. Remove the protective cap from the nipple (it prevents dirt from getting in).
3. Tightly attach the pressure gauge to the nipple. Xiaomi uses the standard car nipple Schrader.
4. If the pressure gauge is electronic, wait for the stable value.
5. If necessary, pump or blow air, then repeat the measurement.

❌ Measurement errors:

• 🚫 Use of cheap plastic pressure gauges (accuracy to the ±0.5 atm).
• 🚫 Measured by eye (by pressing a finger on the tire).
• 🚫 Measurement immediately after driving (pressure will be overestimated due to heating).

🔧 Tip: Buy a compact pump with a built-in pressure gauge (e.g. Xiaomi Mi Portable Electric Air Compressor) that shows real-time pressure and automatically shuts down when a given value is reached.

Make sure the wheel is cooled |

Check the nipple for damage |

Use a precise gauge (accuracy ≤0.1 atm)|

How often do I check my blood pressure?

Even if the wheels look normal visually, pressure may drop due to micropores in the rubber or a leaky nupple.

• 📅 Weekly – if you are riding daily.
• 📅 Before each trip – if the scooter stood for more than a week without use.
• 📅 After a sharp temperature change (for example, autumn)→In winter, it's 10 times colder.°C pressure drops ~0.1 atm.
• 📅 After hitting sharp objects (glasses, nails) or strong blows (kerbs, pits).

🔄 Seasonal adjustments:

• 🌞 Summer: You can reduce pressure by 0.1-0.2 atm for better grip on hot asphalt.
• ❄️ Winter: Increase pressure by 0.2–0.3 atm (cold air shrinks and actual pressure drops).

⚠️ Warning: If the pressure drops faster than 0.3 atm in a week, look for a puncture or a faulty nipple. Check the wheel in the bathtub with water (air bubbles will appear) or apply soap solution to the nipple.

Which pump to choose for Xiaomi Scooter?

Not all pumps are suitable for pumping scooters, but here are the key requirements:

• 🔌 Nipple type: Must support Schrader (car) Most bicycle pumps work with Presta - they won't work without an adapter.
• 📏 Max pressure: At least 6-8 atm (even if you need 4 atm, you need a margin for precise adjustment).
• ⚡ Type of pump: 🚲 Manual: Compact but requires effort (e.g. Xiaomi Mi Pump). ⚡ Electric: Pumps quickly to the desired pressure (e.g. Black)+Decker ASI300). 🔋 Battery portable: Comfortable to take on a trip (e.g. AstroAI) ATG150).

💰 Budget options (up to 1500) ₽):

• 🛒 Xiaomi Mi Pump (manual, with a pressure gauge).
• 🛒 Decathlon B'Twin 500 (feather, versatile).

💎 Premium options (from 3000) ₽):

• 🛒 Lezyne Digital Pressure Drive (Digital Manometer, Error) ±0.05 atm).
• 🛒 Ryobi R18I-0 (battery, 18V).

❌ What to avoid:

• 🚫 Cheap plastic pumps without a pressure gauge.
• 🚫 Pumps with a maximum pressure of less than 5 atm.
• 🚫 Car compressors without pressure adjustment (can be pumped).

What to do if the wheel is running down?

If the pressure drops faster than normal, follow the algorithm:

1. Find the leak site: Submerge the wheel in water (bath, bucket) - the bubbles will indicate a puncture. Apply soap solution on the nipple and sidewalls of the tire.
2. Determine the type of damage: 🔪 Puncture: Sharp object (nail, glass). 🌀 Cut: Torn rubber (for example, after hitting the rebar). 🔧 Faulty nipple: Cracks on the body or wear of the valve.

Fix the problem:

• 🩹 Puncture up to 2mm: Use a tubeless tire repair kit (e.g. Slime Smart Spair).
• 🔧 Cut or large puncture: Replacement of the tire or camera is required.
• 🔄 Faulty nipple: Replace it (cost) ~200 ₽).

⚠️ Warning: If the wheel is deflating due to a crack on the rim (for example, after a heavy impact), repair is useless - you need to replace the entire wheel.

💡 Temporary solution: If you puncture on the road, use a tire sealer (such as the Hi-Gear Tire Doctor) that will seal the hole for 1-2 weeks, but does not replace a full repair.

💡

If the scooter is used for extreme driving (jumping, aggressive braking), check the pressure and condition of the wheels after each trip.

Myths and misconceptions about pressure in wheels

There are a lot of tips on the Internet that are not only useless, but also harmful.

• 🚫 "The more pressure, the faster the scooter travels" Reality: At pressures above 5 atm, rolling resistance does drop, but the grip worsens and the risk of puncture increases.
• 🚫 "You can pump to the maximum indicated on the tire" Reality: Maximum pressure (e.g. 6-7 atm) is the strength limit, not the operating value. Excess leads to premature wear and tear.
• 🚫 "Summer and winter pressure should be the same" Reality: When the temperature changes by 10°C pressure changes to ~0.1 Atm: In winter it should be increased, in summer - reduced.
• 🚫 "If the wheel does not come down, you do not need to check the pressure" Reality: even new tires lose ~0.1 atm per month due to air diffusion through rubber.

📊 Experiment: Owner Xiaomi 4 Pro tested driving with pressures of 3.0, 4.0 and 5.0 atm:

• 3.0 atm: run 28 km, poor handling at speed > 25 km / h.
• 4.0 atm: 32 km mileage, optimal grip.
• 5.0 atm: 33 km mileage, but vibrations on the steering wheel and risk of puncture.
