How to properly put a tire on a Xiaomi scooter: from the choice of rubber to the finish balancing

Replacing the tire on the Xiaomi electric scooter is a task that scares beginners, but in fact requires only accuracy and the right tools. 7 out of 10 owners of scooters face punctures or wear of rubber in the first 12 months of operation, and the service costs 1500-3000 rubles - despite the fact that self-replacement will cost 3-5 times cheaper. In this article, we will examine not only the step-by-step process of installing a tire, but also the criteria for choosing a rubber, common errors (for example, why 90% of users incorrectly set the direction of rotation of the wheel), as well as nuances for specific models - from Xiaomi M365 to Pro 3.

It is important to understand that the procedure is different for wheels with cameras and tubeless tires, and also depends on the type of rim (solid or spoke).We will focus on the most common version, the 8.5-inch chamber wheels that are on most Xiaomi scooters. If your model is equipped with tubeless tires (for example, Xiaomi Electric Scooter 4 Pro), the process will be more complicated - you will need a special sealant and compressor.

Before you start, check:

• 🔧 Tools: tire-mounting levers (minimum 2 pcs), pressure pump, wheel-removal keys (usually T25 and 10 mm), scissors or screed cutters.
• 🛒 Consumers: new tire (compatible with your model!), camera (if you need a replacement), zip-ties for fixing cables.
• 📏 Wheel parameters: diameter (8.5" or 10"), width (2.125" or 2.5"), tread type (slick, half-slick, mud).

1. How to choose a tire for a Xiaomi scooter: 5 criteria

The error in choosing a rubber leads to two problems: either the tire will not stand on the rim, or quickly wear out. The main parameter is the size, which is indicated in the format D×W (diameter × width).

The second criterion is material: Cheap hard rubber tires (60A) last longer, but they are less cushioned, and soft tires (50A) provide better grip, but they wear out faster. The best option for the city is 55A.

The third thing is the tread direction, and the sidewall of the tire should have a needle that says Rotation or Direction, and if you put the wheel in the opposite direction of rotation, the water and dirt will not be removed efficiently, and the wear will accelerate by 30 to 40 percent.

⚠️ Warning: The tires for Xiaomi M365 and Pro 2 are visually similar, but have different rim widths. If you put a 2.5" tire on the rim 2.125," it will "walk" when moving, which will lead to imbalance and vibration.

2.Scooter preparation: removal of the wheel and dismantling of the old tire

Before removing the wheel, completely discharge the battery - this will eliminate the risk of short circuit in case of accidental damage to the wiring.

1. Remove the wheel: 🔧 Unscrew 4 wheel mount bolts with a 10 mm key (on the Pro 2 and later - 5 bolts). 🔌 Unplug the motor-hall connector (it is usually fixed with a screed). Don't pull the wires! 🖥️ Take pictures of the cables' location so as not to confuse the reverse assembly.

Let the air down:

Dismount the tire:

• ⚙️ Insert the tire lever between the rim and the tire, then gently tuck the edge.
• 🔄 Repeat from the opposite side, gradually turning the tire outwards.
• 🚫 Don't use screwdrivers or knives - they will damage the camera or rim!

If the tire is stuck to the rim (often after long use), moisten the edge with soap solution or use silicone lubricant. Never use WD-40 or other solvents - they destroy the rubber.

⚠️ Attention: On scooters Xiaomi 1S And the newest sensor in the rear wheel. ABSWhen you remove the wheel, don't pull the sensor wires, they're fragile and they break easily. If the connector is oxidized, clean it with alcohol.

3. Installation of a new tire: step-by-step instructions

The process of installing the tire is reversed, but there are several critical points:

1. Check the camera: If it is intact, you can use the old one, but it is better to replace - the old rubber loses elasticity and punctures more often. Pump the camera to 1.5-2.0 bar and check for leaks (by immersing in water or applying soap solution).
2. Place the camera in the tyre: 🔄 Sprinkle the camera with talc or baby powder - this will prevent twisting when pumped. 📍 Insert the nipple into the rim opening, then carefully distribute the camera inside the tyre.

Put the tire on the rim:

• ⚙️ Start with the side opposite the nipple. Use the levers, but don't apply excess force.
• 🔍 Make sure the edge of the tire is evenly placed in the groove of the rim - if the side of the tyre is out somewhere, the wheel will beat.
• Pump the wheel: Pressure should be 2.5-3.5 bar (see the exact values on the sidewall of the tire). Use a pump with a pressure gauge!

Critical error: Many users forget to turn the wheel after installation, so that the camera spreads inside the tire. If not, the tire can break on the first trip.

💡

If the tire sits tight on the rim, moisten its edges with soap solution or use a special mounting paste. Don't use oils - they destroy rubber!

4. Features for tubeless wheels (Tubeless)

The Xiaomi 3, 4 Pro and some Pro 2 scooters are equipped with tubeless tires, and their replacement is more difficult:

• 🔧 A compressor will be required (a hand pump will not create the pressure required for sealing).
• 🧴 You should use a sealant for tubeless tires (for example, Slime or Hi-Gear).
• 🔄 After installation, the wheel should be "planted" on the rim by a sharp injection of air (up to 4-5 bar), then fired to the working pressure.

If the wheel continues to flow after pumping, check:

• 🔍 Rim integrity (cracks or burrs).
• 🧲 Correct installation of the tire side (it should fit evenly).
• 💧 A sufficient amount of sealant (usually 60–100 ml per wheel).

5. Wheel Balancing: Why It Matters

An unbalanced wheel causes vibrations at speeds above 20 km/h, accelerated wear of bearings and discomfort when driving.

1. Static method: 🔄 Hang the wheel on a nail or hook (for example, through a hole in the hub). 📍 Wait for it to stop. Repeat 3-4 times — if the heavy point always appears at the bottom, you need loaders.

Dynamic method:

To balance, use adhesive weights (weighing 5-20 g) that are glued to the rim. On Xiaomi scooters, usually 10-15 g on each side is enough, and the exact position is determined by experiment.

💡

Balancing is required after the tire is replaced, but it is also required every 1000-1500 km of run or after heavy impacts (for example, after falling into a pit).

6.Scooter assembly and test trip

After the tire is installed:

1. Connect the motor-hall connector (make sure the contacts are clean and not oxidized).
2. Twirl the wheel mount bolts cross-cross to avoid distortion. The moment of tightening is 25-30 Nm (do not pull!).
3. Check the brake movement – if the wheel rubs against the pads, adjust the eccentric.
4. Make a test trip at low speed (10-15 km/h) by checking: 🔊 No extraneous noise (squeaking, knocking). 🚲 Rectile motion (scooter should not be taken aside). 🛑 Braking efficiency.

If after replacing the tire scooter became worse to accelerate, check:

• 🔋 Battery charge (discharged battery limits power).
• 🔧 Correct connection of motor connectors.
• 📉 Wheel pressure (too low pressure increases resistance).

⚠️ Warning: On Xiaomi Pro 2 scooters and later, after changing the wheel, the brake calibration may reset. To restore it, press the brake lever for 5 seconds with the scooter on.

7. Frequent mistakes and how to avoid them

Analysis of the calls to service centers shows that 85% of problems after self-replacement of the tire are associated with five errors:

Another common problem is that the nipple is damaged when pumped, so to avoid this, use a flexible hose pump and don't use excessive force, and if the nipple does break, it can be replaced with a camera repair kit (costs ~200 rubles).
