How to wear a cast tire on a Xiaomi scooter: full instructions

Xiaomi’s electric scooters, especially the popular M365, Pro and Pro 2 models, are initially equipped with inflatable chamber tires. However, many riders face frequent punctures, which forces them to look for more reliable alternatives. The cast tire becomes the ideal solution for those who want to forget about the puncture of cameras and the risk of a sudden deflection of the wheel on the road.

The process of installing this type of rubber is very different from replacing a conventional camera and requires some physical training, as well as knowledge of specific techniques. Unlike an elastic inflatable tire, a solid structure made of polyurethane or rubber is highly rigid, which makes installation a time-consuming task. You will need not only a set of tools, but also patience to do the job properly and not damage the rim of the disk.

In this article, we will take a detailed look at all the stages of preparation and direct installation, paying special attention to safety and the nuances of working with rigid materials. The right approach will allow you to avoid common mistakes that can lead to rim deformation or improper fitting of the wheel. Prepare for the procedure to require physical effort, but the result in the form of “hazardless” driving is worth it.

Tools and workplace preparation required

Before you start dismantling the old wheel and installing a new one, you need to organize a comfortable workspace. You need a sturdy table or workbench that will not stagger under pressure, because the process requires considerable effort. Lack of proper preparation can lead to injuries or damage to the components of the scooter.

The basic toolkit should include specialized gears for working with wheels. Without them, trying to pull a rigid tire may be unsuccessful or take a disproportionately long time. It is recommended to check in advance for all positions so as not to interrupt at the most critical moment.

• 🛠️ Set of hexagons and screwdrivers for removing the deck and dismantling the wheel.
• 🔥 Building hair dryer or hot water source to soften the tire material.
• 🧴 Soap solution or special lubricant (talc, silicone) to facilitate slipping.
• 🔨 Wooden or plastic blade (mounting) for tweaking the edges of the tire.

Special attention should be paid to the choice of lubricant. The use of aggressive chemicals such as gasoline or solvents can destroy the structure of polyurethane or damage the paint on the disk. Soap solution is the safest and most effective option, providing a good sliding without harm to materials. Once drying, it does not leave sticky traces, unlike some oils.

Dismantling the wheel and removing old rubber

The first step is to remove the wheel from the scooter. For Xiaomi M365 and Pro models, this usually involves unscrewing several bolts that attach the motor wheel or front fork to the frame. Before starting work, be sure to turn off the power of the scooter and, if possible, disconnect the motor connector to avoid short circuit.

Once the wheel is removed, the old tire must be removed. If you change the camera to a cast tire, the old rubber and camera must be completely removed. Often, it is difficult to remove the rubber that is stuck, especially if there is a sealant inside. Carefully clean the rim of the disk from the glue, dirt and rust, as any irregularity will prevent the new cast tire from fitting tightly.

⚠️ Warning: When working with a construction dryer, be careful with the plastic disc elements and electrical wires inside the motor wheel. 60-70 degrees so as not to damage the insulation of the winding or magnets.

If there are traces of old rubber on the disc, they can be gently scraped off with a plastic spatula. Use metal tools with extreme caution so as not to scratch the surface of the rim, which in the future may make it difficult to install a new tire or cause it to wear unevenly.

Methods of softening the cast tire before installation

The key to the whole procedure is pre-conditioning the cast tire itself. The material they are made of is very hard at room temperature, making it almost impossible to pull it on the disc manually. There are several proven ways to make the rubber more elastic.

The most common and affordable method is to heat the tire with a construction hair dryer. Warm the inner surface of the tire evenly around the perimeter, constantly rotating it. Don't hold the flow of hot air at one point for too long so as not to melt the material. The goal is to warm the rubber to a state where it becomes soft and malleable, but does not begin to deform or melt.

An alternative, safer way for beginners is to soak the tire in boiling water, which would require a bucket or pelvis where a steep boiling water is poured, and the tire is immersed for 15-20 minutes, which ensures uniform heating throughout the thickness of the material, reducing the risk of local overheating that is possible when working with a hair dryer.

Some craftsmen recommend a combination approach: first heat the tire with a hair dryer for a quick start, and then as you install it, pour hot water or continue local heating in places of greatest resistance, the main thing is to take your time and let the material become really flexible before trying to pull it on the disk.

Technology of installation of cast tire on disk

Once the tire is heated and elastic, we'll move on to the most critical step: lubricate the inner surface of the tire and rim with soapy solution, which is critical to reduce friction, set the disc vertically or lock it in a vise (through a soft pad) so that it doesn't turn.

Start putting the tire on one side, gradually pulling it on the rim. Use a mounting blade or a screwdriver with a wide sting (wrapped in a cloth so as not to damage the rubber) to pull the edges. The movements should be progressive: stretched the site, checked the landing, moved to the next. Don't try to pull the entire tire on one side at once, this will lead to a skew.

You may find yourself in a situation where the tire stops pulling, and this is a signal that the material has cooled and become stiff again, so you have to stop working and reheat the problem area with a hairdryer or lower the wheel into hot water, and continuing to push the tire cold can cause the tire to break or the tool to break.

When the tire is fully stretched on the disc, check the uniformity of the landing along the perimeter. It should sit tightly, without distortions or gaps. If one side is stretched stronger than the other, carefully move the rubber until it stands symmetrically relative to the center of the disk.

Comparison of installation methods and their effectiveness

There are several approaches to installation, and each rider chooses the best one for himself. Understanding the pros and cons of each method will help avoid disappointment. Below is a table comparing the main ways to install cast tires.

Using a specialized machine to side the wheels greatly simplifies the process, but requires the availability of equipment that not every homemaker has. Freezing the tire before installation (place in the freezer for a couple of hours) makes the material more fragile, but when heated sharply, it can behave unpredictable, so this method requires caution.

⚠️ Warning: Never use an open flame (a gas burner without a nozzle) to heat polyurethane tires. Open fire instantly melts the material and releases toxic substances, making the tire unusable.

The most balanced option for home conditions is the combination of heating and abundant lubrication, which allows you to control the process and minimize the risks. Remember that the quality of the installation directly affects the safety of the ride and the life of the wheel.

Final assembly and performance check

Once the tire is successfully installed, let the wheel cool to room temperature, so that the material will "grab" and take its final shape, and check if the tire on the disc turns when it cools down, sometimes when the hot material shrinks, the landing may weaken.

Set the wheel back on the scooter. Connect the motor connector (if you change the rear wheel), keeping polarity and fixing the connector until you click. Twist all the fasteners with the necessary force, using a dynamometer key or focusing on the standard tightening for your Xiaomi model.

The first run-in should be in a gentle mode. Avoid sudden starts, braking and driving through irregularities in the first 10-15 kilometers. This will allow the tire to finally "wear" to the disk. During operation, periodically check the condition of the tire for displacement or cracks.

💡

To extend the life of the cast tire, avoid driving on wet asphalt and puddles in the cold season - polyurethane loses traction and becomes tougher in the cold.

Now your scooter is equipped with a reliable puncture protection, cast tire will provide stability and no need to carry a pump or remix, but it is worth remembering that the stiffness can increase slightly compared to an inflatable camera.
