Installation of cast tires on Xiaomi electric scooters: the full guide

Owners of Xiaomi Mi Electric Scooter are often faced with punctures that can take them by surprise away from home. Standard inflatable cameras, which come as standard, are sensitive to sharp objects and temperature changes, which forces riders to look for alternative solutions, which is why the question of how to put a cast tire becomes one of the most pressing questions for the user community.

Switching to a solid tire drastically changes the performance of your device, eliminating the risk of sudden wheel descent. However, this process requires certain physical efforts, special tools and a clear understanding of the sequence of actions so as not to damage the rim or the tire itself during installation. In this guide, we will discuss in detail all the stages of replacement, necessary tools and technical nuances that will help you to get the job done efficiently and safely.

Advantages and Disadvantages of Whole Tires for Xiaomi

Before you start dismantling an old wheel, it is important to weigh the pros and cons, because cast tires have their own specific characteristics. The main advantage is absolute impenetrable: you will never again encounter nails, glass or spikes on the road, and this is especially true for those who use a scooter as their main transport for commuting to work or school, where lateness due to wheel repair is unacceptable.

However, when installing a solid tire, you have to be prepared to change the behavior of vehicles on the road. cast rubber is much harder than pneumatic, which leads to a decrease in cushioning and transfer of all vibrations from asphalt irregularities to the frame and rider. Riding comfort is reduced, and the range can be reduced by 10-15% due to increased wheel weight and greater rolling resistance, which is worth considering when planning routes.

• 🛡️ Full protection against punctures and no need to carry a pump or remix.
• ⚖️ Increased weight of the scooter, which can be critical when lifting the device up the stairs.
• 📉 Decreased coast down and dynamic performance due to lack of air shock absorbing effect.
• 🔧 Difficulty of installation requiring special tools or heating to be installed on the rim.

Despite the toughness of the ride, many users see the replacement as a justified investment in reliability, especially if the roads in your city leave much to be desired.

Tools and preparation for work required

The success of the operation to replace the tire by 80% depends on the correct preparation of the workplace and the availability of the right tools. The standard set of keys, which comes with a scooter, will be categorically insufficient, since the cast tires are high density and tightly fit on the rim, you will need to build a "mechanic kit" that includes specific tools for working with rubber and wheels.

The key is to choose the method of installation: mechanical (with levers) or thermal (with heating). Depending on the strategy chosen, the list of tools will vary slightly, but the basic set remains the same. Do not try to use random objects like screwdrivers or knives - this will damage the rim or break a new tire.

You'll need strong steel or hardened plastic mounting blades to work, which will allow you to pull the tire side without damage. A building hair dryer or boiling water tank will also be an indispensable tool if you plan to use a thermal method of expanding rubber. A fitting grip is ideal for the wheel, but you can also do with a reliable strubbine mounted on a stable table.

• 🔧 A set of wrenches (usually 8 mm, 10 mm and 12 mm) for wheel disassembly.
• 🌡️ Temperature-adjusted building dryer or large kettle with boiling water.
• 🧤 Durable working gloves to protect hands from cuts and burns.
• 🧴 Soap solution or special lubricant (talc, silicone) to facilitate slipping.

Be sure to clear the space around you beforehand, as the process can be messy and require sudden movements.If you work indoors, ensure good ventilation, especially when using chemical lubricants or heating rubber, which can emit a specific smell.

Dismantling the wheel and removing the old tire

The first step of any replacement is to remove the wheel from the scooter design. For Xiaomi Mi M365, Pro and Pro 2 models, the procedure is standard, but requires care when turning off the electrical contacts. Turn the scooter upside down, pre-switching the power to avoid short circuit in the engine circuit.

Unscrew the fasteners holding the wheel axis and carefully remove it from the fork. Be careful with the motor-wheel wires: do not pull them sharply so as not to damage the connectors or insulation. After removing the wheel, remove the old pneumatic chamber and tire if you change them in the complex.

⚠️ Before starting work, be sure to disconnect the battery or make sure the scooter is off.Neglective handling of motor-wheel wires can cause the controller to fail.

Flow the air out of the old chamber completely and, using mounting blades, squirt the side of the tire, turning it outwards. Move around, gradually releasing one side of the tire, and then the other. After removing the rubber, carefully clean the rim of any residue of dirt, glue or rust, as any grain of sand can cause the wheel to beat or damage a new cast tire during installation.

If you only change the tire, leaving the old rim, pay special attention to the condition of the spokes and mounts. The cast tire puts a higher load on the wheel design, so any backlashes or defects must be corrected before installation begins. Check the nut tightening on the bushing and make sure the bearings rotate freely and without noise.

Installation technology: heating or mechanics?

There are two main ways to install a cast tire on the rim of an electric scooter, and the choice between them depends on your physical abilities and the availability of equipment. The mechanical method requires considerable hand strength and the use of levers, while the thermal method is based on the physical property of rubber to expand under the influence of high temperature.

The thermal method is considered more gentle for the tire itself, as it minimizes the risk of rupture of the sides under excessive tension, for this purpose, the tire is immersed in boiling water for 10-15 minutes or intensively warmed with a building hairdryer on all sides, paying special attention to the internal diameter, the rubber becomes elastic and increases in size, which makes it easy to pull it on the rim.

The mechanical method involves the use of special devices, such as vise or homemade screeds, which compress the tire, reducing its diameter to put on the wheel. Often a combination of methods is used: the tire is slightly warmed up, and then use the levers for the final landing, the main thing is to act consistently and not rush to avoid injury.

• 🔥 Thermal method: heating to 80-100°C, requires caution not to melt the rubber.
• 🛠️ Mechanical method: use of rods and shoulder blades, high risk of damage to the tool or hands.
• 💧 Combined method: light heating plus lubrication with soap solution for better sliding.

Regardless of the method chosen, it is critical to correctly orient the tire on the rim. On the inside of the cast tire there is usually an arrow indicating the direction of rotation, or a marking that must be combined with a nipple hole (if provided by the design of the tire) or simply evenly distributed in the center. Misplacement of the tire "upside down" can lead to rapid tread wear and deterioration of traction.

Step-by-step instructions for installing a cast tire

Consider the installation process using a combination method that performs best at home, first locking the wheel firmly in the vise or pinching between two stable surfaces so that it doesn't twist during operation.

A heated or lubricated tire is placed on one side of the rim, starting from the area opposite the vent or the nipple. Using the mounting blade, push the inner side of the tire and throw it over the edge of the rim, moving in a circle, at which point it is important not to damage the internal structure of the tire and not to scratch the disc.

Once one side is fully seated, move to the other, which is the hardest part, the most demanding part, the most demanding part, put the edge of the tire in a fixed position (like the edge of the visceral cushion or a special stand), and push the opposite part of the wheel, turning the tire on the rim, the movements should be confident and smooth.

💡

Use baby soap or shampoo as a lubricant. They glide perfectly, and when dry, they don't leave a sticky layer, unlike oil or solidol, which can erode rubber.

Once the tire is fully worn, check its position around the perimeter again, it should fit tightly and evenly to the rim, without distortions and gaps. If you notice a skew, it is better to correct the tire immediately before it finally cools down and "grabs" with the rim.

Final assembly and performance check

After successfully installing the cast tire on both wheels (or one if changed selectively), you need to return the wheels to their place. Insert the axis of the wheel into the seat of the fork, carefully straightening the motor-wheel wires so that they do not fall under the fasteners and do not rub during the ride.

Twirl the fasteners and nuts to ensure a uniform puff. Be sure to check the nut tightening on the wheel axis itself, as vibrations from a rigid cast tire can contribute to their spontaneous unwinding in the first kilometers of the run.

⚠️ Attention! After installing the cast tires, be sure to take a test ride at low speed in a safe place. Check the brakes, as due to the lack of cushioning, the effectiveness of braking may change, and also listen to extraneous sounds.

Make a few laps around the house, checking the stability of the scooter and the absence of wheel beat. cast tires take some time to "grab" to the rim, so in the first 10-20 kilometers avoid sharp jerks, jumping from curbs and extreme driving. Let the rubber finally take shape and fix on the disk.

Regularly inspect the condition of the cast tires during operation. Despite their high wear resistance, the appearance of deep cracks or detachment from the rim signals the need for replacement. A properly installed quality tire will last you thousands of kilometers, ensuring reliability and safety of trips.
