Xiaomi M365 Solid Tyres: Risks & Safer Fitting Guide

Last updated: August 2026

For a Xiaomi M365 or another scooter supplied with pneumatic tyres, the safest option is normally to keep the manufacturer-specified tyre type or use an approved equivalent. Aftermarket solid tyres are much stiffer than air-filled tyres and remove much of the cushioning that protects the rider and scooter from bumps.

A solid-tyre conversion does not automatically damage a scooter. However, the firmer ride can transmit more shock and vibration into the wheel bearings, axle, motor cable, folding mechanism, fasteners, wiring and battery mounting points. Over time, this may contribute to wear or looseness, particularly on rough ground or on a scooter without suspension. Handling, braking feel, grip, noise, comfort and range may also change.

Our recommendation: repair or replace the original pneumatic tyre first. If you still choose a solid tyre, confirm that the exact tyre is suitable for your exact scooter and wheel, and have it fitted by a competent electric-scooter technician using the correct tyre press or mounting jig.

Should you fit a solid tyre to a Xiaomi M365?

The original Xiaomi M365 design uses pneumatic tyres. These provide part of the scooter's shock absorption, so changing to a generic solid tyre is not a like-for-like repair. Some newer scooters are supplied with manufacturer-engineered flat-free or hollow tyres, but these systems are designed and tested for the models they are fitted to. They should not be treated as proof that any aftermarket solid tyre is suitable for an M365 wheel.

Possible advantages

There is no inner tube to puncture or lose air pressure.
There is no need to inflate the tyre.
A correctly matched tyre can be useful where punctures are frequent, and ride comfort is a lower priority.

Important disadvantages

The ride is usually firmer and less comfortable.
More vibration can reach the scooter's fasteners, bearings, folding parts, wiring and battery supports.
Grip and braking behaviour can change, especially on wet, loose or uneven surfaces.
Rolling resistance and tyre weight can change, so range and acceleration may be affected.
Incorrect fitment can damage the rim, motor cable, brake disc or wheel bearings.
An unapproved modification may affect warranty support for related damage. Check the manufacturer's current terms before proceeding; this does not remove your statutory consumer rights.

Safer ways to reduce punctures

Before converting to a solid tyre, identify why the pneumatic tyre keeps failing. Repeated punctures are often caused by low pressure, a worn tyre, an incorrectly fitted tube, debris left inside the casing, rim damage, a damaged valve, or the wrong tyre-and-tube combination.

Maintain the specified pressure. Check the tyre when cold and follow the pressure stated in the manual or on the approved tyre. Under-inflation can cause pinch punctures and can make the tyre move on the rim.
Replace worn parts together. If the casing is cracked, thin or damaged, fitting only a new inner tube may lead to another puncture.
Use a correctly sized, good-quality tube and tyre. The size printed in a product title is not enough; construction, bead shape and wheel compatibility also matter.
Consider an approved puncture-resistant option. A compatible reinforced tube, tyre liner or tube sealant may help, but only use a product approved for the tyre, tube and valve in question.
Use a professional fitting service. Correct installation is often more effective than repeatedly replacing damaged tubes at home.

Do not boil or microwave a solid scooter tyre

Do not use a microwave, domestic oven, boiling water, heat gun, naked flame, or any other uncontrolled heat source to soften a solid tyre. These are not controlled tyre-fitting methods. They can create fire, burn or scald risks, may damage or deform the tyre, and can expose nearby wheel, motor, cable, bearing or brake components to heat or water.

Do not assume a tyre is suitable for heating just because an online video or a generic guide recommends it. Follow the written fitting instructions supplied by the tyre manufacturer. If no approved method is supplied, use a competent technician with the correct mechanical fitting equipment.

Before fitting a solid tyre

Do not begin until every item below has been confirmed:

Exact scooter model and generation: M365, M365 Pro, 1S, Essential, Pro 2, and later Xiaomi models do not all use identical wheel assemblies.
Correct wheel: confirm whether the tyre is intended for the front or rear motor wheel.
Exact compatibility: verify rim diameter, rim width, bead shape, tyre width, outside diameter, directional markings and clearance around the fork, mudguard and brake.
Written fitting instructions: obtain instructions from the tyre supplier or manufacturer for that exact tyre.
Correct torque data: use the official service information for your exact scooter. Do not copy a generic axle-nut torque from another model.
Matching tyre systems: do not mix pneumatic and solid tyres between the front and rear wheels unless the scooter and tyre manufacturers expressly approve that combination.
Condition of the scooter: do not convert a scooter with a cracked rim, damaged axle, rough or loose bearing, damaged motor cable, bent brake disc, loose folding mechanism or signs of impact or water damage.

If the seller cannot confirm compatibility, do not fit the tyre.

Tools for a safer installation

Solid tyres can require considerable controlled force. The safest setup normally includes:

a stable workbench and secure scooter support;
the model-specific manual or service information;
correct sockets, hex or Torx bits for the exact fasteners;
a calibrated torque wrench covering the required torque range;
a purpose-designed solid-tyre press or mounting jig rated for the wheel size;
rim protectors and tyre tools approved by the tyre supplier;
a water-based, rubber-compatible tyre mounting lubricant approved for the tyre;
eye protection and close-fitting work gloves; and
small trays or labelled containers to preserve the order of washers, spacers and covers.

Do not use a screwdriver, knife or razor blade as a tyre lever. Do not apply oil, grease, penetrating spray or an unidentified lubricant. These can damage rubber, allow the tyre to move on the rim or contaminate the tread or brake.

Safer solid-tyre fitting guide

This is a general safety sequence, not a replacement for the instructions for your exact scooter and tyre. If the manufacturer's procedure differs, follow it or stop and use a professional repairer.

1. Switch off and support the scooter

Switch the scooter off, disconnect the charger and allow the scooter to cool.
Remember that the battery can remain electrically live when the display is off. Do not open the deck, battery pack or controller compartment, and do not disturb high-current wiring.
Work in a clean, dry and well-lit area away from children and pets.
Support the scooter securely so it cannot roll, tip or fall. Protect the display, brake lever and controls.
Photograph both sides of the wheel, the cable route and the order of all covers, washers and spacers before removing anything.

2. Remove the wheel using model-specific instructions

Remove only the covers and fasteners identified in the correct service procedure.
Support the wheel before releasing the axle fasteners.
On the front motor wheel, never let the wheel hang from the motor cable. Do not pull, twist, sharply bend or trap the cable.
On the rear wheel, protect the brake disc from bending, impact, oil and tyre lubricant.
Keep every washer and spacer in its original position and orientation.

Stop if a cover or fastener will not release normally, the cable route is unclear, or removing the wheel would require an undocumented electrical disconnection.

3. Remove the pneumatic tyre and inspect the wheel

Release all air from the inner tube before moving the tyre bead.
Use purpose-designed tyre tools and rim protection. Keep hands clear of pinch points.
Do not cut the tyre while it is on the wheel. A slipped blade can damage the rim, motor cable, hands or other components.
Clean the bead seat and inspect the entire rim for cracks, sharp edges, corrosion or distortion.
Turn the bearing by hand and check for roughness, noise or play. If anything is abnormal, stop and arrange an inspection.

4. Fit the solid tyre at room temperature with the correct press

Check the tyre's direction of rotation and any alignment marks before mounting.
Apply only a thin, even layer of the tyre manufacturer's approved water-based mounting lubricant to the specified contact area. Keep it away from the brake disc and pads.
Place the wheel and tyre squarely in the purpose-designed press or jig.
Seat the tyre gradually and evenly, moving around the rim in small stages. Keep fingers, cables and tools away from pinch points.
If the tyre, rim or tool begins to twist, slip or deform, release the load and stop. Excessive force usually indicates the wrong tyre, poor alignment or unsuitable equipment.
Inspect the tyre around the full circumference. It must sit centrally and evenly, with no raised sections, trapped material, twist, or gaps.

Do not fill honeycomb openings or other tyre features with silicone. These features may be part of the tyre's designed flexibility and drainage. Never drill, cut or reshape the tyre or rim to make an incompatible part fit.

5. Refit the wheel correctly

Return every washer, spacer and anti-rotation part to its original position and orientation.
Route the motor cable exactly as before, with suitable slack and no pinching, rubbing or sharp bends.
Align the wheel and brake components. Make sure the brake disc remains clean and straight.
Use thread-locking compound only if the manufacturer's procedure specifies the correct product and location.
Tighten axle fasteners and other safety-critical fixings to the official torque specified for the exact model.
Refit all covers and cable protection. Replace damaged or single-use hardware where required.

6. Complete safety checks before riding

Spin the wheel by hand. It should rotate evenly without wobble, rubbing, binding or unusual noise.
Check tyre clearance at the fork, frame, mudguard and brake throughout a full rotation.
Check that the motor cable and brake cable do not touch the tyre or get pulled by steering or wheel movement.
Operate the brake while walking the scooter. The brake must engage normally and release without binding.
Check the steering, folding mechanism, axle fasteners and all disturbed covers before switching on.
Carry out the first powered test at walking pace in a controlled private area, wearing suitable protective equipment. Do not use a privately owned e-scooter on UK public roads, pavements, cycle lanes or other public places.
Stop immediately if you notice wobble, rubbing, poor braking, unusual vibration, noise, heat, smell, loss of power or a warning code.

Checks after the conversion

A solid tyre still needs inspection. Recheck the wheel, axle fasteners, motor cable, brake alignment and tyre seating after the first short test and at regular intervals thereafter. Inspect more frequently if the scooter is used on rough ground.

Stop using the scooter and arrange professional inspection if:

the tyre moves, twists or lifts away from the rim;
the wheel develops play, roughness or a new noise;
fasteners repeatedly loosen;
the motor cable shows rubbing, stretching or damage;
the brake disc rubs, bends or becomes contaminated;
the scooter develops significantly stronger vibration or unstable handling; or
the battery area becomes unusually hot, swollen, noisy or gives off an unusual smell.

Frequently asked questions

Can a solid tyre damage a Xiaomi M365 battery or bearings?

Damage is not inevitable, and it should not be described as guaranteed. However, a solid tyre generally provides less cushioning than the specified pneumatic tyre. The resulting increase in vibration may contribute to wear, looseness or strain in bearings, fasteners, wiring, battery mounting points and other components over time. Road surface, tyre design, rider weight, speed, installation quality and scooter condition all affect the risk.

Can I soften a solid scooter tyre in boiling water or a microwave?

No. Do not use boiling water, a microwave, a domestic oven, a heat gun, a naked flame, or any other uncontrolled heat source. Use only the written method approved by the tyre manufacturer. If no approved instructions are supplied, have the tyre fitted with the correct mechanical press by a competent technician.

Is an 8.5-inch solid tyre suitable for every Xiaomi scooter?

No. A nominal size such as 8.5 inches does not confirm rim, bead, width, clearance, load or wheel compatibility. Xiaomi models and production generations can use different parts. Confirm the exact scooter model and the wheel and tyre manufacturer's fitment information before purchase.

Will a solid tyre reduce range?

It can, but the result is not identical for every tyre. The range can change because solid tyres may have different weights, diameters, rolling resistance, and deformation characteristics. Tyre fitment, rider weight, temperature, speed and surface also affect range.

Are honeycomb tyres safer than fully solid tyres?

A honeycomb design may offer greater compliance than a solid block of rubber, but quality and performance vary. It is still an aftermarket conversion unless the scooter manufacturer approves it for the exact model. Compatibility and correct fitting remain essential.

When should I use a professional repairer?

Use a professional if you do not have the exact instructions, torque data, stable support and correct tyre press; if the motor cable or brake must be disturbed; or if the tyre requires excessive force. Professional fitting is also the right choice when there is damage to the rim, bearing, axle, brake, cable, folding mechanism, or battery.

Final recommendation

For most Xiaomi M365 owners, retaining a correctly fitted and correctly inflated pneumatic tyre is the safer choice for ride quality and compatibility. A solid tyre may prevent air-loss punctures, but it introduces meaningful trade-offs and should be treated as a model-specific modification rather than a routine upgrade.

If you decide to proceed, buy a verified compatible tyre, avoid household heating methods, use the correct fitting equipment, follow the manufacturer's instructions and complete every post-installation check before riding. If in doubt, book a professional tyre fitting rather than forcing the tyre onto the wheel.
