What Makes a Split Rim Useful?

A split rim is designed to separate into two rim halves. Instead of forcing the tire over a solid rim with tire levers, the rider can release the air, remove the rim screws, and separate the rim from the tire more directly. This helps reduce the force needed during a tire change and lowers the risk of damaging the tire bead or scratching the rim.

On the Hiley Tiger EVO GTR, the split rim design is especially useful because the scooter also includes a quick disconnect for the motor cable. This allows the full rear wheel assembly to be removed from the scooter before the tire is changed. With the wheel off the scooter, the user has more room to work, clean, inspect, and reinstall parts carefully.

Tools Needed for the Tire Change

Before starting the tire change, it is important to prepare the correct tools. For the axle nuts, a 21 mm socket is needed. A torque wrench is recommended, especially because the axle nuts should be tightened to around 40 Nm during reinstallation.

• 21 mm socket or adjustable wrench for the axle nuts
• Torque wrench that supports around 40 to 45 Nm
• 3 mm, 4 mm, and 5 mm Allen keys
• Wire cutters for removing zip ties
• Pliers for removing tight locking washers
• Microfiber cloth or paper towels for cleaning
• Cleaning solution for the rim and motor area
• Clamp for helping align a tighter tire
• Floor pump with Schrader valve support

A floor pump is helpful because it can push air into the tire quickly. This makes it easier to seat the bead after the rim and tire are reassembled.

Step 1: Remove the Rear Fender

The rear fender should be removed first to create more room around the wheel. On the Hiley Tiger EVO GTR, the rear fender is not wired into the tail light, so there is no tail light cable to unplug. The fender is held by four screws, which can be removed with a 3 mm Allen key.

After the fender is removed, it is a good time to wipe away dust and debris around the rear wheel area. Keeping the workspace clean helps prevent dirt from entering the rim sealing surface later.

Step 2: Remove the Axle Nuts and Disconnect the Motor Cable

The next step is to remove the axle nuts from both sides of the rear wheel. If the nuts are very difficult to loosen, heat can be applied with a heat gun or hair dryer. This helps soften the thread locker and makes the nuts easier to remove.

Once the axle nuts are removed, the locking washers on both sides of the wheel should be taken off and set aside. These washers must be reinstalled in the correct position later.

The Hiley Tiger EVO GTR includes a quick disconnect motor cable. After loosening the connector, the motor cable can be separated from the scooter. The zip tie holding the cable should also be cut. At this point, the wheel assembly can slide out of the rear frame.

Since the rear motor is heavy, removing it changes the weight balance of the scooter. The scooter should be supported securely during the process.

Step 3: Remove the Brake Rotor and Release the Air

After the wheel assembly is removed, the brake rotor can be taken off. Before removing it, it is helpful to mark its orientation with tape. This makes it easier to reinstall the rotor in the same direction later.

The brake rotor is held by six screws and can be removed with a 4 mm Allen key. After the rotor is removed, all air should be released from the tire by pressing the valve core. The tire must be fully deflated before opening the split rim.

Step 4: Open the Split Rim Correctly

The Hiley Tiger EVO GTR rear wheel has 12 outer rim screws. These are the screws that need to be removed to split the rim. The inner screws hold the motor assembly together and should be left untouched.

After the outer rim screws are removed, the rim can be separated from the motor assembly. Then the tire sidewalls can be squeezed to loosen the bead. Once the bead is loose, the two rim halves can be removed from the tire.

This is where the split rim design shows its practical value. The tire can be removed without fighting the bead over a fixed rim. The process is cleaner, more direct, and easier for riders who want to handle basic maintenance themselves.

Step 5: Clean the Rim Before Installing the New Tire

When the rim is open, areas that are usually hard to reach are fully exposed. This is a good opportunity to clean the inside of the rim and motor area.

The sealing surface should be free of dirt, dust, and debris. One side of the rim includes a rubber gasket, and that gasket should remain in place. It should not be pulled out or disturbed during cleaning.

A clean sealing surface helps the tire seat properly and helps maintain reliable air pressure after reassembly.

Step 6: Check Tire Direction Before Reassembly

Before installing the new tire, the rotation direction must be checked. Many scooter tires include a rotation arrow on the sidewall. This arrow shows the correct rolling direction of the tread.

The new tire should be installed so the tread direction matches the scooter’s forward movement. On the Hiley Tiger EVO GTR, this is especially important when reinstalling the motor and brake rotor in the correct orientation.

In the documented tire change, the new CST tire had a tighter fit than the original tire. A clamp was useful for holding one side of the rim down while the other side was aligned and secured.

Step 7: Reinstall the Rim and Motor Assembly

During reassembly, the rim halves should be aligned carefully with the tire and valve stem. The screws should be started by hand first. Instead of fully tightening one screw at a time, it is better to tighten them gradually in an alternating pattern.

This helps keep the rim halves evenly aligned and reduces uneven pressure on the tire bead. After the rim halves are secured, the motor can be placed back into the wheel assembly and the remaining screws can be tightened.

Step 8: Inflate the Tire and Seat the Bead

Once the rim and tire are reassembled, the tire should be inflated. A floor pump can be more effective than a small electric pump because it moves air into the tire quickly. This can help the bead snap into place against the rim.

After inflation, the tire should be inspected to make sure the bead is seated evenly. The tire direction should also be checked one more time before the wheel is installed back onto the scooter.

Step 9: Reinstall the Wheel Assembly

The locking washers should be placed back into position, and the brake rotor should be reinstalled in its original orientation. Then the wheel assembly can be placed back into the scooter frame.

The axle nuts should be tightened to around 40 Nm. After that, the motor cable should be reconnected. The connector fits in only one direction, so it should be aligned carefully before tightening.

A new zip tie should be used to secure the motor cable. Before reinstalling the rear fender, the wheel should be tested while lifted to confirm that it spins smoothly and does not show obvious wobble.

Why This Design Matters for Long Term Maintenance

Tires are wear parts. Over time, riders may need to replace tires because of mileage, tread wear, punctures, or riding style changes. A scooter that makes tire replacement easier can reduce maintenance stress and make long term ownership more practical.

The Hiley Tiger EVO GTR combines two helpful service features: a split rim and a quick disconnect motor cable. Together, these details allow the rider to remove the full wheel assembly, open the rim, clean the sealing area, install a new tire, and reassemble the wheel with a clearer process.

For riders who care about daily use, service access, and lower maintenance difficulty, the split rim design is a meaningful advantage. It makes tire changes less intimidating and gives users more control over basic scooter care.

Final Thoughts

The Hiley Tiger EVO GTR shows how small design details can make electric scooter ownership easier. Its split rim structure reduces the need for tire levers, while the quick disconnect motor cable allows the rear wheel assembly to be fully removed from the scooter.

With the right tools and careful attention to screw positions, tire direction, washer placement, and axle torque, the tire change process becomes much more manageable. For riders who want an electric scooter that is easier to maintain over time, the Hiley Tiger EVO GTR offers a clear advantage in real world serviceability.
