I’m sorry but it’s not possible. The tires and wheels installed on the scooter cannot be replaced. Larger scooters may have tires (tires) suitable for a wider range of surfaces.
You want more speed, well then you want a bigger tire (larger overall diameter). However, you will sacrifice acceleration, which can be a bit excessive depending on the altitude. For most scooters, the tire diameter cannot get much larger because in most cases it rubs against the crankcase.
The best way to inflate a tire is to use a regular foot pump or bicycle pump (a hand pump is fine too). You will see that the valve type is a Schrader valve or a Presta valve. Once you know what you need, you can simply set up the pump accessories, assemble them and then start the pump.
The same goes for scooter bikes. Smaller wheels transmit bumps and blows to the rider much more seriously than larger ones. The larger the wheel, the more an object can tip over without being damaged. However, smaller wheels offer worse handling than larger wheels.
As the rubber hardens, cracks and loses grip over time, it is recommended that tires be replaced every five years, even if they still have a lot of tread.
Tubeless tires are common on cars where only the tire forms an airtight seal around the rim. With some electric scooters, you basically have to take the entire bike to a tire shop and remove it there with the tire changer.
