I really wouldn't recommend it, especially the microwave part. Have you tried buying some slime? The air tires offer better ride experience (they absorb the bumps) and I've seen people say they get slower speeds with solid tires. If you really are insistent - I'd use a spare microwave that you can toss afterwards, you don't know what kind of fumes cooking a tire in the microwave can release. Better safe than sorry.
What tire pressure am I supposed to use? Just pulled the scooter out since the weather is improving and found the tires completely flat. thanks.
I assume you're talking about the Xiaomi m365? The recommended tire pressure is 50psi for both front and back IIRC.
