A bicycle freak of mine said that it might be better to go for tyre repair gel instead, as you don’t have the effect on rolling resistence. It’s like this spray that automatically fills the hole.

I remember cycling in Barcelona on one of those e bikes. I know I looked like a total tourist and I loved it. And the shop actually told me to drive only on the sidewalks. I actually tried it but it’s impossible!
