Just joined the club & Ninebot parts?

Hello, I rented scooters from our local ride share program but they're very clunky and weak so I decided to order myself a Ninebot MAX G2 after looking at some reviews. It seems like it's a very new product but I'm curious about the availability of spare parts like tires which I expect will wear out even if they're "self-healing".

Does anyone have experience with getting spare parts either first party or third party for these or other Ninebot scooters? Are the front and rear tires typically the same?

Thanks!
