If your E-scooter comes with innertubes that is ok! Split rims would leak air if the tires mounted to them do not have an inner tube installed in them to hold the air. We have many tips and tricks to center your tire on the rim as up until recently the E-Scooter wheels don’t have great machining tolerances from the wheel to tire bead. What is the tire bead: This is the part of the tire that mates to the wheel. It is typically steel wire covered heavily in rubber. The bead has a snug fit to the wheel to prevent the wheel from slipping rotationally in the tire. -If you have any questions on what tire fits your E-scooter please just send us an email. We will add to each tire description known fitment guides as we confirm with all the E-Scooters we see. Its best to run the same OE size or same aspect ratio tire that your scooter came from the factory. Most E-Scooters can run a + size with out issue, best to change your tire size (to the exact) in your “P setting” with in your E-Scooter. Tires calculate the aspect ratio by dividing a tire's height off the rim by its width. If a tire has an aspect ratio of 55, it means the tire's height is 55% of its width. *PLEASE SEE EACH TIRE FOR FURTHER INFO*
