*START HERE* with our Sizing Guide: Your e-scooter's wheel is either "pneumatic" or "non-pneumatic." This means that you either put air in them and there is an Inner Tube and an Outer Tire; OR you do not and therefore it would be a solid rubber or solid plastic tire. "Pneumatic" tires are better because they provide the resistance and shock value and the 'riding on air' feeling. Plastic Non-pneumatic tires are close to junk, and if your e-scooter is "non-pneumatic," you will have a tough time installing new solid rubber tires because it requires a large amount of force from a specific "crank" machine that is only offered in China. If your e-scooter is pneumatic, congratulations! You made a better consumer decision, but perhaps the tire went flat on you, well now you can fix it yourself with the help of this guide. Your e-scooter outer tire (the rubber) will have numbers on it. Those numbers will either have American Values i.e. numbers in inches(") OR 2 or 3 ' aspect ratio' numbers. For instance : 8.5" x 2" or "Eight and a half Inches by Two Inches" is the same as a ' 50/75-6.1' And the tire may only say one of these things on it. Scooter Operations has thus come up with size categories and sizes for MOST if not ALL pneumatic e-scooter wheels. Maybe in the list below you can find your specific e-scooter model that we have fixed and filmed in our "Virtual Repairs Shop." OR MAYBE in the list below can find the same size tire from a comparable e-scooter model to yours as the e-scooter brand and model market is extremely saturated. From there, Go our Classroom, where you will find full-scale videos on how to dismantle your e-scooter wheel, replace the inner tube and fix your flat tire from start to finish. Each and every lesson is broken down into 2 Parts where in Part 1 we take the wheel and tire off and apart and out and identify the tube and order it and in Part 2 we "Put Humpty Dumpty back together again," or re-assembling the e-scooter so it becomes ridable.

These are the 5 "Golden" Inner Tube Sizes. I will soon have these five size tubes in inventory in stacks in my shop because these 5 sizes are the ones that fit most of the e-scooters that come through my shop (in Phoenix, Arizona.) The key point here is that these tubes can be dependent upon the angle of the "Valve Stem," on your model e-scooter --And Yes, the Angle of the Valve Stem can be specific as well... it is therefore always most useful to identify which tube to buy by replacing the inner tube exactly for what it is when you remove the old one. Because of the angle of the valve stem, various links are provided because they are sourced from various places. E-Scooter Tires, also have a "3 Value Name," --3 numbers stamped on them, which is similar to Motorcycle Tires. To me, the "3 Values" don't make intuitive sense, but I found this post that explains it if anyone wants to read on it. But for now, these are the Five Golden Sizes of E-Scooter Inner Tubes: [ "S" - 8.5" x 2" w/ Straight Valve Stem, 8.5" x 2" w/ Angled Valve Stem - 50/75-6.1 Fits: JETSON "M" - 10" x 2.125" w/ Straight Valve Stem, 10" x 2.125" w/ Angled Valve Stem -60/70-6.5, also called 10' x 2.50" or 10 x 2.125-2.50 Fits AOVO PRO ESMAX "L" - 10 x 2.75" - 3" w/ Straight Valve Stem, 10 x 2.75"-3" w Angled Valve Stem - 70/65-6.5 OR 85/65-6.5 (CUNFUN)
