Features

  • PERFECT XIAOMI M365 COMPATIBLE INNER TUBE REPLACEMENT - Xiaomi's M365 electric scooter model has front and rear tires that are 8.5 inches in diameter and are 2 inches thick. These 2-pack scooter replacement inner tubes have the exact dimensions to fit Xiaomi M365 tires.
  • COMPATIBLE WITH A WIDE VARIETY OF SCOOTERS - This type and size of inner tubes are popular among electric and gas scooters, pocket bikes, mini choppers, mini bikes, and mobility scooters. Several brands that have models compatible with these replacement inner tubes include Razor, Bladez, Gotrax, and more!
  • EXTRA THICK BUTYL RUBBER INNER TUBES - With thick, shock-absorbent butyl rubber, you feel the bumps and potholes as your scooter glides along. These replacement inner tubes are .5 mm thicker than average inner tubes providing a higher impact dampening effect. Aside from that, these tubes are also chemical, weather, tear, and wear-resistant.
  • SAFETY FIRST IS OUR MOTTO: Heavy-duty inner tube and tire. When and if punctured, it immediately creates an airtight seal to prevent damage, destruction and injury to the rider. Safe in any season or weather condition.
  • IMPORTANT NOTE: This replacement kit is an aftermarket product produced by CalPalmy (TM). It meets or exceeds the performance of OEM replacements (based on in-house testing). We do not have any affiliation with or endorsement from any of the manufacturers mentioned.

  • Works as described- read the review - need the tools
Size: 8.5x2" (TR4A) Style: Regular Tube
Product is good. Getting them on the rims is another story (not their fault). Watch some videos before you walk this path and know what you’re up against. I managed to get 3 out of 4 done! Buy tire spoons, don’t use the screw driver , and boil the external tire (yes boil it) to make it soft enough to manipulate. Watch more than one video and find one that actually shows the mounting (not just before & after) ... show more

  • Quick and fixed my scooter
Size: 8.5x2" (TR4A) Style: Regular Tube
The inner tube's came quickly, fit and got my grandson back riding his scooter to work. You need two people to put in inner tubes.

  • FINALLY delete me..wong product
Size: 8.5x2" (TR4A) Style: Regular Tube
DELETE ME...WRONG PRODUCTheses will fit the GoTrax GXL v2 but you'll need beer and some friends. 3 different people tried to get these on. Finally, one very big guy, with a mission, actually did it. We boiled the tire for at least 30 minutes, used 3 large flathead screwdrivers/prybars and 2 people to get the miserable thing on. It was awful and I would have paid at least twice for the scooter with these tires already on. The person I bought the scooter and tires for better ride it or I'm going to punch them in the throat. ... show more

  • Not for me
Size: 8.5x2" (TR4A) Style: Regular Tube
It was incredibly difficult to change the tube on my scooter's wheel, and it's entirely possible that I damaged the tube while getting it over the rim with tire. But once I changed the tube, neither one held air. However. I bought a different set of scooter tubes and both held air lasted until a nail (in one case) and a staple (in the other) punctured them. ... show more

  • Good
Size: 8.5x2" (TR4A) Style: Regular Tube
I got it just fine . It’s the fact the delivery driver was to busy on his phone that he delivered it late . If he wasn’t on his phone maybe he would’ve noticed that this order had two parts to it . People need to focus on their job more than a phone call that isn’t obviously important

  • Works as advertised but Dads, leave it the pros.
Size: 8.5x2" (TR4A) Style: Regular Tube
This is the 2nd time ordering it. The 1st tube went well, 2nd...not so much. Since I didn't have the right tools to change the tube, I punctured the 2nd tube. Got the 2nd shipment of tubes, went to a bike shop so they can handle it...screw that, I'm not waiting 3 days, dude... I took the scooter wheel and tube to a regular car tire shop and they handled it. Gave the dude a $20 b/c it looks like he broke a sweat doing changing the tubes. Anyhoo, tube works fine, Dads..save yourself the aggravation and take it somewhere to avoid the embarrassment. Thx. ... show more
