  • Great price, quality tubes!
Size: 8.5x2" (TR4A) Style: Extra Thick Tube
I got the exactly replacement tubes I needed for my Razor scooter rear tires that were constantly going flat. These are a lot thicker material than the original tubes, which Is a good thing for longevity and strength. They also came with the tire tools that really help get the tire on and off the rim. These were a good price, shipped and fast. I absolutely recommend this seller amd product. ... show more

This tire/tube combination works good. The air fill valve is hard to get most air fittings connected.

  • Wrong valve for the razor dune buggy
Size: 8x2"/200x50 (TR87) Style: Regular Tube
The razor dune buggy has valves with a right angle. This is needed to reach past the plastic wheel so you can connect a pump to fill it with air. The valves on these tubes do not have a right angle. It is way more- about 75 degrees. When I installed this new tube the valve doesn’t stick out enough to connect a pump. A work around is to use a slim needle nose pliers. You have to hold the valve with the pliers away from the rim so you can connect a pump. A pain but it works. I didn’t want to go through returning this and waiting for the correct tubes so I kept them. These tubes are not for the razor dune buggy even though it claims to be. ... show more
