• 12-1/2x2-3/4(12.5x2.75) knobby tire and inner tube, for Razor Dirt Bike Rocket MX350 MX400
  • Fits for many mobility scooters, mini bike, pocket bike, Chinese electric scooters, gas scooters and other applications with same tire size
  • Brand new isobutylene isoprene rubber tire, NOT recap, this inner tube is made of isobutylene isoprene rubber, which is better in air tightness, elastic damping and aging resistance than natural rubber
  • Inflatable inner tube with TR13 straight stem and a cap
  • High puncture resistance, durability to tearing and chunking

Worked great, easy to install, It installs faster than removing the old tire. and it is cost effective.

It's perfect for my little brothers motor bike, which tire popped, haven't had any issues!

I took a gamble on these hoping they'd fit my daughter's Oset 12.5 eco. They work great! Rubbed a little on the front mud guard until I adjusted it up all the way. The previous owner had put road tires on it when his kids wore the old tires out. I put a set of these on and my kid no longer slips around when she hits a muddy patch in the yard. They look a lot better on it too.

Bought this to replace the original tires and delivered on time and fit perfectly on rims.

Great price for a heavy duty tube for my daughters oset dirtbike

Great quality at a great price.

This tire and tube is very sturdy. Fit the Razor very well. We will get a lot of miles out of this. Just have to stay away from nails and sharp stickers:) Would recommend.

This tube has worked great so far. The back tire got punctured by a nail and went flat. The biggest challenge was getting the back wheel off the bike. I have not had any problems with the tire since I replaced the tube with this one.
