12.5x2.75 Replacement Knobby Tire and Inner Tube, 12 1/2 x 2.75 Dirt Bike Tire Tube for Razor MX350 MX400 Dirt Rocket, X-Treme X-560, Compatible with 12 1/2x2 3/4 Electric Scooters Tire Tube(2Sets)

Boys Electric bike rear tire blew out and needs a replacement. Bike was a jetsen electric dirt bike and these worked well. So far has been a couple of days on it and still good.

Great little set of tires, size was spot on, and worked as expected.

Grreat tire n tube for real!! Easy to instal also..

These tires are a direct replacement for my sons Razor Motorcycle Mx350. Unfortunately we let the Moto sit for too long and the rear developed a flat spot and is now out of round. This is my second time replacing the rear tire. The front is easy. The rear is significantly more challenging. If you have not done it just be prepared and follow the DIY YouTube videos.

The traction for the Best Choice 12v car is mediocre. I wanted to be able to have the kids rid without the loud noise of riding on pavement with plastic. I cut off the everything but the tread to remove the metal ring embeded in the inner lip that is supposed to be used on Bike rims to allow for better stretch. A heat gun and a long flat screwdriver I was able to get these around the rims nice and tight.. Works great and reduces the noise af drive on hard ground plus give better traction on grass. Not its intended use but it works.

Only did the front so far.Valve stem is 90° so much better than a straight one on these little wheels. No issues, good value replacement.

One of the inner tubes had a pinhole and won't hold air.

One of the I ner tubes I got already had a hole in it.

I have a kid dirt bike and this tire was a perfect match for it. With tube tires, I can do them myself, or even anyone can I think. But quality of the tires seem well made but it sure smells worse than a tire shop but that doesn't matter.
