My tubes kept going flat on my push golf cart because of age. The inner tubes I purchased were a perfect fit and helps my cart roll much easier.

We used these to replace the inner tube in our daughter's wheelchair stroller. It was an easy swap and works perfectly now.

Need to replace a rear inner tube of our daughters scooter. These were the perfect size. Watched a video on how to remove the rear wheel which made it easier. The tires have a strong bead which makes removing the bad inner tube but once you get it out its pretty straight forward if you've ever changed a bicycle tire. Have only used one and hopefully it was last a while but have the back up just in case.

Hey guys. You need to buy these tires. The original tires had the valve stems that pointed straight out and the reason why the original tires popped was because I was trying to air them up. The tires are thicker than the originals. They fit perfectly. Just remember to get the tire bead to seat correctly before completely airing them up. Changing the tire was a chore but that is not this products fault. Hint. After getting the tube changed out and the tire back on right. Pump the new tube up just a little to get volume in there. Then seat the tire on the rim the right way making sure the the bead of the tire is on all the way. And at this point make sure that the valve is pointed straight up. THEN fill the tire the rest of the way up with air.

I bought these for my valco baby double stroller and they fit perfectly and were much cheaper than others that were advertised for valco baby. They have held up well the few times I have used it.

Fast service. Used to replace both inner tubes in a Cars bicycle with training wheels. One old tube didn't hold air, so decided to just replace both. At that price, what did I have to lose? Really liked the angled valve stem, what a breeze to add air or check tire pressure. Now if I could only find similar ones for my hand truck, life would be a breeze!

Holds the pressure and fits the wheel on a stroller - no issues.

My wife just got a new Pride Passport Power Wheelchair and got a flat tire (staple in tire ) These tube are better than the original ones and now I have a spare tube if needed -Great price and fast delivery

Bought these to replace the flat tubes in my golf push cart. Since the wheels are small, it is hard to get the nozzle on to inflate them so these helped greatly for that. Shipped fast. I used them to replace a 12.5x 2.25 tube. I filled them with Slime so I'll probably never have to buy new ones but if I did I'd order these again.

Bought for our urbini jogging stroller. Worked perfect. Love the angled stem, makes airing up a breeze instead of a fight. We only needed one, but for their amazing price we decided we’d order through them & have a spare.
