Good tubes!
The tube was perfect. It is just really hard to remove the old one and install the new one. It took me a few beers and hours.

Tube is great, but changing it out was difficult. Two valve stem styles, bent and straight.
I bought the two pack. The tubes are excellent. Nice and thick. Make sure you notice whether you need the straight or bent stem. It's worth noting that tires this small can be very tricky to repair because of the diameter of the rim. I ended up bending the rim on my dolly, but it still holds air just fine and the hand truck works the same. Bottom line: great replacement tube but difficult to install without knowing the trick to it. On larger tires, the perimeter of the tire should pull to the center of the rim, allowing the tire to slip off of the rim on the opposite edge of the same side (I used two large screwdrivers for leverage.) This didn't work for me, however, and I ended up bending the rim. The only reason I shared that is for awareness to DIYs. The product is an excellent replacement for a tube that can't be repaired, but be ready for a small challenge if you haven't changed the tires on one this small.

Good product.
Good product at a great price. Much better to add a tube than buy new tires for a little used piece of equipment.

If the tube fits...
These inner tubes are a perfect replacement for my yard cart wheels. Not all tires are the same, so be sure to read the side of your tires before ordering.
