I bought four of these for my garden cart. These are good quality and I like the ninety degree valve stems (see photo) – makes it easier to inflate them. Four months in and they are still holding air pressure. Basically, they are doing what inner tubes should do – what else can I say?

They want a review on tire tubes. Really! I’ve got an old beer dolly “right”, and I’ve had it for over 40 years. I have never change the tires or tubes on it. I just wish I knew where Budweiser got the dang thing because it has lasted so long. By the way it fell off their truck right in front of me on the freeway and he kept going. Well let’s just say this, they are tubes ok. I can’t tell you how long they will last, or if you can easily install them, or if it is a value or not. So call me and in 40 years, and if I’m still alive I will let you know. M

These are great tubes at a very fair price. I used them to repair a moving dolly. The difficulty of installing is because of the TIRE, not the tubes. It is a little easier and much safer to use real tire tools than screwdrivers which can easily puncture the tube. Also, to reduce the chance of pinching the tube, inflate the tube minimally before seating the outside bead. Dish soap helps the tire slide over the rim.
