Mission AutomotiveReplacement Tire Inner Tubes - 2 Pack - Fits 4.10/3.50-4 Inch Wheels - Great for Wheelbarrows, Dollies, Lawn Mowers, Yard Trailers and Other Outdoor Equipment

For my beer or candles if you are having a major shindig or Soirée and need cool stuff floating around in the pool.Or you can use them to fix a flat tire.Either way you’re covered.

These comments are no reflection on the quality or design of the inner tubes. You would think that putting tubes in a 4.10 x 4” tire on plastic wheels shouldn’t be much harder than thinking about it. You’d be worng, but once you figure out how to do it, the second one takes about 1/4 the time. I bought a 3200 psi pressure washer from Costco several years ago. It came with tubeless tires, so almost every time I rolled it out of the garage, the tires were flat. It was a pain in the butt to get air into them. For instance, I fought filling them in May, putting a little extra air in. Last week, August 10th or so, went to use it again, and both tires were flat again. So, I had bought the tubes, and was ready for battle. I used bicycle/motorcycle tire irons to get the tires off and on. I needed 3 irons to get the tire off, leaving the first one in place to keep the tire bead at the starting point, then alternating the second 2 prying the bead off in steps until it rolled off the rim. I didn’t take the tire completely off. Then, once the tube was inside the tire, I found if I clamped a Vice Grip pliers on the rim where I started rolling the bead back over the rim, it kept the tire bead from following my efforts with the tire iron around the rim, and only one tire iron worked best in the reinstallation. In the future, the tire pressure may be low after sitting through the winter months, but with tubes it will be a cinch to air up the tires, instead of fighting the beads back on trying to seal them long enough to hold a little air.

appear good quality fit right in

I've had a dolly for the better part of 20 years. I don't use it all that often, but when I did need it, I had to inflate one of the tires (which would not stay inflated). I finally got tired of dealing with it and looked into repair options. I could buy a new set of tires for around $40 or simply add new tubes to my current tires for around $15. The tread on my tires were in great condition so I went with new tubes instead. When they arrived I removed the axle shaft caps from my dolly and saw that the tires were held on with star compression washers that once removed, cannot be used again. After getting the tires off, I was completely frustrated trying to get the tires over the rim without proper tools so I could put the new tube inside. After about 30 minutes I gave up and took them to my dad's house so he could use his tire changer to help me out. With the new tubes in the tires, I decided I would just use a standard washer and cotter pin to secure the tires back on the axle. My dolly did not have pre-drilled holes and I destroyed 4 drill bits trying to drill through the hardened metal of the axle shaft. I got on Amazon looking for plan B and found these axle shaft collars for $10: https://www.amazon.com/dp/B07GSTTZMS?psc=1&ref=ppx_yo2_dt_b_product_detailsI now have a fully functional dolly again.

Tubes that hold air are important. These do that. So, yay.

Held air I'm pleased..

These are great quality and way better for less money than at Lowes or other hardware stores.

work great and the valve stems can be tightened to the rim to prevent the tube from slipping inside the tire.
