2Pack 3.50/4.00-6 Tire Tube with TR13 Straight Valve Stem Fits 4.10/3.50-6 13x4.00-6 13x5.00-6 145/70-6

I needed these for leaky tires on our garden cart. They are a perfect fit, were relatively easy to install and so far, seem to be performing well. My fear was that I had grass burrs poking through the tire itself that would immediately cause a leak in the inner tube. So far that's not the case. After several days they are holding the air just fine. They feel heavy duty and fit my 3.50/4.00-6 size wheel/tire assembly perfectly. In the few days I've had them, they have performed well whether hauling groceries from the garage to the house or hauling firewood behind my riding mower from the back part of the property. I'm impressed at the quality they evidently have. I have more carts that need tubes, so I'll certainly be ordering more in the future. These were priced well below what I could purchase replacement inner tubes locally for, plus were a good price compared to other choices on Amazon.

I ordered four tubes for my son's wagon we are restoring. One of the tubes had a something wrong with the valve stem and wouldn't hold air. This can happen from time to time. I contacted the seller, they responded very quickly, and they offered a refund or replacement. I asked for a replacement and they sent another tube and it arrived in just a few days from my response. The rep was very friendly and got the problem solved very quick. The replacement was perfect and now I have the wagon back up and rolling. Thank you so much for a wonderful, stress free experience. The tubes really are a great value and made very well. Very durable. These things can happen from time to time and should not reflect on the seller. They did an awesome job to make it right.

After spending more money for a pair of tubes from a company that I did not know, I sent them back because they split at the seam when inflated, I purchases these. I mounted them by hand, which was not easy for some one my size, then inflated them to 30 psi. It has been a couple of weeks, and they have performed well. Tires have not lost any air pressure. I am satisfied with these tubes. Mike Smith

They worked great and fit just like the originals! I wish they would have come with a pouch of talcum powder to coat them before installation inside the tire - it helps with movement while the tube is being inflated/deflated.

Great construction long lasting

Good quality, true to size

Perfect fit to replace Razor scooter tire that had gown flat. Installation was easy and you can tell this was a durable replacement.

My Scott fertilizer spreader had a flat tire. My son kept using it while the tires were flat, which caused the inner tube to grind into small pieces. I couldn't find a replacement inner tube at any local store, and I thought I would have to buy another $80.00 fertilizer spreader. However, I found one listed on Amazon that came to the rescue. It was the cheapest option available, easy to install, and worked like a charm. I have to admit, the first one had a leak, but I exchanged it for another set and it worked out fine.

These tubes are for my garden cart which always had a flat when I wanted to use it

Tres bien

These tubes were easy to put in my scooter tires, and the price is right.

Good price

Great price and easy to install
