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.

Worked great to replace the slowly-leaking tube on my hand truck. Bonus, I got an angled valve stem as a part of it to make refilling easier - though in the 2+ months since I replaced it I have not noticed any air loss. I knocked one star down on ease of installation because it was anything but easy for me. Fully deflated, half limp, inflated to roundness, none of them made the job easy. But I’ve mostly forgotten that since I no longer need to refill the tire every time I need to use the hand truck.Update February 2021: I haven’t added any air since the original installation; they are holding up just fine. Definitely worth considering if you are in the market for this product.

Seem heavy duty . . . thicker material than the tubes I’m replacing. Would be a bit better if the valve stem was rotated a bit to the outside . . . Valve stem holes in tire rims are offset from the hub area of the wheel. Otherwise it fit and installed OK. Haven’t had these installed long enough to rate durability.

These are perfect for a garden tractor cart.

My rototiller has been buried in dirt for 30 plus years, motor frozen tires flat, seemingly unrecoverable, I was wrong shes back in the dirt again, and thanks to the tubes rolling instead of buried, thank you

Arrived on time and fit perfect. They seem like good quality tubes.

I ordered these twice, a year apart. The first ones have held air for a year. The 4 cheapo tubes that came on the roller hose real all went flat.

Kayak dolly came with a punctured tire. Amazon seller did not respond so he got a poor rating and I got new tubes. All good now.

Great price and easy to install

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

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

I was unable to use these in my dolly as a replacement, but the return service was great! They accepted this item back with an explanation and little grief. I would recommend their service to anyone.
