2 Pack 3.00/3.50-8 Replacement Inner Tubes with TR4 Valve Stem for pneumatic wheelbarrow wheel,cart wheel, garden cart, wagons - Made From Heavy Duty, Thick Premium Rubber

Great tubes, tough! HOWEVER, take note that the valve stem is on the center line!! Most wheel's/hubs have valve stem openings offset from centerline!

I read the review of some of the cheaper inner tubes, and decided to spend a little more for a good tube. This one came quick, in perfect condition, and I installed it the next day. Everything went perfectly.

Update: These do not hold air long term, even in storage. Just poor quality rubber.Decent discount tire tubes from China. These were a bit thinner wall thickness than the originals in my hand cart, but did the job. The originals also had metal bent valve stems, but as these were offset from center (as shown in the picture), I took a chance. They worked, but had this been a newer handcart that gets regular use, I would have sprung the extra three bucks for the metal valve stems. Also, they claim to be up to 4 times thicker than other brands, but I seriously doubt that.

Purchased and installed this tube. After two weeks, it went flat. Upon disassembly, I see that tube had rot and leaking from the rot area. No puncture hole, just a small area with rotten rubber. This should not be the case for a new tube. I know these tube do rot after few years and leak. But shouldn’t happen to a brand new tube. Very disappointed.

Item shows metal valve stem. Came with rubber ones that were way smaller (diameter) just flopped around in the hub. Both tires had leaks in them. Totally worthless. Save your money and buy another brand.

The brass stems, I have been looking for a couple of years for these. I have a 4 wheel utility wagon with metal wheels that keep chewing through the rubber stems and going flat. I am an old fart and knew these existed but could not find them. Farm & garden stores, auto parts, big box, even E bay & Amazon, nobody had them. And then one day I decided to try again after another flat and here they were.Awesome!!

I watched a couple of YouTube videos to get an idea of how to accomplish this chore, but it turned out to be far more difficult than the videos showed, and it must be said that videos advised it WOULD NOT BE EASY!But, it finally was installed and seems to hold air. Can't comment on durability after a month, tho'.

It had a hole in it (right next to the stem) after I installed it.Was the hole there before , I'd bet it was not.Crap tube, maybe.My fault, maybe, but more likely.So should I refrain for reviews that don't help ..... YES (they only thing I'm sure of)

i replaced the tubes on my snowblower and within two weeks both tires were flat.the seams in the tube split a part and no i did not over inflate them.thk you Bill

These are better than any other brand name that I have used before.They are half the price of the main brand.

This product was exactly as described. Shipping was quick & the quality was good. Would definitely deal with this seller again..

Pour mon pneu de brouette.

Good value
