I bought two of these tubes for a Tartar 36" UTV disc harrow purchased at TSC in 2014. Even when new, the OEM Chinese inner tubes would not hold air, and I resigned to filling the tire before every use. I recently bought a bottle of Flat Out from TSC to stop the leaks. It did, but it made the tubes stick to the inside of the wheels, and the flexing of the tire sidewalls ripped the valve stems out of the dry-rotted tubes on the first use. Before the next use, both tires were flat and off the rims. The new tubes are Chinese low quality, poor material exact replacements. I reclaimed the Flat Out and added it to the new tubes after installing them. For comparison, I have a hand truck with US-made tires and tubes that were made in the 1970's that still hold air for over a year. There is no money saved by purchasing imported junk that fails before a reasonable service life. It's incredible that people put Chinese tires on their cars and trucks.

Shocked these tubes are 2x as much as what you can get for your airplane that hold 70psi. But if you need one asap, TS has you covered.

I have gone through 4 of these in the past 2 years, used in a DR Powerwagon, they blow out within about 8 months. Yes, I have them inflated to the proper PSI, they are simply garbage!

I paid twice as much but it was in stock and the little Deere rolls again.
