I read 3 reviews about this Larin tube, 2 of which gave little hope. I drove the 12 miles to my local Tractor Supply and purchased 3 4.80x8 tubes for my boat trailer, hoping to avoid the needed second trip to replace a defective tube. The two I used work like champs. The name on the box is not Larin, but rather Traveller. Also the number on TSC webpage is 031115099, but on my packages 031150. Same price.

Very disappointed in TSC for selling these tubes. Bought them because they were specifically for boat, etc trailers. First tube split as soon as I tried to add air. Thought I might have done it while installing so I was extra careful with the second tube. Got it in the tire and aired to 40#. When I went to 50# the tube blew out on what looked like a seam. There were no inflation pressure guidelines on the box or the slip inside. New tires were rated at 90# but I have a very light load so I was going to hold at 50#. Old US made tubes were still good so in they went with no problem and are working fine.
