I went and got two new Akuret 9.5l-15 tri-rib fronts. two guys mounted them with new tubes. One guy was done quick, the second cursed and struggled with the tube??!! Went out a few hours later at home and that one was flat (hadn't even put them back on tractor). Took it back the next AM. The boss broke it down. The new tube was split open half way around the inside. No explanation, maybe cheap china. I found it odd that they squirted mineral spirits not only on the bead but very liberally inside the tire so the tube will "slide" around. I always was taught to use talcum powder. I don't think the second guy filled the tire and let it relax befire putting the core in. Just my tire story any thoughts?
