Tube failures
I wrote a book ( at least it seemed like it) a while back on this very issue. Inner tubes will decay in time. I received several new tubes for customers aircraft that were folded,then rolled and shoved in the rim holes. While unpacking them I noticed cracks already forming in the folded areas. I returned all of them for replacement. I reordered and received 4 that were packed the same way. I used three on my 6a and had two fail in less than 6 months! I'm going today to replace another tube after a failure on his 8. I ordered stock tubes from Spruce and requested they not be folded....these looked great and weren't folded like the others were( different vendor) . My advice after 37 years in the business....don't skimp on tubes, if your building an airplane..wait and order your tubes when you're close to being done . Use plenty of tube talc powder when mounting the tires/tubes. Keep tire pressures up as constant flexing of side walls will also weaken and work harden the rubber in the tires and tubes.
