Bad tubes
I just tossed some Teravail tubes (27.5 x 1.5-1.95) in the trash. I installed one in a Panaracer 650b x 42 tire (53 psi) but within hours the tube split on a seam and left me flat. It was not ridden, it just went flat in the garage. Repaired the tube and in a few hours it went flat with the same seam splitting. I tossed that tube and a new in the box Teravail tube, into the trash. These were bought in May 2021.
I don't think I can trust the off brands. These were made in Taiwan which seemed a better bet than the Chinese ones.
Have others experienced this problem with off brand or name brand tubes? I can't remember this happening before no matter where they are manufactured.
