Seems like everything that is rubber, is outsourced to China, Taiwan, India, ect. Our good ol American rubber I've seen in pretty doggone good shape after 40 years or so (not speaking of tires), and I've seen this new stuff (even though these people don't have the regulations we have here at all) just produce garbage, that turns to crap, within a couple of years. I remember when I was younger running 20-year-old tires on cars. For a tire that new to blow out to me that's unheard of man that's just crazy
