Man I'm sorry to hear about your bad luck with this tire. Zero problems with mine thankfully. The shop that installed mine balanced it, then I added "Ride On" for puncture resistance and balancing.
It seems like manufacturing and shipping are both falling apart right now. I'm told tires for Bushtec trailers are unavailable and may stay that way for quite some time. No one seems to have enough workers and there are/were shortages of some basic items necessary to industry. I don't know that this has anything to do your problems with these tires but it might. I've certainly seen a drop in quality and timely arrival of many items needed in industry.
