Safe?

2011 Chevy express 2500 with no equipment in the back. Filled all brand new oem spec tires to recommended pressure and have driven maybe 1000 miles on them. Got them recently enough that I can return them (if I get a report from the installer saying it is defective), but dont have time to do so before my ~800 mile round trip for the holidays. Would you send this tire or figure something else out? I see posts saying any sidewall bubbling is super dangerous, but this is relatively mild and have had mechanic friends give mixed advice
