Hello with all my experience…
Hello with all my experience working cars, equipment, heavy industrial equipment, and pretty much anything that has a motor in it. I'll say 100% sure they were torqued way to tight by the way they broke off. And all of them broke. I broke enough bolts and studs in my life to know what over torque looks like . Not by meaning to but a bolt and stud can only get torqued so many times . And if wheel was loose he was going down the highway with a load. Come on get real now you would definitely notice if you had a loose wheel. Especially when he said he does it pretty much everyday. Definitely torqued to tight and really torqued to have that happen.
