Do not talk to the manager. Go fill out a small claims form. Send this as instructed by the form to the store. Does not matter at this point what mich says or does not say. If the warranty is voided by improper installation and you can print that out then go with that. It is enough. Do not argue with the walmart moron he is not a lawyer and he has no idea how much trouble he is in. He will lose his job.
You are not paying attention. Walmart installed the tires. Go to the small claims court and fill out the form. Mail it. The manager will be gone. The effect is not the issue. It is the claim of the MF that improper installs throws away $100 per tire. Wake up and put in the claim!
That would work if the rims could be put on from either side. I have never seen one since they switched away from wooden spoke wheels with demountable rims. How many have you seen?
