Is it worth getting a second opinion about getting my car safety done?

I just got mine done and they said it needs like $800 of repairs on top of a new set of tires because apparently the tires aren't the right size. This is just a lot of money I wasn't expecting I would need to spend so suddenly. Would it be worth it to get a second opinion and see if I don't need to spend that? I don't want to spend money on another safety just for them to tell me the same thing but I also don't want to have to spend money on repairs that aren't actually needed for the safety.
