Will it fit?(wheel with adapter)
I agree, nothing wrong with quality wheel adaptors or spacers. For adaptors that usually means at least 1" thick (minimum 3/4") and made from billet, not cast aluminum. Those little cast jobbies they made back in the day that go from 5x4" to 5x4.5" are bad news. And preferably hub-centric if possible. Yes, I have seen billet adaptors that have failed. You still have to make sure they're torqued properly, especially when they're first installed. That means taking the wheel off and torquing the adaptor lugs to spec a couple times over the course of a few hundred miles (just like new aluminum wheels are supposed to be!). Like anything else if not used properly they can fail.
Like these. Nothing wrong with using an adaptor like this IF you have the backspace to allow it and you torque them properly and follow up
NOT THIS. This is death on a stick. I've seen all kinds of these that have cracked. Doesn't matter if you do it right, these are a time bomb.
As for the OP's original question, no, I don't see that working. Without the spacer the backspace would be about right for that tire, maybe already on the shallow side but workable. With the spacer there's no way those will fit, you'll be 3/4" outside the quarter.
