After the dealership, the steering wheel was misaligned to the left slightly
I don’t know what you describe as “slightly” but if the alignment was done correctly and there are no worn or damaged components.
The steering wheel should have been set straight.
If this has been the case since the issue began, I would consider the front end improperly aligned.
When you had the tire shop do another alignment was the steering wheel still off center?
You’ll need to first confirm that the front end is within alignment specs.
My suggestion would be to find a shop who’s specialty is alignments and tell them what has been happening.
If it turns out the front end is with in specs then your dealing with a tire issue.
If the front end requires adjustment(s) and/or component replacement.
You then need to see if the vehicle still pulls and if so you’ll need to move forward to seeking tire replacements
