Rack and Pinion steering does not have an "inner tie rod end".
Just an outer tie rod end on either side for a total of 2.
You are not creating enough 'G's to be sucking air at or just below the 'ADD' mark.
One size bigger in relation to the stock 215/65R16?
What size actually?
If they were rubbing, they would be rubbing like
the pics show.
btw, those are 275/40-18s on a V6 with slight rub but
who turns lock to lock anyhow? the turning radius is so tight
on these v6 S197s that the ends of the steering travel should
never be reached during normal everyday driving...
