When I look at the tire comparator the 235 adds .7” to width and takes .8” off diameter.
So split those two in half and the tire moves back .4 and out .35. And you are hitting the tire turned at an angle. So going back near the same as out cancels each other out .
Something like 215/65/14 or 225/60/14 AND something else.
IMHO moving the tire away 1/2” more than now is not enough to protect a new paint job like that.
What was the caster spec from the alignment you got?
What strut rod bushings do you have?
