Both.
Specifically, this question was sparked by a "debate" (read: argument) over whether or not installing over sized tires required a new alignment.
In this particular case I am referring to a wider and larger diameter tire mounted to a monobeam axle; that is a mud tire on aftermarket...
As the title says, how will installing a larger tire/wheel combination or altering wheel offset change the alignment with respect to caster, camber, and toe?
I know that the parameters are affected, but I cannot verbalize or visualize these changes. Feel free to use big words and jargon.
TIA!
