Larger tires will INCREASE the toe-in, which is usually OK-
Larger tires will not change Caster, however lifts will and with the larger rotating mass, of tires, the caster can be VERY important-
Installing a lift and big tires, doesn't always require a caster chg and sometimes an alignment isn't required--
Your first driving experence will tell you of the condition-
I lucked out with my lift/tires-I didn't require either alignment or caster adj-but that is the exception, rather than the norm !
