Um 275/60r20 is a factory Tire size.. it's a 33x10? Or 11? I don't recall exactly. So it would fit regardless.
A 33x12.5 rubs because of wheel offset and width not height. 275/65/20 is a 34-34.5 depending on brand and tread, also fits factory height. Will catch wheel well liners if they're muddy and hanging low, driveway approaches etc. But that's an extra inch of Tire.
275/60/20 you're doing a lift or level purely for aesthetics or you have an offset that is causing issue with aftermarket wheels.
Finally got around to setting the links and having it aligned. Went 1.5" in the front so there is no rake. I thought about leaving 0.5" but figured if I want I can lift the back a little without feeling like the front is diving in the future. before:
