How to determine lift needed for tire size

If this is a question already answered elsewhere, please point me to it. I know with my standard suspension (2014 Tacoma Limited) I can go as large as 265/65/18. I've currently got 265/60/18. When it's time for new tires, I'd either go with 265/70/18 which has a 32.61 diameter, just over 2" larger than my current tires, or 275/70/18 with a 33.16 diameter. How can I find out what lift is needed for each size?

 

Lift has nothing to due with tire size.

Thanks, that helps a lot. Gives me something to think about on the next set!
