Thanks @mjm-1957 , much appreciate your help and advice.

Good question, I did this out of ignorance as the same size wasn't available. So checking if 1-inch variance will cause trouble with 4 high or 4 low?

I lifted 2 inches of the 2009 Trailblazer LS last year to install bigger tires 265/65/R17 (rare size tires) for off-roading. Recently after experiencing a puncture, I changed the rear tires to 265/70/R17 (easily available size). I know this minute difference is fine for 2W and 4 Auto but will it cause any issues while off-roading in 4 High or 4 Lo? Does the 2009 Trailblazer LS with a 4.2 engine have 50/50 lock at the central differential? Thanks in advance.
