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 both 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.
