Default Larger Rear Tires

Hey guys, I was wondering a few things about having larger tires in the rear.

First off, I am driving a 2002 4WD 4D Blazer.
Does having larger rear tires screw up 4WD?

Also, I want to buy all BFG All Terrain T/A KO's and have 30/9.5/R15's in the front and 31/10.5/R15's in the rear.

Doing this would screw up the caster angle a little, but enough to matter/damage anything?

I'm only doing this because I am going to get 2" shackles for the rear and most likely not crank my torsion bar at all since I don't want to risk ruining any front parts faster than normal.

Anyway, thanks for any replies.

You can run larger tires in the rear and be OK, technically. However, DO NOT put it in 4WD for any reason unless you are in really loose sand or a similar environment as your front tires will try turning faster than your rears and you will break stuff.

I'd either just go with the smaller tires (as larger/smaller tires on a 4x4 looks goofy IMHO) or crank the t bars a little so they'll fit.

Well, I just really rather not crank the torsion bars because I only bought this Blazer used last year and I don't know the condition of any of the front end parts and I definitely do not have money to replace any of them.
Plus, I don't want to shell out the few bucks for an alignment anyway.

The tires are more or less a fantasy for when I have money (I bought the Blazer with brand new tires on it, so I am good for a while).

Most likely I'll just wait until I can get a 3" body lift.
