restoring

I've just about looked at the web all I can handle trying to find accurate information on the 2013 STX 4x4 wheels that came stock on our truck.



So far I've found someone stating the backspacing is 44 millimeters. That equates to slightly over 1.7 inches.

Another source claims the backspacing is 5.5 inches.

And as usual, the dealer is less than helpful.

I'm trying to figure out what the backspacing is so I can ditch the Goodyear SR-A's and replace them with a more off road capable tire.

I'm also trying to find out how big I can go on tire diameter without rubbing or screwing up something on the truck, but as you can guess... the dealer isn't helpful there either.
