I recently had my car aligned and once I brought it home I notice that the back tire were v'd outward and on the front they are v'd inwards. Is this the correct tire stance or should I bring it back to the alignment shop?

 

two things - 1) always ask for the print out from the alignment that will show factory settings on top of the measured - both before and after the alignment. 2) when you say V inward are you talking top to bottom or front to rear?

You can google for your model's factory spec for camber - this is the angle of the tire to the road or toe - this is the angle of the tire center lines comparing left to right. There's also caster which is the angle of the suspension's up/down travel. Most cars have a slight amount of toe in - with the fronts angled in slightly more than the rears - this is to produce a solid on center feel and return.

BTW, taking a 2010 XC90 as the example, the front and rear toe-in are both .3 degrees so I'm not sure if you'd be able to visually see that. For perpspective, that translates to the center line in the front of the tires being about 3/10ths of an inch closer than the back side of the tire (ie measuring from 3 o'clock to to 3 o'clock then compare to measuring from 9 o'clock to 9 o'clock).

My advise is see how the car drives. If it pulls to one side or the steering wheel is tilting or the car doesn't track straight, bring it back to the shop and ask them to measure the toe in and thrust angle and provide the print out to compare vs factory spec.
