Totally Confused with New wheels today

I have a 2010 TRD Offroad w/factory 16" wheels running the factory 265/70/16.
I went to Discount today and picked out wheels that I liked and told the guys that I may put a slightly larger tire on the truck when the rugged trails wear out.
I was in a hurry to get to class this evening and the guys at the shop knew they were running out of time so they finished the install and I hauled A _ _ to class. When I came out of class it looked like my tires were sticking out about 2-3" past the body of my truck.
I had my old rims in the boxes the new rims came in so I looked at the boxes and the rims are:

16" x 8.5" with zero offset.

How much does this make the tire stick out farther than stock? is it an optical illusion ? I will look at it in the daylight again in the morning but I think something isn't right with the fitment.

Please help with advice

 

That's a good look imo

 

the offset on stock rims isnt zero

 

uuhhh... im more familiar with backspacing. Most of our aftermarket wheels are 4.5" backspacing. This means there is 4.5" from the inner most of the wheel to the hub of your wheel (where the lug nuts attach). So with a 8.5" wide wheel, u will have a 4" dish which would seem about right. Check the backspacing. The less the backspacing, the more the wheel will stick out. 4" bs may be a little extreme. 5" bs may not stick out as far as you would like.

 

ya jhodge is right

 

I have 3 questions:

1. So if the stock rim is 7" wide and my new rims are 8.5" wide and the zero offset pushes the wheel out .75". Then the two items .75" and the extra 1.5" from the wider rim = 2.25" further than stock???
2. I was told that the stock tires on a 8.5" rim would wear quickly because they are too narrow for an 8.5" rim.
3. What would be the proper width tire to fit properly on an 8.5" rim?

I know these questions seem a bit panicky but its because they are. I bought the rims yesterday and need to have the right info on whether to exchange them and if yes then what size to go to. I will have to do something tomorrow or it will be to late for an exchange.
Thanks, Guys

 

I think most people go with 285 wide tire with that wide of a rim. But that will require some trimming to not rub with the tires and you will also need to lift (if you haven't already).
