American Racing VF490 20's Questions

[Ardee83]

It has been a long time coming. I have gone back and forth between wanting 15's 17's 20's, but I have finally decided to purchase some new wheels for the truck in 20's.

The wheels I am going to pick up are the American Racing VF490 wheels, I love the deep dish on them. But here is where I run into issues.... I have never purchased a set on wheels before in my life.

So what I need help with is the following.....

Truck has a 2.5/4" drop

I want 20x8.5 up front and 20x10 in the rear. So bolt pattern is 5x5

Next question and the one that seems to be most asked is backspacing. I want the rim and tire to set inside the wheel well, I like the way N2TRX rims fit his truck. So what back spacing do I get?

Next question I would need a set of tires to go with the wheels any recommendations here? I would still like a thicker tire, no low profile

As always the help is appreciated
