Who's Duster? What Tire/Rim size?

Not mine, but those wheels look like stock Rally wheels. I would guess they are 15x7s with a 3.75 backspacing, that or 3.25 backspacing. Which ever backspacing is stock.

Not on the front right? (I'm pretty sure those are 15x7 with 4.25 BS).

Did you mean the rears? (I'm thinking the rears are 15x8 with 4.5 BS).

Thanks for your input!
