It's very difficult for a novice to determine the correct wheels required to suit a particular vehicle when they attempt to use 'offset' as the critical parameter. The specification is always dependant on wheel width which more often than not causes more confusion for those not proficient with wheel specifications. I recommend using "backspace" as the critical specification when attempting to find the ideal wheel for your particular needs. Firstly know the backspace of the stock wheel for your model and with the stock wheel on the vehicle measure any critical clearances essential for full articulation and at full lock in both directions. backspace is constant regardless of wheel width, so you should be looking at clearance to inner guard (or control arms, etc.). The other parameter is what width will allow the vehicle to articulate fully without hitting flares, guards or mudflaps, etc.
I'm happy to provide a graphic comparisons to show the effect of changing to wider wheels based on backspace alone or width at a specific offset.
When using offset alone, most end up with a wheel that will not perform as intended and in many cases live with this compromise as the cost of that mistake inhibits further correction.
