Wheels, considering going 17"

I personally like the look of the welds like in your picture. However if you work it out right and fill the fenderwells up with enough tire I think the 17inch can look good.
That may be a slight problem as the 17 inch tires are usually 25" and smaller. I think 26" would look nice but anything smaller than 25.5" in dia. would not fill out the rear fender wells
