I just found a set of 20 inch alloys for sale that would fit my van, currently has 16 inch steel. They look like normal tires on them, not low profile, I doubt they are any lighter but I was thinking this might give me a higher gear decreasing my rpm at cruising speed improving fe. I am pretty sure they would fit in the wheel well, my concern, would I be stressing the front end, transmission..do you think this is a valid concern, any other pros or cons???
