Do you ever haul loads? Go out into the mud? I got 16" rims because I didn't want to change my trucks lift or level, and (since my truck is multi-purpose) I wanted to keep the highest tire profile I could possibly have. Larger Rims with lower profile tires would have looked a LOT nicer on my truck, but hey, I'm one of those wussies who feels that form follows function. My personal choice is for a truck that looks less cool, but has the ability to do a lot more.

If you're not doing any urban-terrain-defiant maneuvers,(hello-there) such as going over steep curbs with pallet loads of material, and you constantly stay on the pavement, then welcome to the world of "Size-Up"-Google it. Did I mention that as well as proper sizing info, many custom rims sites can show you what a vehicle like yours looks like with the new rims?
