The factory 20's on my 05 ram are no where near as heavy as 22.5's. My factory 20's are around 85 lbs a price, from what I could put together on the web a 22.5 tire/ wheel package is probably double that at least. An acquaintance of mine had the whole 22.5 deal on a 3500 ram and ball joints/tie rods/pitman etc replacement was a yearly job.
