Looking to change out the rims and tires on an '02 I just purchased, on the van now are no name brand 20 " rims and tires and I want to switch them over to some 16 " Michelin. I have 4 - 16 " factory rims on my '03 I want to install on my '02 but I am not sure what they are constructed from, or the finish. Does anybody know what material is used in the construction of these Dodge 2003 Ram Van factory rims, and the finish ? I am assuming these are factory rims because I have seen these type rims on several Dodge vans. I thought I have read somewhere that these are ' alloy ' rims, but then they rust in spots, however the rust comes off easily with a scotch pad and dish soap. I would like to clean these ' alloy ' rims up before I have tires mounted on them but I am not sure what would be involved in cleaning them up (wire brush, sand blast, paint). I found 2 - 16 " chrome rims at pull a part (25.00 each, with tire), but I only have 2 of them, not sure I will be able to find another 2, or the price. I have always liked the look of the ' alloy ' factory rims and that might be what ends up being installed, however if I had 4 chrome rims. Also, does anybody know what solid one piece chrome lug nuts work with the factory center caps ?
