The wheels that come stock on the ram vans, both the 15's and 16's are often listed as 15 or 16x7 also, but they are really 6.5. There are usually some wheels for sale on ebay but I want be sure of the dimensions before I buy. I do have some good news though- I found a set of springs that will fit. Apparently the leaf pack in the 2000 ram wagon (my van) was not the same for all models that year. The conversion van (my is just a regular passengar van) had a 5-leaf pack whereas mine has only a 3. So, looks like I found what I was looking for there. Not sure that it will change the ride height by enough to make a difference for a larger set of tires though...
