| I'm pretty sure the magic numbers you are looking for are 72.56 to 74.1. I'm guessing you may have e39 bmw rims which you are trying to use on your e46. Posting a pic of the rims would help. They make the rings for a reason. I've never used them, but yes they will provide the support you need. Just make sure you buy the metal ones. They make plastic ones, but they are way too close in price to not justify simply upgrading to metal. If this is your case you can see how many options you have: http://www.ebay.com/sch/i.html?_trks...at=0&_from=R40
