Thanks all for your input!
$$ is tight, but, I'm thinking that it might be best for me to spend the it on new rims and not have to worry about this anymore. At least I don't have to worry about buying a whole package - my 16" tires were all seasons bought this past summer. I'm looking at some painted rims with maybe a chrome lip or inserts or something. Something chrome decorative and less likely to mess with the function of the rim. As a first time mom, as much as I love my PT, I have no time to fuss with this aspect of it anymore. I spent many days last summer hugely pregnant and in the local tire shop replacing tires, then valves (3 times + 1 time near my job when I came out after work to a total flat tire). Why did no one suggest the sanding process I now keep hearing about when I was there <_<
Any way - Thanks for the info on the bolt pattern and possible deals. Hopefully when I get the new rims I can come back and post a pic!
