I was looking at rims on this website
http://www.rims-n-tires.com/rt_packa...rModel=300+RWD
and noticed that they have a "Fitment Guarantee" for the 5x114.3 and 5x115 bolt patterns. So I sent them an email telling them 5.114.3 is not a correct bolt pattern. Below is their response.
----------------------------------------------------------
Hello,
You are right, 300C has 5x115 bolt pattern,
exactly as it states on the web site (see specs in the top menu):
http://www.rims-n-tires.com/rt_packa...rModel=300+RWD
However, 5x114.3 (5x4.5) is a correct fit as well, just slightly tighter
(see comments under packages).
Besides market offers MUCH wider choice in 5x4.5 bolt pattern.
Also, all our recommended (direct fit) packages are backed up by our Fitment
Guarantee:

So, order with confidence.
We know what we are selling.

To summarize their response.
Yeh, we know it is not the correct fit (slightly tighter). But because there is a MUCH bigger selection of wheels with 5x114.3, we think we can make more sales/profits by claiming the 114's will fit. But trust us, see our fitment guarantee. You have nothing to worry about, even if you start to develop vibrations 6-12 months later, as your wheel starts to crumble under the stress.
Felt I needed to post their response, as it irks me some wheel sites are intentionally, or misguidedly, making incorrect advertising claims.
