The big hole in the middle of the rim is the center hub hole and it fits on the hub of the brake rotors. A Hub Centric Ring is used on a wheel where the hole is too large for a particular application. The HCR is used to make the hole smaller. All car makes have a different size brake hub so Wheel companies make one size hub hole on their wheels and use a HCR to make it fit. For example - The Wheel company makes their rims with a generic size 75mm hub hole but to fit that wheel on a car with a 65mm hub they have to install a 10mm hub centric ring, thus reducing the size of the center hub. Hope this helps.

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:
http://www.rims-n-tires.com/info_ourguarantee.jsp
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.

Can a 114.3 be machined corrctly to a 115? I am looking at the tsw 20x8.5(Kayakami?I think) whichis a 114.5. The shopassuresme the work canbe done toconvert the pattern to a "true" 115. Is this possibole, and ifso, how. I amsure running the 114.5 initailly would create little if any discernible issues, but the long termwear and tearis sureto create problems down the road. I'd appreciate an informed response tothis to take back tothe dealer, and to callTSW as well.

I would run and not walk away from the shop who suggested such a thing, let me put it this way, if you did have some problem with THE MACHINED parts whose fault would it be? YOU and no one elses. Sure the work could be done but it would never be correct. I think your life and the lives of your family and friends are more important than some remachined wheels. Man I think I have heard it all. Continue to run Please and have a safe holiday with the correct wheels from the start. If you want to live dangeriously invite the girlfriend over for the Christmas meal with your wife and inlaws.

Then there are other websites, where the 114.3 does not show up as a correct fit, such as bigwheels.net. I call Tireworks and other wheel shops, and they say 115's only fit.
It is my understanding the 114.3 is not the right fit and not to buy this size.
Are the folks buying the 114.3 using hub centric rings? Or could they be living with wheel shimmy at certain speeds?

If the bolt pattern is 5x114,3 and you have a strong metal hub centering ring, you will not have any problems, because the centering of the wheels is not bolt-related at all. The wheels will stay correctly centered after proper tightening of the lug nuts, no matter how you drive.

I also have no problems.

My 4 decades of performance driving lead me to disagree with your claim. The center hub was never engineered to center the wheels. A slight error of even a millimeter there multiplies as it moves out from the hub. The lugs are designed to center the wheel and hold it firmly in position. The wheel must line up perfectly on the lugs. 114.3 mm wheels do not line up on 115 mm lugs.

Hub centering rings are not the right way to solve the problem. Once vibration starts, it almost always gets worse.

Many years ago, I felt the right front wheel and tire vibrate violently then roll down the road ahead of my car as I rapidly descended a hill on a busy 2 lane black top. Soon the right front of my vehicle dipped, throwing my car into the path of a large Semi 18 wheeler. By the grace of God, I hit the opposite shoulder and eased into a ditch - a fraction of a second before the truck barrelled by.

Why did the wheel come off? I had oversized the wheels with mismatched rims and one wheel vibrated loose. No part of the car takes more stress than where the wheels are bolted to the lugs.
