I am wondering if any members on here run 5x114.3 on there impalas that have 5x115 bolt pattern and if so have any had any issues.

Thank you

I do not run 114.3 wheels on my car, but for what it's worth I must place my vote in the "better safe than sorry" camp.

While I know of people who *say* they have put the 114.3 and 115 and been fine (read: anecdotal data) I have also *seen* a car with 114.3 wheels on 115 hubs (as a matter of fact I'm pretty sure it was an 8th Gen Imp) cause the studs to snap off. While 0.7mm does not seem like a lot, the hardened studs aren't really made to flex. And, if I'm not mistaken, most shops won't even install 114.3 on 115 or vice versa, or they make you sign a waiver. I could be wrong about the shops though.

Here's some previous discussion on other forums you may find helpful.

I will have to be on the opposite side of this, I know plenty of W body guys who run 5x114.3. While I have heard the whole breaking studs thing in all my years I've never actually seen proof of it happening more hear say type of thing. I mean if its a higher HP car you're going to bring to the track I could see it being a weak point but just for a daily driver I would't worry.

7/10th's of 1mm.

0.0393700787 inch = 1 mm

For ease of math, let's round to .040th's of an inch = 1mm.

.70 x .040 = .028 of an inch.

Meaning, each lug is being pulled inward .014 (14 thousandths) of a inch. A hair thicker than 3 sheets of paper.

Doesn't sound like much..

114.3mm = 4.5 inches, so it sounds like it's (or was) based on the english non metric system.

I personally doubt it makes a signficant difference from a strength/safety perspective. A tire store would naturally discourage it, for any potential liability concerns.
