Possible to install wheels with 5-120 bolt pattern?

[fungo45]

I'm enjoying my 2009 3.8, but am starting to think ahead to the upcoming Chicago winters. I've got a set of winter wheels from my 2009 Pontiac G8 sitting in my garage. Before I sell them, I was wondering if there is any way to fit them on the Genny with some sort of adapter or spacer.
The bolt pattern is 5-120 and I think they have a 40mm offset. Is there anything I can do with these?

I think this is what I am looking for - right?

Didn't realize that 114.3mm = 4.5 inch.

Do I need to worry about the center bore diameter of 73mm?

Yes,those should work. Regarding the 73mm hub, our genesis' have a 67.1mm bore so it should be do-able as long as your jumping it or taking it to the track . Although it is not ideal, it will work.

Those are way too bit. 1.25" is huge. You never stated what the wheel size was that you were trying to put on in the 1st place so nobody can quite answer you. When it comes to switching lug patters, you're better off selling the wheels you have and getting something that fits. Always avoid spacers if you can help it. You're just going to make the car run a lot sloppier and your steering is going to be noticeably heavier and less responsive.

This is wrong. He should be concerned. ALWAYS, without exception, run hubcentric setups. You can get hubcentric rings for this purpose.

Not once did i say he should use that non-hubcentric setup. If you read my post, I said "...Although it is not ideal, it will work." which is absolutely true. I have seen plenty of cars with non-hubcentric wheels. I am not endorsing or recommending running non-hubcentric, I am simply saying, it is not typically a major issue if it is not permanent....
also, these are not wheel spacers. they are adapters so its not just like a washer on the hub spacing out the wheel and putting extra stress on the studs, its basically makes its own studs.

+10. Trying to pound a square peg down a round hole is not wise. LoL

Don't do it.
First reason is fitment. If you are adding a 1.25" spacer then that is the same as lowering the offset of your wheels, so now your +40 offset wheels become +8 offset wheels, and based on width and tire size they may not fit, plus for winter you'd want a wheel setup that doesn't stick out too far so its easy to clean the snow out of your wheel wells.
Second reason is that its winter and corrosion is more common. Depending on where you live they may use salt and stuff like that in the winter, making things rust. Have you ever had a wheel not come off the hub easily? Basically siezed on, and you have to kick the wheel for it to pop off. Think about how to do that when its a spacer siezed to your hub, gonna be impossible because you have no leverage to get it off.
I've dealt with 25mm bolt on spacers in the summer and even that was a pain in the ass, I certainly wouldn't do it in winter.

"it's doable as long as you don't track the car or do any jumps"

Neither of these are relevant to why he shouldn't do it nor are they justifications for it. Also, whether it's permanent or not does not change anything either. Point blank, it should not be done because it my not fit, it may cause vibration, it ruins handling, and his wheels might fall off.

Thanks for all the responses. I had a feeling using the adapter would not be the best solution, though I was hoping it was just because it would make things cheaper and a lot easier.

I'll plan on looking for some cheaper 17" rims and just throw the existing tires on them. The tires that I have are 235/55-17, so not exactly stock (225/55-17), but the speedo difference is less than 1 MPH at 60. I can live with that.

While not an original idea, when needing snows for my 3.8, I bought a set of 17" rims from base model of Genesis off ebay. I don't think I paid more than $100 each inclusive of shipping and they were virtually new. Many switch out the stock rims with something custom in a larger diameter. Apparently, one wants a narrower tire for snow, so the higher the profile the better (and also cheaper). Therefore, a 17" snow is ideal.

Good luck on your hunt.

another option is sell those old wheels, with the money buy a new set of winter tires and mount it on your current summer rims. Next year, buy some new 19/20's for summer!
