16x7 i believe.

the 8 spokes are 16x6.5 and the 12 spokes are 16x7
all run 225/60/16 tires and have +32 offset i believe
to me the 12 spokes are "stock" since they are the rims specifically for the riv, while the 8 spoke design was offered on other buicks as well. the base wheels are ugly mono wheels with lots of little spokes around the edge, but those were only put on 95/96's with no s/c or other options.

Sorry, I don't know too much about rims other than size and tire width so would these rims work on a '96 Riv?

Pretty damn cheap for four custom rims with tires. I was actually thinking of going with black wheels on my Riv and these are pretty cheap and almost exactly like the kind of rim I would've bought if I bought them new. Really need a kinda quick response because if they will work I want to message him ASAP.

Dude...you don't want those....theres a penny sticking out of them....

..I'm pretty sure our bolt pattern is 5x115

With an adaptor, but not with the stock bolt pattern:

BTW, you could have found this info through the sticky in the suspension and handling section and got it faster.

Well, I looked on a custom wheel site and they show some rims that are 17" that have a 5 x 100 bolt pattern and I told it I have a '96 Riviera. There were also some 5 x 110 as well as 5 x 115 and some actually said stuff like 5 x 115/110. Here is the said page.

Ah okay. So the tires he has and everything will work I just need the adapter? Where could I find said adapter and for how much? Also, I've heard that adapters will screw up your alignment and your car won't hold an alignment if you use them. Any truth to that?

Follow the link I made, the info is there.

I know nothing about the alignment problem.

I see them, but it's not really clear on what I'd need to buy or anything. I'm sure that's like $50 for each one which is gonna make these wheels $450 total. Screw that, I'm not spending that much. I guess I'll just wait until I'm filthy rich enough to buy them (In other words, I'll probably have a new car by that time...). I don't see how you people blow all this money on stupid ass wheels like it's nothing. Spending $1,000+ for wheels is an outrage to me and I'm not that stupid.

Thanks for the help guys, helped me determine I'm never putting custom rims on this car. I still might buy the rims from a newer Buick and use those. Big ass rims just add more weight to your car which will slow it down and I certainly don't want that.

I don't have big rims (yet), and I certainly wouldn't use spacers if I did. I don't think it's stupid to spend that money if you can afford too. Most everything enjoyable in life is stupid and better not done if you think about it. But if you strip it all out you won't have much to live for. Then you'll get heart disease and die young. And no one will like you because you'll be boring.

These rims didn't work out for you, but it doesn't mean there aren't others out there that will. Research is your friend.

Cause his rims wore out and wouldn't hold air no more In case you're wondering.

I'm saying, if I am gonna spend money on my car I'd rather it go under the hood or towards an entirely new paint job. I just can't fathom how anyone spends such amounts of money on cars. Even so, I'm probably just dreaming I probably won't do anything to my car except maybe buy my missing center caps. I don't even feel like it's worth it, I have a '96 which is apparently almost as weird as a '95. If I had a '97 or newer I'd be set, good transmission, better rotors, less work altogether and a better car.

But I don't. This is why I'd almost just like to find a GTP or PAU. But then I'm right back to my car is worthless to everyone else and their car's worth a lot. Jeez, I'd be happy to get a '97 GTP or PAU with like the same miles as my car. Never happen, I'll be stuck with my car until it just blows up. Then it'll really be worth nothing, but I suppose then I have justification for buying another car.
