Question about Wheel Size

[GotMyG8V8]

So I might have an incredible deal possibility of getting snow tires and wheels for around 425 used from someone locally. The tires are Dunlop 235/55/17 Wintersport SP and the wheels look like they're right off the Bonneville SSEi that the guy was driving. I know it's hard to see, but I'm hoping these wheels will make clearance, if anyone has any insight or can just give me a little reassurance i'd love it! Thanks guys

Need bolt pattern and offset. Can they send a close up picture of the inside of the wheel where the information is stamped on it?

I'm waiting for a call back from the guy, when he calls i'll get that information. Thanks!

Edit: Guy is going to take a picture after work and send it and i will upload it as soon as i get it.

Here is the picture. Looks to be 17x7.5 and a 51 offset. Let me know please!!!! Thanks so much for the help, this will save me so much money and allow me to get them now.

They are 1/2" more narrow than stock rims but I think they should work. My only concern would be the brake caliper clearance since they are 17" rims. What kind of caliper clearance do you have currently? Do you think there is .75" of room to spare?

Here are pictures from each side, i took them just a couple of minutes ago, i have the 19's, so it would otherwise seem like i have plenty of room. Thanks again for all the help.

Bad news :( I just checked on the Bonneville lug pattern is 5-115 and the G8s are 5-120.

of course it has to be off ever so slightly. Damn

I have a question...205 50 17's. I'm assuming they won't work but I'm just wondering. I found a set of bmw wheels with winter rubber on em :) But i have a feeling they won't work either.

The bolt pattern is right on and the wheels look like they'd have enough clearance. I'll post a pic
