Just curious, what wheels are you getting? would like to see and know what your winter wheel and tire setup will be

Tires

I haven't picked the wheels yet, but I already have a nice set of Hankook Winter i*cept evo tires that are great to drive in these Michigan winters.

Just make sure you get it rust proofed before you venture out to those salty ass roads.

 

[krzemien]

Same as G8 helps a little, can anyone confirm the actual pattern?

 

[jat63]

their is more than the pattern, (120 mm) you also have the offset, and centre hub diameter, most stores will have the info you need, this platform has been in the US since 2008.

it should be the same as VF Commodore which has a PCD = 5x120, centre bore=66.9 and offset=45

In saying that, looking at G8 it was slightly different according to this site PCD Pontiac G8 (2008 - 2009) 5x120 wheels | PCD, Offset, Center Bore, mounting and tire size data

Yes, I am getting some different numbers based on the sites I visit also.

However, I already have a set of wheels from a 2010 LaCrosse, and from what I can tell the bolt pattern is the same, the offset range is similar and the center bores are very close (the wheels might be 0.5 mm larger) so I might be good.

Idiot! ^^^^^. Sorry I had too.

Anyhow I would still like to know how much room the SS has for an aftermarket wheel. 40+ at least. Though I wish for a +35 or better but I doubt it. Anyone Aussie here know what people are using for aftermarket wheels?

 

[Whiskuz]

Anyone know how wide we can go in the rear????

 

[Headrat]

You are going to need all you can get under it !! LOL

 

[jat63]

Any wider you will need to roll the fenders if you lower the car

 

[Ctsv4now]

Does this mean that the CTS-V graphite black wheels will fit?

 

[roman1978]

yes yes yes and yes

 

[KenzSS]

Welcome Ctsv4now! So what's the plan with the wheels? :huh:
