Pushing rims out past the fenderlip increases your track and sometimes stress on the wheel bearings

Hate trying to explain offset without a picture.

I added one to the first post in the thread.

why dont you recommend adapters? i got some for my 01 camaro a while back so im thinking on getting the adapters so i can actually find a good rim (im majorly picky)

Hey guys,
After a lot fo hassles and more help from this forum than I got from my Stealership, I finally have 16" steel rims and Goodyear Nordic Studded winter tires for my 06 SS 2.4l.
The Stealership where I bought it never could tell me what steel rim to go with. If it wasn't for the info provided in this section, I would have had nothing to go on. Eventually, I found a dealership 3 hours away that sold me steel wheels.
After so many run-arounds with the stealership, I wasn't feeling too confident about fitment so I had them test fitted before I bought the tires. It worked!
The GM part numbers from the steel wheels are 9595769. This is a 7" wide rim.
I did not need new lug nuts. I guess the offset was enough to avoid it.
For the wheels, I bought 205/55/16 Goodyear Nordics (studded).
Tire price at Canadian Tire for tires, stem, balancing, install, studding and taxes (14%) came to $565.00 plus almost $300 for the wheels.
These are a new tire from Goodyear so it will interesting to see how they perform. I've used studded tires on all my vehicles. I've driven sporty cars all through our harshest winters and there is something just innately gratifying about passing a 4x4 on slippery roads, as they struggle on all-season tires. :-)

Special thanks to Erod and Raff for their very useful posts and updating this section.

Here is another site:

http://www.dakota-truck.net/TIRECALC/tirecalc.html

This will let you input most tire sizes to bring up a chart showing difference in tire height for different profiles (20 to 95) ranging from a tire size of 12 to 25 inches. You can then hit compare, under full analysis, to get difference in circumference as well as speedometer/odometer error. You can also calculate rpm and effective gear ratio changes. Hope this is useful.

More info for you, the stock LS rims off the "sport" model (16" ones) are 16x6.5". Oh, and you can wedge 225 width tires on them if your tire guy knows what he's doing

Does anyone have any hard data on the 07 Cobalt bolt patterns? I just looked at 3 '07 Cobalt LT's. 2 had 5x110 16" hubcaps/steel wheels and one had 4x100 15" aluminum wheels.

got a question, well the other night i busted a tire and had to get a new one. well the only size they had that would fit my car was 225/40/18. I couldnt wait for a day or two so i just grabbed it. first post says our rims are 18x7 but the 225/40/18 will only fit on a 7.5-9" wide rim. can anybody explain this and also can i go up to a 235 or 245 series tire on the stock rim and be fine with it and the clearance.

I don't, but a SS/SC 18" with tire weighs 52-55 lbs. I don't remember which it was before I worked at Gravana and was just helping out on the widebody project.

Erod edit: Wheel spacer/adapter info:



either get them drilled, get new hubs, or get a wheel spacer/adapter (http://www.skulte.com/info_pages.php/pages_id/3)
