i need to know what the bolt pattern is, to see if my winter rims from my 2005cobalt ss will fit or do i need new rims ?????

 

5x110

 

Yes chances are if they fit your cobalt ss then they will fit the HHR. The factory wheels are the same specs anyways. 5x110, 42mm offset.

 

I purchased a set of steel wheels from a Cobalt SS already mounted with winter rubber off of Craigslist and they've worked like a charm for 2 winters now.

I just recently decided to do the same for my wife's Cobalt 2LT and luckily did some research beforehand to find out the Cobalt 2LT uses a 4-bolt pattern.

 

That's a curve ball for sure, 4 bolt..
