The hub centre hole diameter is 65.1 mm

 

These wheels came off of a 2006 Saab 9-3. Fit perfectly, no issues. Whether they look right on a HHR is your opinion. I'm kinda mixed on the look.

 

Not surprising, they were built on the same assembly line.

 

Yup, that’s why it’s always good to do research like looking on this forum. Otherwise I would have passed over these while hoping HHR or Cobalt wheels would pop up at a good price. Can’t beat a nice set of wheels for $100 the set. Cool thing is I had the steeliest with the circles and hubcaps, I did a quick sand down, primed and semi gloss paint and I bet I can sell them for more than I paid for these.

 

Cobalt 18 “ alloy wheels from the SS fit
and the 17 “ alloy rims also

 

I guess people know about the Cobalt wheels so they’re not cheap - even the steelies are listed on CL for $150. Saabs are like the bald-headed, pregnant stepchild - nobody loves them. I actually saw a set of 17” Saabs for $120 but two of my tires were still good and I didn’t want to buy a full set of tires. Fortunately the guy who had these just wanted to get rid of the car and the wheels. Funny because I think Saabs are cool cars.

I stumbled on this site when I was looking for ideas, lots of good listings, at least for information, even if you buy elsewhere
it's where I found a couple Jeep rims I like that would fit... but I'm not sure how they'd look

It’s a matter of taste, whatever you like on your HHR!

 

A little late to the party, but if you are looking to see if you can "Upsize" or "Plus size" your tire and rim combination, this tool might help.
