hey guys. i'm sure this may have already been beaten to death but i was wondering what size for wheels and tires are best. i need to get winters on soon and i wanted to go with 16" steelies. whats the bolt pattern too?
thank you

 

Correct me if I am wrong but I believe its

18x7.5
5x110
+42

As for rim fitment, I cant help you there.

 

215-50-16 looks real good for snow tire. check out this thread I thing it looks good for snow tires.

If you have an HHR SS, 215/60r/16s with 16' steelies are on mine and are fine. As long as you have OEM brakes. If you have Brembos maybe not.

 

For winter I did the 215-50-16 as the Goodyear I put on was with in 2 Revs per Mile of the factory Pilot 18 inch. It keeps everything reading accuratly.
