I have an extra set of stock steel rims from my wife's cobalt SS. I would like to paint them gloss black and mount a wide white wall tire for a retro look. I want to add Pedder's lowering springs too. Would this work? Would a 215/60/16 tire work best or a 215/65? Is there a center-moon/bullet option that would mount to these wheels to cover the hub? Any suggestions would be appreciated!

 

Here's a wheel size comparator, plug in the SS tire size & then the other size you want, it will show you exactly the diff & even the speed-O diff, if you scroll down a bit..

Thanks sleeper! That helps. Now with the SS already being lower than the other models and adding the Pedders drop, can I fit the 215/60/16 (2" whitewall) without tearing up the wheel wells? I'm also not sure on the backspace for the cobalt steel wheels or the HHR SS wheels for an exact input on the calculator. Sorry still new to the HHR game.

 

Ok... I have been searching and have found that the stock wheels from the cobalt (assuming they are the same as the HHR) are 16x6.5 42 offset and the SS wheels are 18x7.5 38 offset, so looks like the stockers would fit with the 215/60/16 tire (wide WW). As for the drop and rubbing, not sure.
