What is the height of the front tires (you didn't list what the profile was)? Max is 26.2" tall.
If the front and rear tires are different sizes you will mess up the ABS pretty good.
And most tire shops recommend you do not exceed 3% (at least 3% comes to mind) difference in height between old and new tires.

Using the tire size calculator at https://tiresize.com/comparison/ -
- the 235/70-16's are 29" tall
- the 225/70-16's are 28.4"tall

If your car has ABS and/or ESC different sized tires on different axles will make the car undrivable.

Your profile shows you have a SS.
Why would you even consider the sizes you mentioned above ? Stick with the size it came with or something close if you're going with different rims.

That looks like a difference in height to me. Actually it is the circumference that matters, but since Pi are square....

The 70 means the sidewall is 70% of the width, therefore width does matter.

Kenny, you need to read and understand the advice here, and realize you need to give up the idea of different sized tires front and rear.
The HHR is not a 1970's car. If you want to run different sized tires, go grab yourself a Nova or such.

Am I missing something here ?
Is this not an SS we're talking about ?
Once again, why would you want to put on way skinnier tires than the car was designed for ?
