Looks like the 235/45/18 are not a good choice as the diameter is off more than the 245/45/18 compared to the stock 225/50/18. Does this mean, even thought the 245 might feel pinched on the front, they will actually stabilize the car more and traction control won't kick in as often?

That's what I was referring to in my original post. If you go with 235's, you're going to be a little over 2% off. It will work, but you will trip your VDC more easily if you drive aggressively. Adding a 255 size in the rear at the same time returns it to very near stock diameter tolerances.
EDIT: I used a different tire calculator which yielded slightly different results.

I think you used 235/50/18 instead of 235/45/18 in your original calculations. Probably why you came out with different results. What I am trying to do is go 245/45/18 all around so I can rotate them. I understand you said to change the front rims if I want to do that but I am trying to see what the side effects would be if I keep them they way they are. I am not looking for a super sport performance. I just want it to be stable and safe with out having ill mechanical effects on the car. Thanks

Ahh, you're right, I was using a 50 profile in the front in my calcs.
If you just want to run the 245's all around, you certainly can, and lots of people do. Like I said, it pinches the tire a bit when fitted to a 7.5" rim, but it's no biggie and you may never even notice unless you're really getting into some serious corner carving. If you search around here a bit, you'll see it has been done lots and lots of times, and many folks are perfectly happy with it.
With the assumption that you'll be looking to eventually rotate the wheels (as a benefit of running a square setup), you'll need to remove the bolt that is inserted into the front hubs to prevent inadvertently mismatching the staggered wheels. It will be obvious when you see it.
Okay may be I should have been specific about my car here. Since this is a sub forum for the 2007-08 Sedan, I assumed the topics here would be for those models.
My car is a 2007 Sedan Journey with the performance tire and wheel package.
I am currently running 235/45/18 in the front and 245/45/18 in the back. vqsmile, most likely right about this. My traction has been very sensitive since I put the 235s on.
You know you can put your year/model in your signature, right? I saw the "2G35" in your username and thought you had a 2 door.
Anyway, good luck, sounds like you and vqsmile got this figured out.

Great. I am just going to rotate the tires, not the wheels. I imagine rotating the wheels with the tires would cause an issue. I have access to a shop I can use to dismount the tires and rotate them.

Whoa, hold up a second. Are you saying you want to dismount the front (225) tires and install them on the rear (8.5") wheels now? . . . or did you mean that, after you buy 2 more 245's for the front 7.5" wheels, when it does come time to rotate, that you would accomplish it by rotating all the (245) rubber only and not wheels?

Haha no after they are all 245/45/18, I will just rotate the tires and not the rims

Gotcha. That will certainly work, but it seems like it would still be easier to simply remove those little "so-you-don't-mix-up-your-fronts-and rears" bolts so you just rotate the entire wheel and tire, as usual.
