Ok. Here we go. So, this is what I'm trying to figure out on my own, but not coming to anything conclusive.

What I'm planning to run a new summer tire (probably 245/40/17) and get an alignment for that, but I want the alignment to be good for my winter wheels as well, which are 225/45/17.

What kind of camber should I put on the summers to get the winters to be as close to zero as possible? What are the height differences between the two tires? I know that width affects height as well, but I don't know it.

Thanks guys.

(ex. summer_ f -.5/r -.3 = winter_ f -.1/r -.0)

 

I've always thought that different tire sizes don't affect your alignment numbers since the hub is at a specific angle regardless of which wheel/tire you put on.

I think -0.5 is a good setting for summer/winter, although I consider that a bit conservative. I run -2.0 front and -1.5 rear.

 

I was told tires don't affect alignment

 

I run -1.5f and -1.0r, 0 toe, all year around. No problems. Tires wear the same and car feels about the same with a/s or summer only tires. I just recently got 18's and will most likely keep the same alignment settings.

 

The equipment you run will make a difference due to fitment, rubbing, etc.
If you don't run a spacer, a bbk and your car isn't too low, you can keep camber closer to 0. Now I don't know why you would want to do that, but to each his own.
You might want to consider a set of adjustable camber plates if you're willing to sacrafice a little toe for camber, again, to each his own.
