You are not really supposed to deviate from the factory tire height and/or rolling diameter. A lot of things are related to the mechanical design are directly connected to that oem tire size. Speed sensors, transmission related components, traction control related items, literally a laundry list of stuff would be thrown off caliber. I'm almost certain that with AWD it's even more of an issue. You ever notice the warnings about replacing only one or two tires on an AWD vehicle? That's why. Just the difference in tire tread depth can make things a little goofy.

I wouldn't go as far to say that it will tear up any components as long as the difference isn't too drastic but it definitely will cause a few sensors or such to be off.

That's why when you increase the wheel diameter you offset it with smaller profile/sidewall tires.

If someone wanted a larger sidewall to add more comfort they should be looking at going smaller on wheel/rim size first to compensate for the larger than OEM profile/sidewall tire.

There are websites where you can play with the sizing to get it right.
