If you use larger diameter tires than the factory size, you are basically changing the gear ratio of the vehicle. Larger tires will give you a higher ratio than what might be optimal for you drivetrain and weight.
It will also mess with your speedometer accuracy. With larger tires, the speedometer will read slower than you are actually going.
On the other hand, smaller tires will have the exact opposite effect.
If you have to buy tires anyway, I'd highly recommend you stick with what the door sticker calls for.
Don't run different sizes of tires on the same vehicle, you're just making things more complicated if you have issues while out on the road.
