As long as you have enough clearance, meaning the tires don't come to contact with body panels, etc, you should be fine. No need to change.
The only thing the size change will affect is your odometer and speedometer reading.
To find out exactly how much it would change use this website: https://tiresize.com/speedometer-calibration/
It has a calculator where you can put your model/make and tire sizes.
If you want to calibrate the speed to match your tire size, there are after market devices that let you do that. But these are not easy to install. You have to tap the wire of the speed sensor. Here is one example of such a device.
If you are concerned about speeding tickets, use a GPS. GPS speed is almost as accurate if not better than your speedometer.
EDIT: One more thing to keep in mind is that, if you car is AWD, then you have to be very careful about having different size tires in front and back. This can create premature wear on your AWD system. This does not apply to OP's car I believe.
