It is possible to change the wheel and tire sizes, but a general rule of thumb is to keep the total diameter of the wheel and tire the same. So, that means that downsizing an 18-inch wheel to a 17-inch wheel would include a proportionate upsizing of the tire sidewall to compensate.

Can I use 18 inch rims instead of 19?
Despite what your car salesperson may have told you, it’s OK to get an 18-inch spare to go with your 19-inch wheels.
Does rim size matter for tire size?
Tires are a part of the wheel setup. For instance, your vehicle has a set size of rims, but you can buy different sizes of tires to fit those rims, as long as the middle of the tires is the correct size. That being said, a vehicle with bigger rims will often be able to fit larger tires than other vehicles.
