Winter Tires for 225/55R18

https://www.willtheyfit.com Wheel spec for your vehicle you should be able to find on the wheels you own stamped on the back, in the manual, or via some googling.

Tire wise that is a standard size down and your speedo will only be off by ~1%. Usually anything under 3% is good to go.

These are the correct sizes for your car for winter tires. you can choose 16" or 17", taken from SimplyTires website - http://simplytire.com/winter/buickpdf.pdf

215-65-16
215-60-17

i would go with 16" as its cheaper.
