Z_S1500

Hello, I m waiting for our 2022 Silverado High Country. As I m in Canada, the truck will come standard with 20 inch wheels and for winter I m thinking about getting 17 inch wheels. Size for the winter tires would normally be 275/60R20 vs 265/70R17 I m thinking about getting. Bolt pattern would be the same. Now I m wondering and would like to have your advice please: normally 17 inch wheels are proposed for lower end 1500s but not mid and higher range ones, may I run into trouble in any way? Perhaps calbers and discs on High Country and LT models are not of the same size? Or will I be just fine if I install 17 inch wheels? Many thanks
