I have 18in rims on my 2020 rs.Because 21in so expensive. I'm used g the 18 with contact 7 winter tires. Seems pretty good to me

Have you noticed if mileage and speedometer are off with the 18 inch wheels? I talked to GM dealer and he said there is no re-calibration program for the Blazer like there is for the trucks that want to go with bigger size wheels.
