Hi
I have 2024 GLB35 with 21" wheels and I'm thinking to purchase another set of wheels with 19" all season tires for coming winter season.
When I have another set of wheels, is it easy to program TPMS sensors every time I switch tires between 21" and 19" in fall and spring other than bringing in the car to the shop?
OEM: wheels: 21"x8.5, tires: SportContact6 255/35 R21
another set: wheels: 19"x8, tires: some M+S tires 235/50 R19
Speedo error is -0.79% according to the calculator.

As long as TPMS is programmed for MB/GLB, car picks up the tire pressure automatically from the sensors. Usually it takes a while as I carry the replaced tires in the car. Similarly the car corrected the tire pressure by location automatically after a while when Costco replaced leaking front tire and rotated to the rear.

235/50 R19 is the std tire size for GLB35 as long as the offset matches.
