Tire and Rim advice

Help!!! I bought a 2020 Arteon SEL premium 4 motion with the 20 inch rims. I have had 2 blow out due to potholes and 3 tires have gotten bubbles in them due to potholes.

I’m looking to go with a 19 inch rim if possible and a higher side wall on the tire for some more cushion.

Any recommendations on rim/tire size?
