Hello all, I am in the process of ordering a 2020 XC40 Inscription with C Suspension and Polestar. I would like ideas of what is the best tire size for this vehicle. What is being offered is 18", 19" an 21". I have read every review possible, however, I have not found a review or information on the best tire size for this vehicle. Frustrated that this is not an area of review for most reviews. Thank you in advance for your opinions.
