Quick Question, I am about to pull the trigger on my order but want to run a thought by the group. I am planning on ordering a S85 with Air Suspension and 19" wheels. After delivery I then plan on finding a set of new/gently used 21" Tesla rims and want to use those on my car and keep one 19" wheel as a spare and sell the rest. Is a trip to the SC required to change the air suspension setting from 19" wheels to the 21"? Do you foresee any problems going this way? My thoughts are that buying the 21" gently used and then selling three of the four 19" wheels will leave me with a spare wheel that I can throw in the frunk for any long road trips all while saving me about $2,000 after the income from selling the three wheels. Thoughts?
