I'll be doing a fair amount of driving in the snow on ski trips this winter and wish to have my winter tires placed on the 19" Tesla wheels that my 70D came with. Later in the year I'm likely to take the car home to Hawaii, and so two sets of wheels doesn't really make sense for me. I have two questions: 1) Have you ever had your wheels damaged while tires have been swapped? I'm trying to get a feel for the risk here. 2) Are the sensors for tire pressure part of the wheels and for this reason will they work with the new set of tires? Thanks!
