Correct, sorry bad choice of words. I was not thinking the tire and rim size but the space located in the floor for the spare. True it is only keeping a tire in the back.
Peace of mind I have AAA with a 100 miles of towing. This gives me the peace of mind if a tire blows out and the repair kit can not fix it or if I run out of charge unexpectedly (I have had my teanager borrow the car and leve me with 10%), or any other problem.
The Seattle also piloted 4 EV charge trucks that will come out and give you enough charge to the next charging station.
