I don't put the tires in my car. I went back and get them with a truck. I don't risk damaging the interior.A question for those who are doing a tire/wheel swap with 21" tires. Do the extra tires/wheels fit in the car? Maybe I am doing it wrong, but the 20" tires are a tight fit even with the seats down. Not sure how I would get 21" tires/wheels back and forth to the shop (assuming I wanted the shop to do it).
