I was just wondering the answer to this question. Thanks! This is great news. It's nice to not have to call for roadside assistance and be self sufficient. To my shock, my wife's Volvo s60 doesn't even have any kind of spare! Yes we had to get it towed and rode in the tow truck. Luckily it was before we had kids.
The national product manager Dominick Infante said it is a full size spare (7:05).
