If its a temporary spare then I hope the allowed range on that tire is good enough for long distance commutes at regular highway speeds because I will be taking this on road trips. If not it will be more of a reason for me to just rent a Suburban.
Smart move, just knowing that in 20 minutes you can be back on the road sells me enough on keeping the spare. I hate depending on roadside when its something I can easily do. Only in the city can I see myself without a spare. Roadside reponse times are greater then.I take my Outback on huge trips into the mountains. I've had flats and will never go without a full-size spare again.
