Why carry a spare tire?

[DelawareH2]

I just picked up my H2 last night. My business partner bought his last week and after one hour of driving his, I had to have one.

I had a spare tire carrier mounted on the back, to free up room inside. However, I got the compressor with the H2, so I am wondering if I need a spare at all for around town driving. I can't remember the last time I had sidewall damage to a tire.

With the compressor and a tire repair kit, I don't see why I would need a spare. Maybe I'm too used to being on a motorcyle in the middle of nowhere, having to repair a punctured inner tube.
