Jamis Auroras are nice bikes. You'll need tires and tubes. Tires are personal preference and what fits in your budget. I like Serfas Seca tires. The foldable version is about $60 each. The non-foldable version is about $25-$30 each.

I also like Hutchinson tires. I had one bad experience with Michelin Race Pro tires (sidewall split while riding), but that was just one bad tire; alot of people like those tires.

I'm sure alot of folks will chime in with their preferences.
