+1. If you're not plan on off-roading, I would purchase a tire with low rolling resistance as well. Recently I purchased Panaracer Pasela PT 35c- folding variety. They are fairly smooth, fairly high volume tires. They seem light, fast, supple, and really, really comfortable. Best of all they don't break the bank so you can afford an extra one to take with you.
