Ok. General consensus is that it's better if I replace it, so I'm going to buy a new one. I'm a bit tired of replacing perfectly good tires after a few months... unfortunately my commute involves some roads that seem to have too much debris, or where due to stopped traffic I'm forced to ride on shoulders that aren't as clean as I would like, and tires don't last me more than 9 months. I never managed to replace a worn tire on the road bike since I started commuting with it. And on the old bike I managed to puncture a rim with a nail (never seen that before, and hope that it doesn't happen on my current bike with much more expensive rims). Now you see why I'm so willing to keep the tire rolling...

Yes. Note that I'm talking KPH not MPH. I can ride on the "flats", but I usually prefer to commute using the hilly route that involves some twisty roads, and some fast and steep descents. It's a lot more fun, and after the initial climb it's fast in a addictng way. I don't always reach 70 as it requires quite a bit of pedalling effort on my route, but 65 is a pretty usual top speed on my commute rides.
