So I said I'd update on the Minits Lite tires when I flatted. Well, after three weeks of commuting (12 miles a day, 5 days a week) I did manage to flat the rear tire on a small glass chip last night. No biggie, I pulled over, popped the chip out of the tire, put in a new tube and pumped it up and got home. The too-big 451 tube showed no signs of strain or wear related to being crammed into the 406 tire, and the new 451 tube I stuck in there was installable roadside as easily as it was in the pristine confines of my shop.

I would say that the flat I got is more typical of what I might expect to get on my road bike with its thin lightweight tires. A tougher tire probably would not have flatted on this glass chip and a rim strip would have prevented the flat altogether. If it happens again in the next couple of weeks I might consider putting a strip in, but altogether i still really like these tires. Urban warriors should look elsewhere, though.
