Tks for the input all.
Re: Inspecting the tires at the end of the ride... It ain't happening.
If I take an hour or more for the morning commute, as I commonly do, plus stop in 45 minutes at the gym to work out, as I now do, I have to hit the ground running when I get to school, literally every minute counts, some days worse'n others.
Here's my bike early one morning back in July tied to the back railing of the Cambeltown to Ballycastle ferry such as it was (no worries, never mind that blue Scottish sky, Irish rain washed the salt right off

)
The front tire is easy to see despite the fender, the back tire not so much, plus I always have panniers on. Surrounded on arrival by a group of kids needing my attention about various minor matters as I generally am, a careful inspection of the tread on the back tire each day is not likely to happen. Departure ain't all that much different, and I'm on the run all day.
I'm just gonna factor in the price of a premium tire once or twice a year as the cost of doing business.
Speaking of premium tires, how come nobody says much any more about Armadillos? I recall 15-20 years back they were the bomb when it came to tough, though hard as a rock to ride. I had forgotten all about them.
