which is what I did on Sunday on the Trans-Canada highway (car speed limit at 110 km. which is legal in Alberta) when returning to Calgary.

I didn't know it! We found out 3 hrs. later, after I got home that my front tire was flat...from a fine steel wire debris..strewn from exploded rethreaded truck tires.

The blasted truck tire debris on highways!! Shooting down a hill, you really don't want to run over those buggers.
