I would support a yearly inspection as part of renewing your rego where cars could be deemed "un-road worthy" if the tires are bald however.

Nope

In 2005, there were 12,539 personal-injury collisions. In 2008, there were just 6,033. I’ll bet those 6,506 German drivers who didn’t crash would be happy to endorse how effective winter tires can be in keeping drivers out of emergency rooms.

Even Quebec, which already had 96 per cent of drivers using winter tires before they became mandatory in 2008, showed a 5-per-cent drop in collision injuries that year.
