$60–$90 CAD per tire for decent used all-season tires with good tread remaining.  
$180–$500 CAD for a set of 4, depending on brand, age, and tread depth.  
Premium brands like Michelin often sell used for $75–$125+ per tire when tread is 70–90% remaining.  
For a quick valuation:
80–90% tread: $80–$120 each
60–70% tread: $50–$80 each
Under 50% tread: $20–$50 each
