Rules of the Road
For best traction during the Ontario winter season, it is recommended that a vehicle be equipped with:
Show Answer & Explanation
Correct Answer: A. Four winter or all-weather tires with the same tread pattern
Four matching winter tires provide balanced grip front and rear. Mixing tires (two winter + two summer) creates uneven handling that can cause spins on slippery roads. Tires must also be clearly marked with the mountain/snowflake symbol or the M+S designation.
Why the other answers are wrong
- B.Two winter tires on the drive axle onlyTwo-tire installations cause dangerous handling imbalance; all four positions must match.
- C.Studded tires in all four positionsStudded tires are permitted only in specific northern municipalities and only in certain months; they are not universally recommended.
- D.All-season tires rotated every 6 monthsAll-season tires rotated do not provide winter-grade grip; dedicated winter or all-weather tires are recommended.
