This measurement affects road contact area, fuel efficiency, and snow evacuation capability. Wider tires like 235s generally offer increased grip on packed snow but may perform less optimally in deep powder compared to narrower winter tires.

Q2: What does 65 mean on a winter tire?

A2: The number "65" refers to the tire's aspect ratio, which is the height of the sidewall expressed as a percentage of the tire's width. In this case, with a 235mm width and 65% aspect ratio, the sidewall height is 152.75mm (235 × 0.65). A higher aspect ratio like 65 provides a taller sidewall, contributing to a smoother ride by better absorbing road imperfections—especially beneficial on winter roads with potholes and uneven surfaces.

Q3: Are winter tires worth it?

A3: Absolutely, winter tires are a worthwhile investment for anyone who drives in cold climates. Unlike all-season tires, winter tires are engineered with:

• Specialized rubber compounds that remain flexible below 7°C (45°F), maintaining grip in freezing temperatures
• Aggressive tread patterns designed to bite into snow and expel slush efficiently
• Thousands of sipes (tiny tread cuts) that increase edge count for superior ice traction
• Up to 50% shorter stopping distances on snow and ice compared to all-season tires

The enhanced control, braking performance, and overall safety they provide significantly reduce the risk of accidents during winter driving conditions.

Safety Note: According to Transport Canada and the Rubber Manufacturers Association, winter tires are proven to reduce collision rates by up to 38% in snowy and icy conditions. For maximum effectiveness, install winter tires in sets of four to ensure balanced handling and prevent oversteer or understeer.

Q4: When should customers put winter tires on?

A4: It's recommended to install winter tires when ambient temperatures consistently fall below 7°C (45°F), even if snow hasn't started yet. At this threshold, the rubber in all-season tires begins to harden, reducing traction. Ideal timing typically falls between late October and early November in most northern regions. Conversely, remove them around mid-to-late spring when temperatures consistently rise above 7°C to preserve tread life.

Proper seasonal changeover ensures optimal performance and longevity for both your winter and all-season tires.

Q5: Is it OK to drive on winter tires in the summer?

A5: Driving on winter tires during summer months is not recommended. Winter tires are constructed with a softer rubber compound designed to stay pliable in cold conditions. When exposed to warm pavement (above 7°C), this compound softens excessively, leading to:

• Accelerated tread wear – potentially reducing tire life by 30–50%
• Increased rolling resistance, which lowers fuel efficiency
• Reduced handling precision and longer braking distances on dry roads
• Higher risk of hydroplaning due to compromised tread stability

For example, a winter tire sized 235/65R17 performs exceptionally well in cold, snowy, and icy conditions but sacrifices durability and performance when used outside its intended temperature range. Always switch back to all-season or summer tires when winter ends.

Expert Tip: Consider investing in a dedicated set of wheels for your winter tires. Mounting them on separate rims makes seasonal swaps faster, easier, and more cost-effective over time—plus, it reduces wear on your original wheels and extends tire life.
