— Are tire sizes and tire noise linked?
The rolling noise of a tire is shaped by multiple factors. These include the tire’s size and profile, as well as how the tire is mounted on the wheel.
One key factor is the width of the profile. When the profile is wider, all else being equal, tires tend to generate more road noise.
For instance, moving from 195/65 R15 to 205/55 R16, and even more to 225/45 R17, should be considered with the expectation that wider tires may reduce quietness inside the cabin while improving grip in certain conditions.

Considerations for tire availability in popular sizes
Tyre choice and maintenance influence overall vehicle safety and performance. When tires are not available in common sizes, owners may face longer wait times for replacements, which can affect daily commuting and emergency responses. Tire selection should balance load capacity, speed rating, and climate suitability to ensure reliable performance in Canada and the United States.
Responsible organizations and fleets focus on ensuring a steady supply of tires for essential vehicles, including ambulances, emergency services, and humanitarian support teams. Proper tire allocation supports quicker response times, safer travel, and steadier operations in critical situations. Stakeholders can consider planned purchases and stock management to maintain readiness for diverse conditions and weather across North America.
