Tire Change in Oshawa, specifically
The changeover window in Oshawa is narrower than most people plan for. The rule that matters is seven degrees, not the first snowfall — below roughly that, all-season rubber stiffens and stops gripping properly, which is why the first cold rain causes as many incidents here as the first snow does. Around Oshawa that threshold usually arrives in late October. Waiting for snow means booking in the same week as the entire city, and it means driving the run-up to that week on tires that have already stopped working.
