For example, the brand and size. Is there any place for me to check what the original tires which come with the car are? I live in Canada and whenever I search it on Google the links lead to goodyear.ca where I can search for available tires.
All cars have a tire information sticker somewhere in the driver door jam. The sticker will list the tire size and speed rating. The exact brand is not important and can't be easily traced either. I worked at a dealership for a few years and it was not uncommon for a single model of cars to come with three different tires on it. Choose the tire based on the driving that you do and the conditions that the tire will see.
