You can see the size of your current tires by looking at the tires currently on your car. You will need to know your width (eg. 190), profile (eg. 60) and rim (eg. R16). Refer to the GIF for guidance.
We strongly recommend that you go and take a quick look at your current tires before ordering. However, if you know your make/model/series use this widget to find out the matching tire sizes.
