To find out what tires fit your car, you will need to know the make, model, and year of your car, as well as the size of your current tires. You can usually find this information on the sidewall of your current tires, or in your vehicle owner's manual. Once you have this information, you can visit a tire retailer or car dealership and they will be able to recommend the right tires for your car. Alternatively, you can search online using your car's make, model, and year, along with the tire size, to find a wide range of options.
