These Cosmis XT - 206R wheels are easy to use. Just make sure to double - check that they fit your vehicle before you buy them. When installing, you might need to make a few small adjustments. Once they're on, you're good to go. To keep them looking great, clean them regularly with a mild soap and water solution. Avoid using harsh chemicals as they can damage the black finish and the machined lip. Also, check the wheel nuts periodically to make sure they're tight. If you notice any signs of wear or damage, have them inspected by a professional.
