Yes, you can.
Yes, you can replace 215/55-R16 tires with 205/50-R16 tires, but there are important considerations. The 205/50-R16 tires will have a smaller overall diameter, which may affect your vehicle's speedometer accuracy and handling. Additionally, ensure that there is enough clearance in your wheel wells to accommodate the change in width and aspect ratio. It's best to consult with a tire professional to ensure compatibility with your vehicle.
