Can you replace 205 70R15 tires with 215 70R15 tires?

Yes, you can replace 205/70R15 tires with 215/70R15 tires as long as the new tires fit within the recommended specifications for your vehicle. The first number (205 or 215) represents the width of the tire in millimeters, so the 215 tires will be slightly wider. The second number (70) represents the aspect ratio, which is the height of the tire sidewall as a percentage of the width. The last number (15) indicates the diameter of the wheel in inches, which should remain the same for both tire sizes.
