Yes, you can use tires with the size 225/75R16 instead of 225/70R16, but there are considerations. The first number (225) is the tire width in millimeters. The second number (70 or 75) is the aspect ratio, indicating the height is 70% or 75% of the tire's width. A higher aspect ratio means a taller tire. This substitution will lead to a slightly higher ride height and could affect speedometer accuracy and handling. Ensure your vehicle has sufficient clearance for the larger size.
