Is 5x4.5 the same bolt pattern as 5x115.5?
No, 5x4.5 and 5x115.5 are not the same bolt patterns. The first number indicates the number of lug nuts or bolts that secure the wheel to the hub, and the second number indicates the diameter of the circle on which the lug nuts or bolts are located, measured in millimeters. So, a 5x4.5 bolt pattern means that there are five lug nuts or bolts arranged in a circular pattern with a diameter of 4.5 inches, while a 5x115.5 bolt pattern means that there are five lug nuts or bolts arranged in a circular pattern with a diameter of 115.5 millimeters. These are two different bolt patterns and are not interchangeable.
