Is your vehicle running a single or dual wheel setup?
The size of your tire is a series of numbers on the tire just below the manufacturer's name. Examples include: 425/65r22.5 // 20.5-25 // 31x15.5x15
Count the number of bolt holes on the wheel.
Straight bolt holes = Hub Piloted. Tapered/Beveled bolt holes = Stud Piloted
IF STUD PILOTED: is the taper on the front side, back side, or both?
Measure across the center of a single bolt hole.
Measure from the center of the 12 o’clock bolt hole to the center of the 6 o’clock bolt hole OR from the bottom of the 12 o’clock bolt hole to the bottom of the 6 o’clock bolt hole. See Figure 2A.
Measure the distance across the center of the pilot. See Figure 2B.
Measure the distance from the inside of the disk to the very inside edge of the wheel. See Figure 3.
