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
