Recommended Stud Application & Quantity per Boot/Tire
* For these applications, calculate the approximate quantity needed per tire by multiplying the tire height (in inches) by the tire width by 3.14, and then divide by 11. Example: If the tire height is 60in, and its width is 15in, calculate as follows: [60 x 15 x 3.14] ÷  = 257. This tire needs approximately 250 studs.
** Varies depending on lug pattern and depth.
