Measuring tire rim size is a crucial step when replacing or upgrading tires on a vehicle. The rim size determines the diameter and width of the tire that can be mounted, and it is essential to ensure proper fitment and performance.
Tire rim size is typically denoted by two numbers separated by a letter. The first number represents the diameter of the rim in inches, while the second number represents the width of the rim in inches. For example, a rim size of 15×7 indicates a 15-inch diameter and a 7-inch width.
