lifted ford trucks

When a tire says “38 x 15.50,” it means that the tire is 38” high and the tread is 15.5” wide. Sometimes you will see a 315/75/R16 tire size. The first number is the width of the tire in millimeters, the second number is the percentage of width in relation to the tire height, and the last number is the wheel size. In the example above, the tire is 315 wide, it is 75% tall as it is wide, and it can fit 16” rims.
