Q&A for How to Measure Tires

If you are referring to a 1965 Renault 16 De Luxe, here are the measurements: Standard tire size: 145 - 355; tire width (mm): 145. Tire sidewall factor: 90. Rim size (in): 14. Total wheel diameter (mm / in): 617 / 24.3.

Most truck tire sizes are indistinguishable from car, SUV, or CUV tire sizes. The basic format is equivalent: Section width (in millimeters) “225,” aspect ratio of sidewall “45,” then tire and wheel diameter “17.”new cars information.

The number 175 in a tire size (e.g. 175/55R16) is the width of the tread of the tire in millimeters (mm). A tire which has a size of 205 as the first number is 205mm wide and wider than the 175mm tire. The second number (55 in this example) is the value of the height of the sidewall of the tire. It is represented as a ratio of the tire width and referred to as series. For the 175mm width tire a 55 series tire is higher than a 45 series tire. The last number represents the rim size of the tire. It is measured in inches. In this example it is a 16 inch rim. So, for a tire size of 175/55R16, this tire is 175mm wide, has a 55 series sidewall height and mounts to a 16 inch rim.

4.10 = refers to the width of the tire, measured in inches. 3.50 = refers to the distance from the outside edge of the tire to the outside edge of the rim.

The first number is your overall diameter of the tire. In this example the tire diameter or "height" is 33 inches tall. The second number represents the width of the tire.
