Converting Metric to Inches
In that location are two ways that tire manufacturers display tire size, inches and metric. How to read tire size in inches is very direct forward. Instance A : 33X12.50R15 The first number is your overall diameter of the tire. In this example the tire bore or "height" is 33 inches tall. The second number represents the width of the tire. In most cases with inch measurement tires the width volition have a .50 decimal after the initial number. In example "A" this reads 12.50, significant the tire width is 12 and ane/2 inches. The concluding number simply is the bicycle size or "bore" of the wheel that the tire will fit on.
How to read tire size with a metric measurement is a trivial more difficult and usually takes a calculator to get exactly right.

Instance B : 285/75R16
On metric tires the kickoff number is your width of the tire in millimeters. In example "B" this reads 285mm. In that location are 25.four mm in one inch. To convert 285mm to inches yous divide 285 by 25.4 to get xi.22". And so the width of a 285mm tire is eleven.22". The adjacent number represents the percent of the width (285mm or xi.22") that is the sidewall height of the tire. In this instance the side wall superlative of the tire would exist 75% of 11.22" which is eight.41" or 214mm. To then get the overall bore of the tire you would add together the two sidewalls measurements and the diameter of the wheel. In example "B" the concluding number "xvi" is the bicycle size the tire volition fit on. Therefore the sidewall twice would be eight.41 x 2 = 16.82 plus the wheel "sixteen" makes the tire tiptop 16.82 + xvi = 32.82. And then a 285/75R16 metric tire would summate to an inch measurement tire of 32.82X11.22R16. Call back, not all tire sizes are manufactured in both metric and inch sizes and so learning how to read tire size can be a valuable tool for anyone in the market for new tires.
