Critical clearances, motorcycle compatibility and stability, load-bearing capacity, speed rating, radial vs. non-radial, pattern and tread compound requirements, inflation recommendations, and front-to-rear tire matching will all vary with tire selection. Proceed right to left. Multiply the ones digit of the bottom number to the next digit to the left in the top number. If you carried a digit, add it to the result and write the answer below the equals line. If you need to carry again, do so. multiplied by 100 to give you a whole number for the tire. So instead of .9 the tire is stamped 90.

the decimal would then be 0.05, and so on. Beyond this, converting fractions into decimals requires the operation of long division. In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction of 3 the numerator is 3, and the denominator is 8. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5

Sometimes a catalog will list a tire as TL, BL or RWL. These have nothing to do with the size or handling. They are strictly descriptive. They describe the look or another feature of the tire. Abbreviation TL is a descriptive abbreviation. {See the sections below for more info.} It indicates that the tire is meant for a tubeless application. The majority of modern motorcycles use tubeless tires. If your bike has wire spoke wheels you need to use a tire designed for use with a tube inside. All those spokes and nipples are not air tight. The Speed Rating is explained in detail here. For our example a speed rating of Z means this tire is rated for speeds exceeding 149mph.

Dirt bike tires are sold in both metric and inch sizing format but do not always have a speed rating. More often they are rated by terrain. Arrange the numbers one on top of the other and line up the place values in columns. The number with the most digits is usually placed on top as the multiplicand. Converting from decimals to fractions is straightforward. It does, however, require the understanding that each decimal place to the right of the decimal point represents a power of 10; the first decimal place being 10 1, the second 10 2, the third 10 3, and so on. Simply determine what power of 10 the decimal extends to, use that power of 10 as the denominator, enter each number to the right of the decimal point as the numerator, and simplify. For example, looking at the number 0.1234, the number 4 is in the fourth decimal place, which constitutes 10 4, or 10,000. This would make the fraction 1234 The first multiple they all share is 12, so this is the least common multiple. To complete an addition (or subtraction) problem, multiply the numerators and denominators of each fraction in the problem by whatever value will make the denominators 12, then add the numerators. EX:Unlike adding and subtracting integers such as 2 and 8, fractions require a common denominator to undergo these operations. One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved by the product of the denominators of each fraction. Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator. The numerators also need to be multiplied by the appropriate factors to preserve the value of the fraction as a whole. This is arguably the simplest way to ensure that the fractions have a common denominator. However, in most cases, the solutions to these equations will not appear in simplified form (the provided calculator computes the simplification automatically). Below is an example using this method. a as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.

The Section Width is the width of the tire measured from the middle of the side walls (above the bead, below the tread). Fraction subtraction is essentially the same as fraction addition. A common denominator is required for the operation to occur. Refer to the addition section as well as the equations below for clarification. a The above tire size conversion chart does not mean that these tires are universally interchangeable. They are to give you a point of reference when upgrading your older tires. Consult your motorcycle’s manual or manufacturer’s customer service

Long multiplication means you're doing multiplication by hand. The traditional method, or Standard Algorithm, involves multiplying numbers and lining up results according to place value. These are the steps to do long multiplication by hand: An alternative method for finding a common denominator is to determine the least common multiple (LCM) for the denominators, then add or subtract the numerators as one would an integer. Using the least common multiple can be more efficient and is more likely to result in a fraction in simplified form. In the example above, the denominators were 4, 6, and 2. The least common multiple is the first shared multiple of these three numbers. Multiples of 2: 2, 4, 6, 8 10, 12 The vast majority of tires manufactured and sold today come with metric sizing. The tire size we will use for our example is a 120/70ZR-17TL. It can also be written as 120/70Zx17TL or 120/70ZR17TL. Proper fraction button is used to change a number of the form of 9/5 to the form of 1 4/5. A proper fraction is a fraction where the numerator (top number) is less than the denominator (bottom number).

Use long addition to add your number columns from right to left, carrying as you normally do for long addition. Similarly, fractions with denominators that are powers of 10 (or can be converted to powers of 10) can be translated to decimal form using the same principles. Take the fraction 1 The section width and rim size are defined in the same manner as described for the Alpha and Metric size formats. The majority of modern motorcycles and dirt bikes do not use these tires. These were standard equipment on older machines. The Inch or Standard Inch Size Format does not include an aspect ratio. The aspect ratio on these tires is 100. Meaning the section width and section height are equal. What do these terms alphabetical, metric and std inch mean? They are explained in a section below. The sizes in the above chart do not go as large as modern sizes (180/55 or 240/40) because new bikes are not made to use the Inch Format.

When you've multiplied the ones digit by every digit in the top number, move to the tens digit in the bottom number. Also, inch size format tires are all bias type. They do not come in radial. The size will will use for this example is 4.60x17H 4PR. You may also see this written as 4.60H-17 4PR. 4.60 Long multiplication with decimals using the standard algorithm has a few simple additional rules to follow. The Aspect Ratio is the tire section height divided by the section width (not tread width), multiplied by 100. The section height is measured at the center of the tire crown. The tread width is usually greater than the section width. The section width is measured from the middle side walls (above the bead, below the tread). It is
