Product Information

The size in inches with two numbers, for example 28″× 1¾″, where the first number indicates the outside diameter of an inflated tyre in nominal inches and the second number indicates the height from the bead to the top as well as the width.

It is common to designate metric fine threads with the capital M plus an indication to their nominal outer diameter and their pitch: For a near approximation of wheel circumference, you can find tire size written/molded into the side of your tires. Find that tire size in the chart below and enter the corresponding value in meters. The paper formats that are available within the ANSI are comparable to those on offer in the ISO standard in that dividing a sheet in half will generate two sheets in the next size. For the most accurate data from a speed sensor like the Wahoo RPM Speed or Blue SC, measure and input your wheel circumference in the Wahoo Fitness App. An accurate speed sensor can also improve the speed/ distance data accuracy of GPS Bike Computers like the ELEMNT, ELEMNT ROAM, and ELEMNT BOLT, especially in tree cover or near buildings. All tyres are marked with a pressure. Sometimes this is an absolute maximum that nobody should need to exceed, or sometimes only a recommended maximum that may be exceeded by heavier riders (such as tandemists).To perform arithmetic operations on scientific notations, use our scientific notation calculator. Scientific notation to standard form: BSPP (G) - British Standard Pipe Parallel and BSPT (R/Rp) – British Standard Tapered Pipe for pipes and tapered threads - G/R/Rp. Bicycle tires come in a variety of sizes, mostly depending on the type of the bike and the terrain you're riding. So when shopping for new tires, you'll need to know exactly which will fit your rims. Inch based identifications indicate the width in a decimal (26 × 1.75) or as a fraction (26 × 1 3⁄4), and although these size identifications can be mathematically equal, they also can refer to different size tires, which are not interchangeable. ( 28 × 1 1⁄2 is not the same size as 28 × 1.50)

While a range of paper size standards is in use at present, two systems are particularly common: The North American system and the international system, which is also referred to as ISO 216. When scientific notation is applied, a large number is transformed into a corresponding decimal number that is between 1 and 10, multiplied by 10 raised to a given positive power, and small numbers are transformed into a corresponding decimal number between 1 and 10, multiplied by 10 raised to a given negative power. While traditional sizing systems are based on the outside diameter of an inflated tire (measured in inches or millimeters), the ISO standard notation uses the diameter of the wheel bead seat in millimeters preceded by the inflated tire width in millimeters. The size in mm according to the European ETRTO standard, for example 47—622, where the first number indicates the width of the inflated tyre and the second the inside diameter in mm. If the rim is not marked with its bead diameter you can read this from the tyre – it’s the one dimension they have in common.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.

Tyres suitable for use with dedicated tubeless rims, or with a conversion system which employs tape to seal the rim bed, are marked using a sidewall decal such as tubeless-compatible, tubeless-ready, tubeless-easy or similar. They have a special stretch-resistant folding bead made, usually, of carbon fibre. How do you know what size tyres will fit your bike? It should be easy: buy exactly the same model of tyre as those already on the bike. Of course, this isn’t much help if identical tyres aren’t readily available, if you fancy something different or if you’re looking for replacements in unusual and hard-to-find sizes. To write scientific notation in other forms, you can use the calculator above. But let’s also see the manual process. Scientific notation to decimals: The size in inches with three numbers, such as 28″× 1?″× 1?″. In this case the second number is the height and the third number is the width.Even worse, the same or very similar markings can sometimes be found on completely different sizes of tyre: 26×1½ and 26x1.5. It might be supposed that these two tyres are both notionally 26" diameter and one and a half inches in width, but 26×1½ is a whole inch bigger than 26×1.5. Used on mountain bikes, these tires also go by the names: 27.5+, 650+, 6Fattie, or even just "Plus tires". ISO / ETRTO (mm) In engineering, fractions are widely used to describe the size of components such as pipes and bolts. The most common fractional and decimal equivalents are listed below. 64 th One way to define it, popular in times past, was to measure the tyre’s outside diameter and its maximum width when inflated, but this can be misleading. For example, some tyres marked 28" are actually much less than 27 inches in diameter, while 26×1.5 and 26×1½ are two completely different sizes. Requirements for thread form, dimensions, tolerances and designation for fastening pipe threads, thread sizes.

Two tyres with the same ISO markings are completely interchangeable, even if one seems to be metric and the other is also marked in inches. For example, 650B and 26×1½ are both 38-584 and should be marked accordingly. Look for the ISO numbers and you always know exactly where you are. That’s how the diameter and circumference (circ – equals distance rolled in one turn of the wheel) are calculated in the Tyre size table. These figures are useful for setting your cycle-computer and precisely calculating gears.

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
