The aspect ratio refers to the height of the cross-section of the tire to its width. This is a two-digit number that is usually slashed after the width of the tire. For example, you can say that the size of the tire is P215/65, which means its width is 215 and has a 65 aspect ratio. The 65 means that the tires aspect ratio is 65% of the width
The higher that first number, the wider the tire. The 55 is the height of the tire expressed as a percentage of the width we just saw. The lower this number, the shorter and more aggressively the
Step 1: Put the Bike Upright. Set up your bike with a kickstand, or you can also lean it up on a wall. A firmly held bike is easier to measure. It will also avoid movements that may affect your measurement accuracy. Three ways you can measure your tire are: by using a ruler, calipers, or a retractable measuring tape.
55 refers to the profile of the tyre, or the distance between the wheel and the edge of the tyre, looking at it from the side. The number is the percentage of the width of the tyre. It is commonly known as the “aspect ratio”. So, the profile of our example tyre is 55% of 205mm, or 112.75mm. This number also increases in increments of 5.
Now, this information could read in a few different ways. For example, it could simply say 35x12.5 R17, or it may show as P265 75 R15. If it is the first listing, then here is the breakdown. That first number is your tire size at 35", and then the second number tells you the tire width at 12.5". That third reading is the tire type as radial and
The number 17 refers to the diameter (in inches) of the rim the tyre should be fitted to. The number 99 is the load rating index, which tells you the maximum weight one tyre can carry (in this case, 775kg). Other examples include 89 (580kg), 92 (630kg), 94 (670kg) and 95 (690kg). Legally you need to make sure the tyres you buy have at least the
To accurately evaluate and compare these measurements, a tire calculator can be highly beneficial. It allows you to examine various tire sizes and comprehend how these dimensions could alter your driving experience. For a straightforward and user-friendly tire calculator, you can visit this link: Tire Size Calculator. Utilizing this tool will
The number "205" is the tyre's width in millimetres.This number indicates the width of the tyre from one sidewall to another. The number "55" is the aspect ratio of the tyre. It represents the height of the sidewall as a percentage of the tyre's width. In this instance, the sidewall height is 55% of the tyre's width.
For example, a 29 x 2.25 mountain bike tire is about 29” in diameter and about 2.25” wide, while a 700c x 25 road tire is approximately 700mm in diameter and 25mm wide. This makes it pretty straightforward to fit a modern tire to a modern rim—a 700c tire will almost definitely fit a 700c road rim (we’ll explain that “c” later), and
This breaks down to: 25 = the overall height of the tire in inches at its proper operating air pressure. 10.00 = the width of the tire in inches when inflated to the proper operating air pressure. D = the tire's construction type. 12 = the wheel size. Truck or car tires likely wouldn’t fit on a UTV or ATV without serious modifications.
The three-digit number following the tire type code is the width of the tire measured in millimeters from sidewall to sidewall. The tire in the example has a width of 225mm. HOW TO READ THE SIDEWALL OF A TIRE You can convert the width measurement from millimeters to inches by dividing the width by 25.4. For example: 225mm / 25.4 = 8.86” TECH TIP
