Bicycle tires have two components. The longer number of the tire is in diameter about an inch, and the smaller number is the tire width in an inch.
The range of tire diameter is 12 to 26 inch, and the width diameter is from 1.75 to 2.215 inch.
The International Organization for Standardization measures tires diameter by millimeters along with inner diameters.
This is known as bead seat diameter. If you know only one size, it is difficult to replace the tires.
Most of the tires have imprinted measurement on the tire, and over time it becomes worn and impossible to read out.
What type of bike wheel good for me?
Wheels will be the primary port of call if you’re looking to improve your bike to make it lighter or to manage better to get a much better biking experience. A brand new pair of bike wheels may alter the ride texture of your bicycle. Wheels are manufactured from three primary part parts; the rim, spokes, and pulse. Our guide will guide you through a variety of wheel kinds and which wheel is ideal for your bicycle.
Mountain Bike Wheels
Deciding the proper mountain bike brakes can be complicated but do not let this put you off since the ideal set of wheels may produce a bicycle feel entirely different! The best MTB wheels vary from lightweight (1300g) race versions to super powerful downhill options, prepared to take a beating. Broadly, mountain bicycle wheels for all-around use ought to weigh in the area of 1700-2000g for your set.
Together with most riders today using disk brakes, rims often do not have machined braking earth surfaces, and the connecting hubs have between 2 disc-mounting systems. Six-bolt has become the most common standard, although some Shimano hubs utilize their Centre Lock system. Assess that’s on your bicycle already if you are updating, but it is simple to swap rotors about if your heart is set on a specific mountain bike wheelset.
Most hubs utilize cartridge bearings, and after you’ve found the posture number, they are easy to change when they wear out. Shimano hubs use a cone and cup system using loose bearings – that they could endure for ages but require a little more TLC.
Before taking the plunge and spending a pair of wheels, ensure the axles will fit your fork and frame. Some downhill frames might have 150mm rear spacing. Luckily most brakes can put up a selection of axle criteria.
Road Bike Wheels
Road bicycle wheels are readily available for total budget. When deciding on a new pair of wheels, you first must check at disk or non-disc, based upon your bicycle, but layouts are like the two, and there are 3 main choices: standard metal road wheels, light brakes (made for scaling) and heftier aero-profiled wheels (made for velocity).
Lightweight road bicycle wheels will make scaling mountains simpler, and also the very best street wheels needn’t cost the earth. Wheels such as Fulcrum’s Racing 3 weighs only over 1500g a couple and have smooth ceramic bearings in the hubs and a mild metal rim and aero-bladed spokes.
If you’re trying to find the very best street bicycle wheels, then you need to remember that using a mild rim means less rotating weight (much more noticeable than weight anywhere else on the wheel), that will have a positive impact once the road begins to steepen. This is only one of the benefits of disk brakes since they don’t require aluminum steering that there is less weight round the rim.
Imperial, Metric & American
Sometimes you will get ISO size tire, the old type of helmet, though they are very confusing.
Tires looking same have various sizes in the market, e.g., e.g. 28×1¼×15/8, or 28×1¾×1¼ or 700×32C are all 32–622.
Similar, worse and same marketing be found in various sizes of tire: 26×1½ is a whole inch bigger than 26×1.5. Use this section to convert ISO and have nothing to do with markings.
Indicates to the column headed Imperial, American or Metric to work out the size you like to get.
For first two headings, there is no explanation. The American column is to originate the tire size in USA and US marketing may be confusing.
The Japanese and the American branded road tires is similar than described one and has lack of ISO marketing
Two tires having same ISO marketing are well interchangeable though seems to be metric, though other is marked as inches specially 650B 26×1½ are both 38-584 needs to mark well.
See the ISO number and be sure about the size. Some rims are made with the same bead diameter of ISO brand and internal section.
Normally 622-17 is great for touring and for hybrid bikes. But manufacturer offers the overall width.
Subtract six mm to consider the rim section, normally measure the flanges. If there is no indication of bead diameter over the ring, you may read it from the tire. One dimension, they have common.
The real relationship of the rim and tire is about 1.8 to 1 but tires from 1.4 to 22. times must fit, give bead diameters correspond.
At present all rims hold hooked flanges which are changed three times width. It may create confusion.
If the tire is fit for the narrow rims, you will feel more comfortable. It also rolls easily. It also increases the stress of sidewall of the tire.
Road tires have no stress, but Mountain bike tires have extra stress. Another thing it may not exceed 2.2 limits over the road which bulbous tire may deflect sideway having the visible effect of maintaining road holding.
The fitness of tire having 1.4 times less than rim section may result in a harsh ride and rolling drag instead of big tires with similar pressure.
Calculating the Circumference of a Bicycle Wheel
Measure the distance or circumstance around the outer part of the bicycle wheel to calibrate odometer or speedometer of a bicycle, GPS, and computer.
If the sizes of wheels are changed the odometer or speedometer will give a wrong reading.
The reason is that you have switched the tires with variously sized treads; simply you can measure the wheel’s circumstance.
Measure the size of the tires by using pin 4. If you are aware of the diameter of the tire, you may quickly determine the circumstance.
Pi is same as 3.14. The area of a twenty-six-inch tire may be reached by multiplying 26 X 3.14 same circumstance of 81.64 inches.
If you have knowledge of tire’s width and diameter, you may look at the situation on various online charts.
Measure the atmosphere or circumstance with the string. If you do not know the accurate measurement, you can wrap a string around the edge of the wheel to get the accurate size.
Cut or mark the string to the spot where it goes back to the starting points and then measures it to detect the circumstance.
Use more wet paint on the spot of bicycle tire’s tread. Push bicycle in the line for at least two rotation confirm paint marks in the ground twice.
Measure spot from the first spot to the next spot to determine the tires circumstance.
How to measure bike wheels in inches
- Put the bike upright against a wall, or you can use the kick stand. If the bike is upright, you can measure the bike wheel except the bike tipping onto you. Since you are thinking only the bike alone, a retractable metal tape will be a better option than the plastic tape as it leaves a free hand to you.
- Take a measurement tape and measure the distance from tire to the middle of the wheel in inches. The measurement is half of its diameter or the wheel’s radius. Multiply the length by 2 to compute the tire’s diameter. Only the exceptional is BMX models, most of the adult wheels are between 26 to 29 inches in diameter.
- Measure the flat part of the tire along the thread from one side to another. The tire’s width is the distance. It can vary as it depends on the tire’s desired use. If the threads are wider, the terrains will be rougher though narrower treads ensure faster and smoother ride.
- At the time of buying a new tire, keep the diameter first, instructed by the width. Suppose, a tire sized 26 x 1.75 will have a 26-inch diameter and 1.75-inch width across the tread.

Sizing Kids’ Bikes – Tips for Parents
Some quick tips for sizing
Do not think your kiddo’s tallness- development spurts mean you must take an instant measurement.
At first, measure the height of your child. Then see the size guide to get the exact size bike for the height of your child. There remains some overlap, therefore, ensures them the super range to grow. Most of the kids’ bikes are measured according to the wheel size.
You can be tempted to strike them up a size to grow into- so it is better to give them comfortable and safe than getting other months of growing time on a bike.
Be confirm you child has same as the motor aptitude to operate a bike. Some bikes come with one hand brake and shifters that demand more skill to operate. Stick along with coaster brakes as you child is more experienced and older.
Follow the instruction of setting up, give every bolt a double check before you child take it outside to ride on.
Put the seat to the adjusted height so that you kids can place the ball both the feet on the earth. For the new riders, you may move as low as feet flat on the earth.
Be sure the helmets are super tight and worn above the eyebrows. Adjust the jaw strap round the ears, tight more to enter a couple of fingers under the strap.
