If the bike is upright, you can measure the bike wheel except the bike tipping onto you. Here are some easy steps on how to measure bike tire size.
First of all, you have to measure the diameter of the tire. Here’s our guide to road bike tyre pressure. Ensure the bike is propped up against the wall or on its kickstand.
It gives the width of the tyre against its height as a percentage. Place the end of a tape measure at the exact center point of the gear crank (the metal post that runs through the center of the bike’s chain sprocket). Enter bicycle shop we have a large selection of cruiser bicycles for sale.
Put the bike upright against a wall, or you can use the kick stand. To measure your bike’s frame size, take a measuring tape and place the tape in the center bolt of your bike’s cranks. The iso size comprises two numbers separated by a dash.
Simply put, as the rim’s internal width gets bigger, the tire will measure wider. See load index table for car tyre load index ratings. However, these tyres can cost more and be noisier.
When it comes down to measure the bike tire size, you need to follow some steps. People still fit them and get on just fine, but it’s not always. The tyre width is 28mm.
See speed symbol table for car tyre speed symbol ratings. Now run the measuring tape up your seat tube. Our tyre size guide will clear up any confusion you have when selecting the right replacement tyre for your bike.
With riders electing to use various widths of tyre, there’s no longer a ‘one size fits all’ tyre pressure. Once again, double the figure to determine the diameter. The tyre height is 1 5/8 inches.
Then run the tape measure up to the top of the tube. If you are unable to match the markings with a swytch wheel size, you can measure the wheel size yourself: Once the bike is upright, it will be easier to measure the wheels without shaking or tripping over.
Take down this measurement in mm. Measure in millimeters from the center of the wheel to only the inner edge of the tire. Depending on the kind of bike you ride or want to ride, will determine your size along with your riding style.
If it is just the frame, this will be the center point in the bottom bracket shell. Load index 91 is a code which indicates the maximum load capacity of the tyre. The distance from one end to the marked point is the circumference of your bike tire.
After all, the tire doesn’t have to go “full circle”, the center section is taken care of by the rim. Step 1 lean the bike on the wall on an upright position. Mark or cut the string on the spot where the string reaches the straight point.
So that’s quite easy to measure, although be careful to keep your bike straight upright for an accurate reading. Measure your bicycle wheel and tire size with table. Measure spot from the first spot to the next spot to determine the tires circumstance.
When you reach the end of the seat tube, you have your frame size. Measure to the point where the tube ends. There are essentially five parts to a clincher tyre (standard tyres that use inner tubes, held in place by a bead that hooks to the wheel rim, as opposed to tubulars that are bonded to the wheel):
This is the most common type, where the tyre hooks to either side of the rim using a bead. To measure the circumference, evenly wrap a string around the outside edges of the tire. Check the bead diameter of the tyres on your bike.
Stand the bike up using a kickstand, or just lean it against a wall. Then it’s time to measure the width of the tire. Most lists the tire size both english, french and german targets and rim circumference in millimeters.
If you are unsure of your bicycle tire size, you can look into a bicycle tire table where you can easily and simply find just the tires that fit your bike.

If you are looking for information about tyre choice for different disciplines, surfaces and performance goals, look at our road bike tyre guide or mountain bike tyre guide best tyre for your bike, including rubber compound, tread.

This is the inner radius of the tyre (r). This is the bead diameter at which the tyre fits onto the rim. In general, a tyre that has a low profile, or short sidewalls to their width, will give a firm ride and good handling;
Most adult bicycle tires measured with the iso system range from 650 to 700 millimeters in diameter. Many times people misunderstand what is meant by wheel size. The wider the rim, the bigger this center section and the more tire is available for create a bigger “circle”.
But, at least you need to know all of the basics to do it. The outside diameter is used to measure the aspect height or tyre profile, which is dictated by the sidewall. Assuming of course the bigger tyre fits your smaller capacity bike.
Measuring the bike tire is not rocket science at all. Outside of road, mountain bike and hybrid, there are three overarching types of bike tyre: If you’re ever thinking of going up to a 190 on a smaller bike such as a 600 or 750, please know that many 190+ width tyres are designed for 6 inch wide rims, where as many smaller bikes have 5.5 inch rims.
