What does 622 mean on bike tires?
The 28/32 refers to the tire size . I interpret it to mean you can use tires of 28mm to 32mm width. Most modern road bikes can fit 32 mm tires, and that is a very good thing. Even featherweight pro racers are on 30 mm tires—a little extra width makes sense for the rest of us. You still get the ‘connected-to-the-road’ feel that makes road bikes so much fun, without harshness, even on rough pavement.Most race bikes these days will come with either 25c or 28c, and these sizes are best for minimising rolling resistance. For endurance or sportive bikes, 28c or 32c tyres are most often used, allowing for greater comfort over long distances. Wider tyres are able to deal with rougher roads easier.
What size tire is a 622 rim?
Tires with diameters 622 mm and 635 mm are both classified as 28 inch. Oddly enough, tires with an inner diameter of 630 mm are classified as 27 inch. These classifications originate from the time of tire brakes. In those days, the exact outer diameter of the tire was defined by the brake. ISO 622 mm) Here we have two more common wheel sizes that are in fact, exactly the same! The standard modern road bike wheel has an ISO diameter of 622 mm and is referred to as 700c (makes sense, right?The “700” is stating the diameter of the bicycle tire and “c” is the width size of the tire. However it’s not 700 millimeters it’s 633 millimeters.
What is the 3 tire rule?
The Tire 3% Rule Explained The Tire 3% Rule states that your tire’s measured width should not exceed more than 3% of your rim’s internal width. It’s designed to prevent a tire from “bulging” wider than the rim, which increases the risk of: Poor sidewall support. Reduced cornering stability. The 3% rule states that when replacing tires, the new tire’s diameter should not differ from the original by more than 3%. This guideline helps maintain proper vehicle performance, safety system functionality, and speedometer accuracy.The 3% tire rule is a guideline for upsizing tires. It recommends keeping the new tire’s diameter within 3% of the original to avoid affecting performance and safety.
What is the 105% rule on tires?
The 105% rule says that the external rim width of your wheel should be at least 105% of your tire’s actual measured width. This ratio allows the airflow to remain attached as it moves from the tire onto the rim, reducing drag and making your bike more aerodynamic. It has often been said that to have good cycling wheel performance, there is a rule that the external rim width of a wheel should be at least 105% of the width of the tyre, or that there is a simple relationship/formula that will predict the aerodynamic performance of a wheel based on rim width vs tyre width.
What is the 3% rule for tires?
As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of the tires originally on your vehicle. If they’re too large, they could scrape on the inside of the fender every time you make a turn. As a general rule, you want replacement tires that are within 3 percent of the diameter (height) measurement of the tires originally on your vehicle.
