The overall circumference of the tire will increase by increasing any of the tire's specifications. For example, increasing the width of the tire will also increase its circumference, because the sidewall height is a proportional dimension. Increasing the aspect ratio will increase the height of the tire and hence the circumference.
The inner width of the rim on which the tire is mounted should be about 65% of the tire's nominal section width for tires smaller than 30 mm and 55% for those larger. The section height of a tire is usually identical to its section width (for tires less than 28 mm, 2.5 mm have to be added to the width to get the height).
ETRTO sizes apply to rims and tyres for vehicles of all types, including bicycles. The great advantage of ETRTO sizing is that it is unambiguous; previously, nominal dimensions were used which were interpreted in different ways by different countries and manufacturers - a problem for the end user.
For bicycles with 700c wheels, some cyclists quote gear inches based on a nominal wheel diameter of 27 inches, corresponding to the old British tire size of 27 x 1 + 1 ⁄ 4" (ETRTO 630). Strictly speaking, the rolling diameter of a 700c wheel may be significantly higher or lower than 27", depending on the tire size, e.g. nearly 27.5" for a ...
In many countries, the law requires that tires must be specified, and fitted, to exceed the maximum speed of the vehicle they are mounted on, with regards to their speed rating code (except for "temporary-use" spare tires). In some parts of the European Union, tires that are not fit for a car's or motorcycle's particular maximum speed are ...
This is a list of auto parts, which are manufactured components of automobiles. This list reflects both fossil-fueled cars (using internal combustion engines) and electric vehicles; the list is not exhaustive. Many of these parts are also used on other motor vehicles such as trucks and buses.
The following outline is provided as an overview of and topical guide to tires: Tire (North American) or tyre (British) – ring-shaped covering that fits around a wheel rim to protect it and enable better vehicle performance by providing a flexible cushion that absorbs shock while keeping the wheel in close contact with the ground.
29er rims have an interior diameter of 622 millimetres (24.5 in) [1] and the average 29″ mountain bike tire is (in ISO notation) 59-622 – corresponding to an outside diameter of about 29.15 inches (740 mm). The typical 26″ MTB tire has a rim diameter of 559 millimetres (22.0 in) and an outside tire diameter of about 26 inches (660 mm). [2]
