Note that the inch-based designations sometimes express the width in a decimal (26 x 1.75) and sometimes as a common fraction (26 x 1 3/4). This is the most common cause of mismatches. Although these size designations are mathematically equal, they refer to different size tires, which are NOT interchangeable.
Stomach bloating may at times occur immediately after a meal, within minutes or in rare cases while eating. The most common cause for this is due to air swallowing (aerophagia) or consuming carbonated drinks. In both these cases, it can be avoided to a large extent.
Gas is the most common cause of bloating, especially after eating. Gas builds up in the digestive tract when undigested food gets broken down and when you swallow air. Everyone swallows air when they eat or drink, but some people can swallow more than others, especially if they are: eating or drinking too fast.
