A tire that is too low on air can develop bulging or flat areas, which is a clear indicator of under-inflation. When a tire is properly inflated, it maintains its shape and firmness, providing a stable contact patch with the road. However, when the air pressure is insufficient, the tire can deform, leading to visible bulges or flat spots. This deformation can cause poor handling and increase the risk of a blowout, making it crucial for motorcycle riders to regularly check tire pressure and inspect their tires for any signs of irregularity.

Other signs, such as high-pitched noises, excessive tread wear on one side, or vibrations in the handlebars, might also indicate issues with the motorcycle, but they are not specifically linked to low tire pressure. For instance, high-pitched noises might be more related to the bike’s mechanical components, while excessive tread wear could indicate misalignment or improper riding habits. Vibration in the handlebars can be associated with a number of issues, including wheel balance or tire damage. Therefore, recognizing bulging or flat areas is the most direct and immediate sign of an under-inflated tire.
