Is it necessary to replace both motorcycle tires at the same time?

[SebastianFitz]

It is recommended to replace both motorcycle tires as a pair. Below are specific situations when motorcycle tires need replacement: Insufficient tread depth: Each motorcycle tire has "tread wear indicators" marked near the tread on both sides. The extension lines of these indicators meet in the groove at the center of the tread, where you will find a raised bump approximately 1.0 mm high. If, when viewed from the front (not the side), the tread height is nearly level with this bump, it indicates the wear is close to the limit of 0.8 mm, and a new tire should be replaced. Excessively worn tires with insufficient tread depth can affect water drainage and increase the risk of skidding. Prolonged use: Even if the tread wear indicators haven't been reached, tires that have been in use for three years often start to harden, lose elasticity, and develop fine cracks due to environmental factors like temperature changes and UV exposure. In such cases, sudden temperature fluctuations or overinflation can lead to blowouts while riding. Puncture by foreign objects: If a tire is damaged by nails or sharp objects during travel, the safest option is to replace it. Although patching is an alternative, there remains a high probability of air leakage or blowouts due to structural damage to the tire body.
