What information is required to be molded on the sidewall of all passenger tires within the first six months of production?

The correct answer indicates that the sidewall of all passenger tires must include information regarding treadwear, traction, and temperature. This information is essential for consumers, as it provides critical insights into the tire's performance characteristics under various conditions.

Treadwear information gives an estimate of the tire's longevity and how well it will perform over time, which is vital for planning replacement intervals. Traction ratings inform the driver about the tire’s grip on wet surfaces, significantly affecting safety and performance. Temperature ratings indicate the tire's ability to dissipate heat, which is crucial for preventing blowouts or performance degradation during extended use.

Together, these ratings help consumers make informed choices based on their driving habits and conditions, enhancing overall road safety. Regulations dictate that manufacturers must include this information on the tire's sidewall to ensure that all tires meet certain safety and performance standards.
