What must you ensure is not visible in your tire tread or sidewall?

Rubber
Fabric
Paint
Any markings

The correct answer is: Fabric

The presence of fabric in the tire tread or sidewall indicates that the tire has worn down excessively, exposing the underlying layers beyond the rubber. This exposure not only compromises the tire's structural integrity, making it more susceptible to blowouts and other failures, but also significantly decreases safety while driving. A tire that shows fabric is unlikely to provide adequate traction, control, or handling performance. In contrast, rubber is the intended material for tire performance and helps maintain grip on the road. Paint is generally not an issue with tire functionality, as it does not interfere with the tire's performance. Markings, which usually include the tire brand, size, and specifications, are standard and necessary for identification and compliance purposes. Therefore, ensuring that fabric is not visible is crucial for maintaining the safety and effectiveness of the tire.
