The process involves applying a substance to the tire tread and observing the wear pattern after a short drive. This visual inspection reveals how evenly the tire is contacting the road surface. For instance, a thick line remaining in the center indicates over-inflation, while wear on the edges suggests under-inflation. Uneven wear across the tire points to alignment issues.
This method offers a practical and cost-effective way to optimize tire pressure for specific vehicles and driving conditions. Proper inflation extends tire life, enhances fuel efficiency, and improves vehicle handling and safety. Historically, this technique has been employed by vehicle enthusiasts and professionals to fine-tune their setups beyond factory recommendations, ensuring optimal performance and longevity of the tire investment.
