Understanding tire peak friction is critical for accurately assessing vehicle stopping distances. While skid trailers have traditionally been used for this purpose, their results often lack repeatability due to track and weather variability. Indoor testing offers a more controlled environment, though it still depends on methodology and system setup. This presentation will explore slip control techniques that enhance repeatability in indoor tire friction testing, enabling more reliable comparisons across tire specifications.

• Demonstration of slip control techniques to improve consistency
• Role of methodology and system setup in test repeatability
• Advantages and challenges of indoor tire friction testing
• Importance of peak friction in vehicle stopping distance analysis
