Facts & Figures
Improved tyre mileage is a compelling benefit: This graph shows the relative difference in tyre life at various bearing adjustments for trailer or drive axles. Commonly used loose settings of 0.002 to 0.005 endplay typically lose half to three quarters of potential tyre life, largely because loose wheels initiate and accelerate edge wear.
