Thank you for your feedback. We're sorry to hear about your experience with the All-Terrain T/A KO3 tires. For concerns involving vibration, uniformity, balancing difficulties, high road force, or slow air loss, we recommend working with your dealer to confirm that the proper lubricant was applied to both the rim flange and tire bead during installation.
