This is achieved with the tread design, the stronger structure, and the tread's self-cleaning nature. The stabilized tread elements with the rigid center elements avoid tread damage, such as the tread's chipping, cracking, and tearing. The reinforced construction protects the casing from punctures, cuts, and impact damage. The tread's self-cleaning ability eliminates rocks stuck between the tread elements, effectively preventing stone retention from shortening the service life.
