Prevent Tearing. New full pull tab design for easy removal. Made of 1000 denier Cordura nylon material. Developed by Dupont, this is the same material used in United States military gear. Don't be mislead by others claiming denier of a lesser count or some who bill out Condura instead of Cordura. These covers are simply one of the best covers you can put on your car. These Jr dragster tire covers are extra wide and are USA designed and developed for maximum protection and life.
