The legend lives on. The latest generation of the Marathon has a new tread pattern, new puncture protection, new sidewall and new compound. Its well-known qualities have also been improved - higher mileage and better puncture resistance. KevlarGuard: The Kevlar belt has been improved. Not only is the protective layer both stronger and safer, but we also succeeded in making the material considerably more flexible. The result: The level of protection is higher, while the rolling resistance is lower! This tire also has a SnakeSkin sidewall protection for more resitance against sidewall abrasion.
