The Marathon Industries 30326 13 inch x 5.00-6 inch Turf Tread Lawn Mower Tire is made of solid rubber to make it impervious to flats. With trillions of air cells and reliable bounce, it performs like an inflated tire. This flat-free tire has a heavy-duty rim and a turf tread for a firm grip as it moves across the yard. With non-marking skin, it leaves behind no streaks on a garage or shed floor. It is also UV-resistant and resilient against cold and heat. The Marathon tire is compatible with a variety of riding lawn mower models and is commonly used as the front tire.
