The C628 tread features a knobby tread that provides great traction on a variety of surfaces PLUS the foam fill gives you the peace of mind that you will never get a flat tire!You should be sure to measure your bead width before ordering to ensure that the tire will mount to your rim properly. To measure your existing tire you should measure from the outside edge to outside edge of the tire (as pictured).If you don't have the tire and need to measure your rim/wheel you should measure from the inside edge to inside edge. Once you note this measurement you should add approximately 1/4 inch to this as the tires are sold by their outside measurement.
