Scuff tires in NASCAR are used tires that have been previously raced on and have some wear, but are not completely worn out. These tires provide a balance between grip and durability, as they offer more traction than brand new tires due to their slightly scuffed rubber surface. Teams may choose to use scuff tires during practice or qualifying sessions to save new tires for the race, as they can still perform well under specific conditions. The strategic use of scuff tires can help teams manage their tire inventory throughout the event.
