The Duro DI2019 front and DI2020 rear tires are designed for sport and full sized ATV's that are primarily used on hard-packed terrain. The Scorcher tires are ideal for blacktop, cement, gravel roads or turf. They are easy on the turf and won't tear your grass up like knobby or aggressive tire tread patterns would. We've had very good luck with our Duro Scorcher tires and have had many satisfied customers that need performance on hard pack terrain.
