Need new front and rear tires. Mainly hardpack riding here in Virginia. however I also ride some MX and trails in Maryland, PA and NC. Considering the Pirell Scorpion Pro for the front and the MT-16 for the rear. Currently have Dunlop 739FAJ front and 120/90-19(stock is 110/90-19) D739 for the rear. Should I seriously consider the Pirelli or stick with the Dunlops? What is the handling differences between these two tires? Where do you guys get tires from? How does the Pirelli front tire special work?
