Dunlops for me. I just replaced both last September. It seems most folks get the best mileage with Dunlop. And I can get them mail order for a great price. I figure if they're good enough for Harley, they're good enough for me.
Dunlop Elite III front and rear. Handle far better than the OE Dunlops and last longer than the Metzler ME 880. 2007 FLHTCU with 86,000+ miles on the clock. Usually get 10-12k out of a rear tire and change the front with every other rear.
