I need to replace the tires on my 2011 Fatboy. The original tires are the Dunlop 408F 140/75R17 on the front and the Dunlop 200/55R17 on back. I see these tires are available only from the dealer and they are pricey. Any other Dunlop designations for the same tires? If changing brands, are there any recommendations? I'd like a little more traction even those these tires weren't bad and I'd like at least as much wear, better would be good. Rear was replaced once due to a bad flat, the front is about done at 6200 miles, the rear is also not too good with about 4200 on it. Thanks!
