OEM 407 & 408’s for my 2009 CVO springer wore out by 5,000 miles with no hard ridin’, luckily front cupped & covered by known field bulletin & warranty but neither Dunlop or HD cared about the 240 wide rear tire.
I went with Avon Cobra’s for 10,000+ miles & better tracking on the road.
Thinking about the Dunlop American Elite next time, the 240 rear has deeper thread & hear better mileage from other owners with more of the narrower tires, but I did not appreciate Dunlop or HD customer service when I complained of their advertised “high mileage” & “two-compound multi-tread” tire not living up to their name.
I would go by the experience from owners of the same model & year you have, my CVO springer is a little different than most of the other CVO’s...
