GH Howie that is BS!!! Harley will most likely cover the tire. I pushed my dealership to send tire to Harley when Val's first tire E3 radials had a weird wear pattern. Everyone at the dealship said the same thing to many miles. Guess what Harley covered 2 tires and the 3rd one a D407 looks is worse than the E3's. I sure it will be covered under warranty. The problem is no one ever reads the maunfactures waranty ploicy. They think it is based on mileage. It is not!:
"If, during the first fifty percent (50%) of tread wear, the tire becomes unserviceable for a condition covered by this warranty, it will be replaced with a comparable new Dunlop tire. You pay only for retailer services, such as mounting and balancing. If, after the first fifty percent (50%) of tread wear, the tire becomes unserviceable for a condition covered by this warranty, your Dunlop motorcycle tire retailer will replace it with a comparable new Dunlop tire at a cost calculated in the following manner:
After 50% wear:
Either your original buying price substantiated by invoice, or the retailer's current selling price, times (x)
Fifty percent (50%)
Plus (+) all applicable federal excise taxes, and local taxes and all charges for retailer services such as mounting and balancing
A CASH REFUND WILL NOT BE EXTENDED IN LIEU OF THE ABOVE.
GH tell your dealer to apply for warranty!
