I just got new set don't have a depth gauge but I would say 5mm by looking at them. The tires have wear bars or indicators and the legal limit is .8mm
or 1/32 of an inch well a few states its 2/32. Sounds like they want your money the Harley shop wanted to charge me $400 for tires and about another $200 to put them on ordered them from revzilla for $260 and bought $200 worth of tools and a lift and did it myself h a friend was some work but saved some money and learned something! I found it the deepest part of the tread on new tires the rear scorcher 11 is 4.73mm or 6/32 inch.
