I am using the Dunlop American Elite Gen II. Front wheel is 2008+ Softail so it is the standard 130 x 16. The rear wheel is a 2009+ Road King rim laced to the original Dyna hub so it uses a 180 x 16.
My father is in Florida right now and had an old previous Shovelhead owner wondering how he got a Twin Cam into a 4 speed frame yesterday. He loves it when people get confused, He owns 4 Shovelheads so he knows the details needed. He claims to have machined a bolt-on Shovelhead rockerbox cover. He decided to make the 2nd one when he gets home.
Here are two of his Shovels. The one on the left is probably closing in on 150k miles. The 1983 on the right has 14k original miles.
Will probably post a few more pictures this week for your viewing pleasure.
