I posted same question under Dyna forum oooppps. anyway, anyone know the stock tire on a 2008 super glide? Run of the mill Dunlop or did they have HD on the sidewall?

 

My 2007 FXD Super Glide did have the Dunlops with the Harley-Davidson logo on the tires. Replaced the K591 on the rear at about 12k miles. Front D401 is about to be replaced at 20K miles. I would think the 2008 wouldn't be much different. Somewhere along the way many of the Dynas moved to Michelin's as the stock tires.

 

Your original tyres will have had HD branding, however all the premium tyre brands make direct replacements, so there are plenty of options.
