The Chieftain has blackwall tires instead of the wide whitewalls that come with the Vintage and Classic. I like the old-school look of the whitewall tires and was wondering which tires I can get to achieve that look without compromising safety when it comes time to change them. The bike comes with Dunlop Elite 3 130/90B16 73H in front and 180/60R16 80H in the rear. The spec sheet shows the Chieftain only 18 lbs heavier than the Vintage with a full tank. Any tire guys out there who can shed light on this?
