Hi Everyone, I'm building a dual-sport Ducati Monster 750 and need to convert from road to dual sport (50/50ish) tires. My question is about rear tire sizing: It currently has a 160, but I don't see a 160 size in the rear tires that I'm considering: Conti TKC80, Heidenau K60 Scout, Shinko 705 or 804, Metzler Karoo, etc. I see a 150 or a 170 rear, so my question is: Which is a appropriate size? The rim size is 4.5"x17". The spacing of the swingarm can accommodate a 170 and it will fit the 4.5" rim, but I'm curious to understand if narrower or fatter would better. The 170 would give me a little more height as well, since I'm working to increase the ground clearance a bit, including building up the stock seat's front bucket to get me higher on the bike. Type of roads: Northeast US country dirt/mud, loose gravel, fire roads, etc. The dirt when muddy can get a little deep, but probably not more than 2-3", though it's slippery...almost red-clay-ish. Thanks for any insights.
