I finally convinced the old man that he should ship his bike out to Utah so I could get it running and keep it running. He bought it new in 69, then it sat for most of my life until a few years ago when it was running great. Needs a little work now, mostly a little rust in the tank and some carb work. My question is the tires. The rear is original. Yes, as in 1969 rubber. He has the original front tire too, but that was replaced a few years back. I live 2 miles in on a 10% grade dirt road (2 miles 1,00 vertical feet). I'm looking to replace the tires with something more 50/50 dirt/pavement or maybe slightly more pavement orientated (70/30?), but want to keep with the appropriate look. Original tires are front 3.25" X 19" and rear 4.00" X 18" both Dunlop. I'm thinking about keeping with Dunlop and going with the K70s. I see lots of great looking tires in pics here, but it's hard to read what they are. Any advice or recommendations?
