I needed to replace my rear tire since it was worn so I decided to purchase a dual sport rear tire. The Shinko 244 Dual Sport Tire. Since I ride on a wide variety of surfaces I felt that knobbies were not best suited to my needs. I ordered the 2.75×19 inch tire. I estimate that it is about 3/4 of an inch taller overall than the stock tire. To date I have found that the grip on pavement, gravel fire roads and dirt is great.
