I am headed to Alaska this Summer and would like to put on some more dirt friendly tires on my KTM 950 Super Moto. The wide 17' rims are a problem and I am not interested in swapping them out. I don't need knobbies, just something a little better for gravel and an occasional good dirt road. Stock rear 180/55/17 Stock front 120/70/17. Any ideas? Thanks!!
