I bought my 250ex new about two years ago. I noticed I needed new tires and I wanted Razrs. My stock tire size is 22x10-9. They do not make a Razr that size so I bought a tire/wheel package with Douglas .160 wheels so that the wheel could accomodate the tire which is 22x11-9. Did I need to buy new wheels to fit the Razrs? Would the Razrs fit on my stock wheels?
